Action taken (what you did)\n2. Expected result (what you hoped would happen)\n3. Actual result (unexpected outcome)\n4. Your setup (any and all relevant technical facts, error messages, logs, etc)\n\n### Feature requests\n\n* First consider if **you** yourself might be able to work on the feature? If so, check out info on contributing code below.\n* If you do not have the skills, then please take the time to clearly think through the request. Is is appropriate for all users of Gekko? If so, create a new issue containing the following:\n\n1. Write `[request]` as the first item in the title, followed by a short, concise description, eg: `[request] Export data to CSV`.\n2. Fill in details explaining your request. Be as clear and concise as possible and only 1 request at a time.\n3. Add mock-ups, etc as needed to clearly demonstrate the idea.\n\n## New Feature and code contributions\n\n- If you want to add an exchange to Gekko, see [this doc](https://gekko.wizb.it/docs/extending/add_an_exchange.html) for all the information you need.\n- If you want to Gekko react to anything from the market, you can most likely put this functionality into a plugin. See [this document](https://gekko.wizb.it/docs/internals/plugins.html) for details.\n- If you want to create a strategy, please see [this page](https://gekko.wizb.it/docs/strategies/creating_a_strategy.html).\n- If you just want to work on Gekko, you can use the open issues with the tag `open-for-pulls` for inspiration.\n- If you want to work on the web interface (Gekko UI), please see [this frontend doc](https://gekko.wizb.it/docs/internals/gekko_ui.html) on the Vue.js frontend.\n\nThings to take into consideration when submitting a pull request:\n\n - Please submit all pull requests (except for hotfixes) to the [develop branch](https://github.com/askmike/gekko/tree/develop).\n - Please keep current code styling in mind.\n" }, { "path": "Dockerfile", "content": "FROM node:8\n\nENV HOST localhost\nENV PORT 3000\n\n# Create app directory\nRUN mkdir -p /usr/src/app\nWORKDIR /usr/src/app\n\n# Install GYP dependencies globally, will be used to code build other dependencies\nRUN npm install -g --production node-gyp && \\\n npm cache clean --force\n\n# Install Gekko dependencies\nCOPY package.json .\nRUN npm install --production && \\\n npm install --production redis@0.10.0 talib@1.0.2 tulind@0.8.7 pg && \\\n npm cache clean --force\n\n# Install Gekko Broker dependencies\nWORKDIR exchange\nCOPY exchange/package.json .\nRUN npm install --production && \\\n npm cache clean --force\nWORKDIR ../\n\n# Bundle app source\nCOPY . /usr/src/app\n\nEXPOSE 3000\nRUN chmod +x /usr/src/app/docker-entrypoint.sh\nENTRYPOINT [\"/usr/src/app/docker-entrypoint.sh\"]\n\nCMD [\"--config\", \"config.js\", \"--ui\"]\n" }, { "path": "LICENSE", "content": "The MIT License (MIT)\n\nCopyright (c) 2014-2017 Mike van Rossum mike@mvr.me\n\nPermission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the \"Software\"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions:\n\nThe above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.\n\nTHE SOFTWARE IS PROVIDED \"AS IS\", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

This is only recommended for advanced users who feel comfortable editing config files and running shell commands.\n\nUsing the commandline you run one Gekko instance per command, eg. if you want to import 3 markets you need to run Gekko 3 times.\n\n## Configuring Gekko\n\nIf you decide you want to run gekko over the commandline you need to decide two things:\n\n1. What market / settings are you interested in?\n2. What should Gekko do? This is either backtest, import or run live.\n\nFor the first one you configure a config file: copy `gekko/sample-config.js` to something else (for example `gekko/config.js`). Configure the plugins to your liking. What plugins you need to enable does depend on the answer of question 2. Check the documentation under commandline for that feature.\n\n## Running Gekko\n\nFor live mode run:\n\n node gekko --config config.js\n\nTo backtesting run:\n\n node gekko --config config.js --backtest\n\nTo import run:\n\n node gekko --config config.js --import" }, { "path": "docs/commandline/backtesting.md", "content": "# Backtesting with Gekko\n\n*Note: this documentation was written for running Gekko via the command line.

The easiest way to get this is to let Gekko import historical data, however this is not supported by a lot of exchanges (see [here](https://github.com/askmike/gekko#supported-exchanges)). The second easiest and most universal way is to run Gekko on real markets using the UI (or alternatively via the commandline with the plugin sqliteWriter enabled). Though this takes a while, as you need to run Gekko for a week to have a week of data.\n\n## Configure\n\nIn your config set the `backtest.daterange` to `scan`. This will force Gekko to scan the local database to figure out what dataranges are available. If you already know exactly what daterange you would like to backtest against, you can set the `backtest.daterange` directly (set `backtest.daterange` as an object with the keys `from` and `to` and the values as a data parsable by [moment](http://momentjs.com/docs/#/parsing/)).\n\n## Run\n\n node gekko --config config.js --backtest\n\nThe result will be something like this:\n\n 2016-06-11 08:53:20 (INFO): Gekko v0.2.1 started\n 2016-06-11 08:53:20 (INFO): I'm gonna make you rich, Bud Fox.\n\n 2016-06-11 08:53:20 (INFO): Setting up Gekko in backtest mode\n 2016-06-11 08:53:20 (INFO):\n 2016-06-11 08:53:20 (WARN): The plugin SQLite Datastore does not support the mode backtest.

Note that this is a different plugin than the \"trader\" which is a responsible for actually creating orders based on this advice. (So if you want automated trading you need both this advice as well as the auto trader).\n\nDocumentation about strategies in Gekko can be found [here](../strategies/introduction.md).\n\n### Trader\n\nThis plugin automatically creates orders based on the advice from the \"Trading Advisor\" from the market Gekko is watching. This turns Gekko into an automated trading bot.\n\nBefore Gekko can automatically trade you need to create API keys so that Gekko has the rights to create orders on your behalf, the rights Gekko needs are (naming differs per exchange): get info, get balance/portfolio, get open orders, get fee, buy, sell and cancel order. For all exchanges you need the API key and the API secret, for both Bitstamp and CEX.io you also need your username (which is a number at Bitstamp).\n\nConfigure it like this:\n\n config.trader = {\n enabled: true,\n key: 'your-api-key',\n secret: 'your-api-secret',\n username: 'your-username' // your username, only fill in when using bitstamp or cexio\n }\n\n- enabled indicates whether this is on or off.\n- key is your API key.\n- secret is your API secret.\n- username is the username (only required for CEX.io and Bitstamp).\n\n### Advice logger\n\nThe advice logger is a small plugin that logs new advice calculated by Gekko as soon as there is any. Go to the config and configure it like this:\n\n config.adviceLogger = {\n enabled: true\n }\n\n- enabled indicates whether this is on or off.\n\nThe advice logged advice will look something like this in the terminal:\n\n 2014-01-15 14:31:44 (INFO): We have new trading advice!\n 2014-01-15 14:31:44 (INFO): Position to take: long\n 2014-01-15 14:31:44 (INFO): Market price: 5.96\n 2014-01-15 14:31:44 (INFO): Based on market time: 2014-01-15 14:31:01\n\n### Paper trader\n\nThe paper trader listens to Gekko's advice and on a sell it will swap all (simulated) currency into (simulated) assets at the current price. On a buy it will be the other way around.\n\nGo to the config and configure it like this:\n\n // do you want Gekko to calculate the profit of its own advice?\n config.paperTrader = {\n enabled: true,\n // report the profit in the currency or the asset?\n reportInCurrency: true,\n // start balance, on what the current balance is compared with\n simulationBalance: {\n // these are in the unit types configured in the watcher.\n asset: 1,\n currency: 100\n },\n // only want report after a sell? set to `false`.\n verbose: false,\n // how much fee in % does each trade cost?\n feeMaker: 0.5,\n feeTaker: 0.6,\n // Using taker or maker fee?\n feeUsing: 'maker',\n // how much slippage should Gekko assume per trade?\n slippage: 0.1\n }\n\n- enabled indicates whether this is on or off.\n- reportInCurrency tells Gekko whether it should report in asset or in the currency.\n- simulationBalance tells Gekko with what balance it should start.\n- verbose specifies how often Gekko should log the results (false is after every trade, true is after every candle).\n- fee is the exchange fee (in %) Gekko should take into consideration when simulating orders.\n- slippage is the costs in (in %) associated with not being able to buy / sell at market price.*\n\n*If you are trading a lot and you are buying 100% currency you might not get it all at market price and you have to walk the book in order to take that position. Also note that Gekko uses the candle close price and is unaware of the top asks bids, also take this into account. It is important that you set this number correctly or the resulted calculated profit be very wrong. Read more information [here](http://www.investopedia.com/terms/s/slippage.asp). Take these into consideration when setting a slippage:\n\n- How much spread is there normally on this market?\n- How thick is the top of the book normally?\n- How volatile is this market (the more volatility the bigger the chance you will not get the price you expected)?\n\nThe output will be something like:\n\n 2013-06-02 18:21:15 (INFO): ADVICE is to SHORT @ 117.465 (0.132)\n 2013-06-02 18:21:15 (INFO): (PROFIT REPORT) original balance: 207.465 USD\n 2013-06-02 18:21:15 (INFO): (PROFIT REPORT) current balance: 217.465 USD\n 2013-06-02 18:21:15 (INFO): (PROFIT REPORT) profit: 10.000 USD (4.820%)\n\n### Mailer\n\nMailer will automatically email you whenever Gekko has a new advice.\n\n // want Gekko to send a mail on buy or sell advice?\n config.mailer = {\n enabled: false, // Send Emails if true, false to turn off\n sendMailOnStart: true, // Send 'Gekko starting' message if true, not if false\n\n Email: 'me@gmail.com', // Your GMail address\n\n // You don't have to set your password here, if you leave it blank we will ask it\n // when Gekko's starts.\n //\n // NOTE: Gekko is an open source project < https://github.com/askmike/gekko >,\n // make sure you looked at the code or trust the maintainer of this bot when you\n // fill in your email and password.\n //\n // WARNING: If you have NOT downloaded Gekko from the github page above we CANNOT\n // guarantee that your email address & password are safe!\n\n password: '', // Your GMail Password - if not supplied Gekko will prompt on startup.\n tag: '[GEKKO] ' // Prefix all EMail subject lines with this\n }\n\n- enabled indicates whether this is on or off.\n- sendMailOnStart will email you right away after Gekko started, you can also use this if you are automatically restarting Gekko to see crash behaviour.\n- Email is your email address from which Gekko will send emails (to the same address).\n- password is the email password: Gekko needs to login to your account to send emails to you:\n\n > You don't have to set your password here, if you leave it blank we will ask it\n > when Gekko's starts.\n >\n > NOTE: Gekko is an open source project < https://github.com/askmike/gekko >,\n > make sure you looked at the code or trust the maintainer of this bot when you\n > fill in your email and password.\n >\n > WARNING: If you have NOT downloaded Gekko from the github page above we CANNOT\n > guarantee that your email address & password are safe!\n\n- tag is some text that Gekko will put in all subject lines so you can easily group all advices together.\n\n### IRC bot\n\nIRC bot is a small plugin that connects Gekko to an IRC channel and lets users interact with it using basic commands.\n\n config.ircbot = {\n enabled: false,\n emitUpdates: false,\n channel: '#your-channel',\n server: 'irc.freenode.net',\n botName: 'gekkobot'\n }\n\n- enabled indicates whether this is on or off.\n- emitUpdates tells Gekko that whenever there is a new advice it should broadcast this in the channel.\n- channel is the IRC channel the bot will connect to.\n- server is the IRC server.\n- botName is the username Gekko will use.\n\n### Campfire bot\n\nCampfire bot is a small plugin that connects Gekko to a Campfire room and lets users interact with it using basic commands.\n\n config.campfire = {\n enabled: false,\n emitUpdates: false,\n nickname: 'Gordon',\n roomId: 673783,\n apiKey: 'e3b0c44298fc1c149afbf4c8996',\n account: 'your-subdomain'\n }\n\n- enabled indicates whether this is on or off.\n- emitUpdates tells Gekko that whenever there is a new advice it should broadcast this in the room.\n- roomId is the ID of the Campfire room the bot will connect to.\n- apiKey is the API key for the Campfire user Gekko will connect using.\n- account is the subdomain for the account that the room belongs to.\n\n### Redis beacon\n\nThis is an advanced plugin only for programmers!

Don't forget to create a pull request of the awesome plugin you've just created!\n" }, { "path": "docs/extending/add_an_exchange.md", "content": "# Exchanges\n\n*This is a technical document about adding a new exchange to Gekko and Gekko Broker.*\n\nGekko arranges all communication about when assets need to be bought or sold between the *strategy* and *Gekko Broker*. All differences between the different API's are abstracted away just below Gekko Broker inside an \"exchange wrapper\". This document describes all requirements for adding a new exchange wrapper (adding exchange support to Gekko).\n\nWhen you add a new exchange to Gekko you need to expose an object that has methods to query the exchange. This exchange file needs to reside in `gekko/exchange/wrappers` and the filename is the slug of the exchange name + `.js`. So for example the exchange integration with Binance is explained in `gekko/exchange/wrappers/binance.js`.\n\nPlease use a npm module to query an exchange. This will separate the abstract API calls from the Gekko specific stuff (In the case of Bitstamp there was no module yet, so I [created one](https://www.npmjs.com/package/bitstamp)).\n\nFinally Gekko needs to know how it can interact with the exchange, so add a static method `getCapabilities()` that returns it's properties. They are all described [here](#capabilities).\n\n## Gekko's expectations\n\nGekko Broker implements an exchange like so:\n\n const Exchange = require('./wrapper' + [exchange slug]);\n this.exchange = new Exchange({key: '', secret: '', username: '', currency: 'USD', asset: 'BTC'});\n\nIt will run the following methods on the exchange object:\n\n### getTrades\n\nWith this single method implemented Gekko won't be able to do live trading, but it will be able to do paper trading and storing market data for backtesting.\n\n this.watcher.getTrades(since, callback, descending);\n\nIf since is truthy, Gekko requests as much trades as the exchange can give (up to ~10,000 trades, if the exchange supports more you can [create an importer](../features/importing.md)).\n\nThe callback expects an error and a `trades` object. Trades is an array of trade objects in chronological order (0 is older trade, 1 is newer trade). Each trade object needs to have:\n\n- a `date` property (unix timestamp in either string or int)\n- a `price` property (float) which represents the price in [currency] per 1 [asset].\n- an `amount` property (float) which represent the amount of [asset].\n- a `tid` property (float) which represents the tradeID.\n\n## Gekko Broker's expectations\n\nThe methods below are needed for Gekko to automatically trade on the exchange.\n\n### getTicker\n\n this.exchange.getTicker(callback)\n\nThe callback needs to have the parameters of `err` and `ticker`. Ticker needs to be an object with at least the `bid` and `ask` property in float.\n\n### getFee\n\n this.exchange.getFee(callback);\n\nThe callback needs to have the parameters of `err` and `fee`. Fee is a float that represents the amount the exchange takes out of the orders Gekko places. If an exchange has a fee of 0.2% this should be `0.002`.\n\n### getPortfolio\n\n this.exchange.getPortfolio(callback);\n\nThe callback needs to have the parameters of `err` and `portfolio`. Portfolio needs to be an array of all currencies and assets combined in the form of objects, an example object looks like `{name: 'BTC', amount: 1.42131}` (name needs to be an uppercase string, amount needs to be a float).\n\n### getLotSize\n\n this.exchange.getLotSize(tradeType, amount, size, callback);\n\nThe callback needs to have the parameters of `err` and `lot`. Lot needs to be an object with `amount` and `purchase` size appropriately for the exchange. In the event that the lot is too small, return 0 to both fields and this will generate a lot size warning in the portfolioManager.\n\nNote: This function is currently optional. If not implemented Gekko Broker will fallback to basic lot sizing mechanism it uses internally. However exchanges are not all the same in how rounding and lot sizing work, it is recommend to implement this function.\n\n### buy\n\n this.exchange.buy(amount, price, callback);\n\n### sell\n\n this.exchange.sell(amount, price, callback);\n\nThis should create a buy / sell order at the exchange for [amount] of [asset] at [price] per 1 asset. The callback needs to have the parameters `err` and `order`. The order needs to be some id that can be passed back to `checkOrder`, `getOrder` and `cancelOrder`.\n\n### getOrder\n\n this.exchange.getOrder(order, callback);\n\nWill only be called on orders that have been completed. The order will be something that the manager previously received via the `sell` or `buy` methods. The callback should have the parameters `err` and `order`. Order is an object with properties `price`, `amount` and `date`. Price is the (volume weighted) average price of all trades necessary to execute the order. Amount is the amount of currency traded and Date is a moment object of the last trade part of this order.\n\n### checkOrder\n\n this.exchange.checkOrder(order, callback);\n\nThe order will be something that the manager previously received via the `sell` or `buy` methods. The callback should have the parameters `err` and a `result` object. The result object will have two or three properties:\n\n- `open`: whether this order is currently in the orderbook.\n- `executed`: whether this order has executed (filled completely).\n- `filledAmount`: the amount of the order that has been filled. This property is only needed when both `open` is true and `completed` is false.\n\n### cancelOrder\n\n this.exchange.cancelOrder(order, callback);\n\nThe order will be something that the manager previously received via the `sell` or `buy` methods. The callback should have the parameters `err`, `filled` and optionally a `fill` object, `filled` should be true if the order was fully filled before it could be cancelled. If the exchange provided how much was filled before the cancel this should be passed in the `fill object` as a `amountFilled` property. If the exchange provided how much of the original amount is still remaining, pass this as the `remaining` property instead.\n\n### roundPrice\n\n this.exchange.roundPrice(rawPrice);\n\nShould return a price. Rounds the price into a valid price Gekko Broker can later feed into a buy or sell order. *Note: if representation of the number is important for the exchange (for example if the exchange will not accept numbers expressed in scientific notation) you can return a string from this method (Gekko Broker will perform calculations so the string should be castable to a number.)* \n\n### roundAmount\n\n this.exchange.roundAmount(rawAmount);\n\nShould return an amount. Rounds the amount into a valid amount Gekko Broker can later feed into a buy or sell order. *Note: if representation of the number is important for the exchange (for example if the exchange will not accept numbers expressed in scientific notation) you can return a string from this method (Gekko Broker will perform calculations so the string should be castable to a number.)*\n\n## Gekko Broker's optional methods\n\n### isValidPrice\n\n this.exchange.isValidPrice(price);\n\nShould return true or false. If the exchange has restrictions on the price you can submit limit orders at. If there are no such restrictions you should not implement this method.\n\n### isValidLot\n\n this.exchange.isValidLot(price, amount);\n\nShould return true or false. If the exchange has restrictions on the lot size (order size expressed in \"currency\" amount) you can check for that here. If there are no such restrictions you should not implement this method.\n\n## Error handling\n\nIt is the responsibility of the wrapper to handle errors and retry the call in case of a temporary error. Gekko exposes a retry helper you can use to implement an exponential backoff retry strategy. Your wrapper does need pass a proper error object explaining whether the call can be retried or not. If the error is fatal (for example private API calls with invalid API keys) the wrapper is expected to upstream this error. If the error is retryable (exchange is overloaded or a network error) an error should be passed with the property `notFatal` set to true. If the exchange replied with another error that might be temporary (for example an `Insufficient funds` error right after Gekko canceled an order, which might be caused by the exchange not having updated the balance yet) the error object can be extended with an `retry` property indicating that the call can be retried for n times but after that the error should be considered fatal.\n\nFor implementation refer to the bitfinex implementation, in a gist this is what a common flow looks like:\n\n- (async call) `exchange.buy`, then\n- handle the response and normalize the error so the retry helper understands it, then\n- the retry helper will determine whether the call needs to be retried, then\n - based on the error it will retry (for example `nonFatal` or `retry`)\n - if no error it will pass it to your handle function that normalizes the output\n\n## Capabilities\n\nEach exchange *must* provide a `getCapabilities()` static method that returns an object with these parameters:\n\n- `name`: Proper name of the exchange\n- `slug`: slug name of the exchange (needs to match filename in `gekko/exchanges/`)\n- `currencies`: all the currencies supported by the exchange implementation in gekko.\n- `assets`: all the assets supported by the exchange implementation in gekko.\n- `pairs`: all allowed currency / asset combinations that form a market\n- `maxHistoryFetch`: the parameter fed to the getTrades call to get the max history.\n- `providesHistory`: If the getTrades can be fed a since parameter that Gekko can use to get historical data, set this to:\n - `date`: When Gekko can pass in a starting point in time to start returning data from.\n - `tid`: When Gekko needs to pass in a trade id to act as a starting point in time.\n - `false`: When the exchange does not support to give back historical data at all.\n- `fetchTimespan`: if the timespan between first and last trade per fetch is fixed, set it here in minutes.\n- `tradable`: if gekko supports automatic trading on this exchange.\n- `requires`: if gekko supports automatic trading, this is an array of required api credentials gekko needs to pass into the constructor.\n- `forceReorderDelay`: if after canceling an order a new one can't be created straight away since the balance is not updated fast enough, set this to true (only required for exchanges where Gekko can trade).\n- `gekkoBroker`: set this to \"0.6.2\" for now, it indicates the version of Gekko Broker this wrapper is compatible with.\n- `limitedCancelConfirmation` set to true if (in any case) the wrapper does NOT include partial fill information in the response (which is passed as the cancel callback)\n\nBelow is a real-case example how `bistamp` exchange provides its `getCapabilities()` method:\n\n```\nTrader.getCapabilities = function () {\n return {\n name: 'Bitstamp',\n slug: 'bitstamp',\n currencies: ['USD', 'EUR'],\n assets: ['BTC', 'EUR'],\n maxTradesAge: 60,\n maxHistoryFetch: null,\n markets: [\n { pair: ['USD', 'BTC'], minimalOrder: { amount: 1, unit: 'currency' } },\n { pair: ['EUR', 'BTC'], minimalOrder: { amount: 1, unit: 'currency' } },\n { pair: ['USD', 'EUR'], minimalOrder: { amount: 1, unit: 'currency' } }\n ],\n requires: ['key', 'secret', 'username'],\n fetchTimespan: 60,\n tid: 'tid',\n gekkoBroker: '0.6.2',\n limitedCancelConfirmation: false\n };\n}\n```\n" }, { "path": "docs/extending/other_software.md", "content": "# Other Software\n\nSince Gekko version 0.4 Gekko can launch a process which exposes a web (REST and Websocket) API that can be used to control Gekkos (start a backtest, start a running Gekko, etc).

A Backtest is a simulation where you simulate running a strategy over a long time (such as the last 30 days) in a matter of seconds. Backtesting requires having market data locally available already. After a backtest Gekko will provide statistics about the market and the strategy's performance.\n\n![screen shot of gekko backtesting](https://cloud.githubusercontent.com/assets/969743/24838718/8c790a86-1d45-11e7-99ae-e7e551cb40cb.png)\n\n**Important things to remember:**\n\n- Just because a strategy performed well in the past, does not mean it will perform well in the future.\n- Be careful of overfitting, in other words: don't simply tweak a strategy until you get high profit and assume that will be as profitable when going live. Read more about overfitting in [this article](https://laplaceinsights.com/backtesting-strategies-and-overfitting/).\n- The backtest simulation is limited, this is not really a problem on bigger markets (such as BTC/USD) but the differences between backtests and live traders on very low volume markets might be big. Read more about this below in the simplified simulation below.\n\n## Simplified simulation\n\nSimulating trades is done through a module called the paper trader. This module will use market candles together with fee, slippage and spread numbers to estimate trade executions costs. While the default settings work great for most big markets (USD/BTC or BTC/ETH), it becomes a lot less acurate on smaller markets with low volume and liquidity.\n\nIn live trading the notion of the \"price\" is more complicated than a single number. Both `spread` and `slippage` will effect your trade prices: these numbers describe your desired trades in relation to what people are currently offering in the market (this is called the orderbook). Read more about this in [this explanation](https://github.com/askmike/gekko/issues/2380#issuecomment-408744682).\n\nIf you look at the following backtest result:\n\n![screen shot of backtesting at an illiquid market](https://cloud.githubusercontent.com/assets/969743/24840243/8f307022-1d61-11e7-9964-e6614d7433ea.png)\n\nYou can see a lot of \"spikes\" of the price moving up and down. These are not actually price fluctuations but simply trades that happen on both sides of the orderbook (a bid is taken then an ask is taken). How far it jumps up and down is the spread (between the asks and the bids). In these cases the statistics from the simulation won't be very accurate (unless you configured a higher slippage to account for the spread). This is unfortunately a limitation in Gekko's backtesting model.\n" }, { "path": "docs/features/importing.md", "content": "# Importing\n\nIn order to [backtest](./backtesting.md) your strategies you will need to have historical market data to test with.

See the complete list [here](https://gekko.wizb.it/docs/introduction/supported_exchanges.html).\n\nThis library allows you to:\n\n- Get basic market data\n - ticker (BBO)\n - ~orderbook~ (TODO)\n - historical trades\n- Get portfolio data\n- Do an (advanced) order:\n - Submit the order to the exchange\n - Receive events about the status of the order:\n - submitted\n - open (accepted)\n - partially filled\n - rejected\n - completed\n - Mutate the order\n - cancel\n - amend\n - move\n - move limit\n- Tracks orders submitted through the library.\n\n## Status\n\nEarly WIP. All communication is via the REST APIs of exchanges. Not all exchanges are supported, see which ones are in [this doc](../introduction/supported_exchanges.md).\n\n## Order types\n\nThis library aims to offer advanced order types, even on exchanges that do not natively support them by tracking the market and supplementing native order support on specific exchanges.\n\nWorking:\n\n- Base orders\n - [Sticky Order](./sticky_order.md)\n\nTODO:\n\n- Base orders:\n - Limit Order\n - Market Order\n- Triggers:\n - Stop\n - If Touched (stop but opposite direction)\n\n### Example\n\nSet up a Gekko Broker instance:\n\n // from the gekko repo (make sure you have deps installed\n // inside the exchange folder).\n const Broker = require('../gekko/exchange/GekkoBroker');\n // or from NPM\n // const Broker = require('gekko-broker');\n\n const binance = new Broker({\n currency: 'USDT',\n asset: 'BTC',\n private: true,\n\n exchange: 'binance',\n key: 'x', // add your API key\n secret: 'y' // add your API secret\n });\n\nNow we have an instance that can create a [sticky order](./sticky_order.md):\n\n const type = 'sticky';\n const side = 'buy';\n const amount = 1;\n\n const order = binance.createOrder(type, side, amount);\n\n order.on('statusChange', s => console.log(now(), 'new status', s));\n order.on('fill', s => console.log(now(), 'filled', s));\n order.on('error', s => console.log(now(), 'error!', e));\n order.on('completed', a => {\n console.log(new Date, 'completed!');\n order.createSummary((err, s) => {\n console.log(new Date, 'summary:');\n console.log(JSON.stringify(s, null, 2));\n });\n });\n\nThis one doesn't have an upper limit price for what it will buy at. It will stick it's bid offer at BBO until it's filled. If you have a limit in mind you can specify it when creating, do this instead:\n\n const order = binance.createOrder(type, side, amount, { limit: 100 });\n\nIt will never offer to buy for more than 100, even if the BBO is above 100 (the bid will end up deep in the book).\n\nAt any point in time you can change the limit (or the amount), for example:\n\n order.moveLimit(120);\n\nRunning the above example (without setting a limit and moving it) will yield:\n\n root@foxtail:~/gb/nusadua# node b\n 2018-07-29 03:46:02 new status SUBMITTED\n 2018-07-29 03:46:02 new status OPEN\n 2018-07-29 03:46:04 filled 1\n 2018-07-29 03:46:04 new status FILLED\n 2018-07-29T03:46:04.127Z 'completed!'\n 2018-07-29T03:46:04.358Z 'summary:'\n {\n \"price\": 0.0017479,\n \"amount\": 1,\n \"date\": \"2018-07-29T03:46:02.576Z\",\n \"side\": \"buy\",\n \"orders\": 1,\n \"fees\": {\n \"BNB\": 0.00075\n },\n \"feePercent\": 0.075\n }\n\nNOTE: not all status changes are documented and more events are planned but not implemented.\n\n### TODO\n\n- finish all exchange integrations that gekko supports\n- finish all order types and triggers (under todo)\n- implement websocket support (per exchange)\n- use native move API calls wherever possible (poloniex)\n" }, { "path": "docs/gekko-broker/sticky_order.md", "content": "# Sticky Order\n\nAn advanced order that stays at the top of the book (until the optional limit).

Unless you are running in a completely trusted network (home network) you WILL need to get an SSL certificate, upstream Gekko through a webserver, etc. I am creating an official Gekko service called [Gekko Plus](https://gekkoplus.com/) that will NOT require any of this stuff.*\n\nGekko runs great headless (on a server, raspberry PI) but the default configuration assumes that you will be using a browser from the same machine to access the interface.\n\n# Installation\n\nPlease see the normal [installing gekko](./installing_gekko.md) document, but before starting gekko please update the configuration as stated below:\n\n# Configuring Gekko\n\nIn order to setup Gekko so that you can access it remotely you need to open and edit the following file: `gekko/web/vue/dist/UIconfig.js`. You need to configure this file according to your use case:\n\n- You want to Gekko headless in a trusted environment (eg. on a raspberry pi or old laptop in your home network) - [see here](#configuring-gekko-to-run-headless-in-a-trusted-environment).\n- You want to run Gekko in the cloud on a server - [see here](#configuring-gekko-to-run-in-the-cloud).\n\n## Configuring Gekko to run headless in a trusted environment\n\nEdit the uiconfig file like so:\n\n const CONFIG = {\n headless: true,\n api: {\n host: '0.0.0.0',\n port: 3000,\n },\n ui: {\n ssl: false,\n host: 'x.x.x.x', // Set this to the IP of the machine that will run Gekko\n port: 3000,\n path: '/'\n },\n adapter: 'sqlite'\n\n }\n\nYou can now access the Gekko UI by going to `http://x.x.x.x:3000` in a browser (change `x.x.x.x` with the IP of the machine that will run Gekko).\n\n\n## Configuring Gekko to run in the cloud\n\nImportant note: if you expose Gekko to the open internet (or on any non trusted network) you are recommended to put a secure reverse proxy (for example with both [SSL](#Obtaining-a-SSL-certificate) and [BasicAuth](#Create-htpasswd-for-basic-password-authentication)) in front of it. While we believe Gekko is hard to exploit, it allows for 24/7 backtesting which will drain your machine's resources (possible DoS).\n\nThe following assumes you configured a reverse proxy, if you did not simply follow [these instructions](#Configuring-NGINX-as-a-reverse-proxy) to do so.\n\n\n const CONFIG = {\n headless: true,\n api: {\n host: '127.0.0.1',\n port: 3000,\n },\n ui: {\n ssl: true,\n host: 'gekko.example.com',\n port: 443,\n path: '/' // change this if you are serving from something like `example.com/gekko`\n },\n adapter: 'sqlite'\n }\n\n\n## Configuring NGINX as a reverse proxy\n\nNGINX is a highly configurable, lightweight, yet easily deployed webserver allowing features such as a reverse proxying using secure sockets layer with authentication and much more.\n\nInstalling NGINX using your Operating Systems package manager of choice is pretty straight forward. For Debian Linux it is a simple sudo apt-get install nginx\n\nOnce NGINX is installed you will need to modify the configuration file. For Debian Linux the config is located at /etc/nginx/sites-enabled/default\n\n server {\n listen 80;\n listen [::]:80;\n server_name gekko.example.com;\n return 301 https://$server_name$request_uri;\n }\n\n upstream websocket {\n server localhost:3000;\n }\n\n server {\n listen 443 ssl;\n listen [::]:443 ssl;\n root /var/www/html;\n\n ssl_certificate /etc/nginx/ssl/nginx.crt;\n ssl_certificate_key /etc/nginx/ssl/nginx.key;\t\n\n location / {\n proxy_buffers 8 32k;\n proxy_buffer_size 64k;\n\n proxy_pass http://websocket;\n proxy_set_header X-Real-IP $remote_addr;\n proxy_set_header Host $http_host;\n proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;\n proxy_set_header X-NginX-Proxy true;\n\n proxy_http_version 1.1;\n proxy_set_header Upgrade $http_upgrade;\n proxy_set_header Connection \"upgrade\";\n\n proxy_read_timeout 86400s;\n proxy_send_timeout 86400s;\n\n auth_basic \"Restricted Content\";\n auth_basic_user_file /etc/nginx/.htpasswd;\n }\n }\n\n\n## Obtaining a SSL certificate\n\nYour OS may or may not ship with openssl preinstalled. In the case it doesn't, simply install openssl using your package manager of choice. eg: `sudo apt-get install openssl`.\n\nBelow you can choose between creating a self signed certificate useful if you do not have a fqdn (fully qualified domain name), or if you by chance do have a fqdn you can use certbot to obtain a Let's Encrypt CA signed certificate.\n\n\n### To create a self signed certificate:\n\n sudo mkdir /etc/nginx/ssl\n sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /etc/nginx/ssl/nginx.key -out /etc/nginx/ssl/nginx.crt\n\n\n### To obtain a Let's Encrypt CA signed certificate:\n\nInstall certbot, a client to obtain signed ssl certificates for your domain.\n\n sudo apt-get install certbot\n\nRun the following command:\n\n certbot certonly --standalone -d example.com -d gekko.example.com\n\nModify your NGINX config and replace the ssl lines with the following:\n\n ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem;\n ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem;\n add_header Strict-Transport-Security \"max-age=31536000\";\n\n\n## Create htpasswd for basic password authentication\n\nChange username to desired username and enter password when prompted:\n\n printf \"username:`openssl passwd -apr1`\\n\" >> /etc/nginx/.htpasswd\n" }, { "path": "docs/installation/installing_gekko.md", "content": "# Installing Gekko\n\n*NOTE: unfortunately installing and managing Gekko is hard.

Go ahead and install this if it's not already (Gekko requires at least version 8.11.2). We advice to download the current LTS.\n\n## Installing git\n\nAs part of Gekko's installation process git is used, see [this guide](https://www.linode.com/docs/development/version-control/how-to-install-git-on-linux-mac-and-windows/) for installation instructions. If you do not already have git on your system.\n\n## Downloading Gekko\n\nThe recommended way of downloading Gekko is by using git. This makes keeping Gekko up to date a lot easier. Run this in a terminal:\n\n git clone git://github.com/askmike/gekko.git -b stable\n cd gekko\n\nThis will download the latest stable version of Gekko, remove the final `-b stable` part to download the current latest release (which might not be as stable).\n\nAlternatively you can manually download the latest stable version of Gekko on the [releases page](https://github.com/askmike/gekko/releases).\n\n## Installing Gekko's dependencies\n\nOnce you have Gekko downloaded you need to install the dependencies, open your terminal and navigate to the gekko folder and run:\n\n npm install --only=production\n\n*NOTE: You may see a vulnerability warning from NPM, if you run npm audit with --force, Gekko will break. See [here](https://github.com/askmike/gekko/issues/2585#issuecomment-428450997).*\n\nYou also need to install Gekko Broker's dependencies, run:\n\n cd exchange\n npm install --only=production\n cd ..\n\n## Starting Gekko\n\nAfter all the above you can start Gekko by running the following in your terminal:\n\n node gekko --ui\n\n## Updating Gekko\n\nSee the [updating Gekko](./updating_gekko.md) doc.\n" }, { "path": "docs/installation/installing_gekko_on_raspberry_pi_2_or_3.md", "content": "# Installing Gekko on Raspberry Pi 2 or 3\n\nThis manual is intended for a Raspberry Pi 2 or 3 with freshly installed Raspbian Stretch (Lite).\n\nTo get Gekko running on your Pi you need to do the following:\n\n- update your package lists\n- install nodejs\n- download Gekko\n- install Gekko's dependencies\n- (optional) Configure your Pi as a headless server in your local network\n\n## Update your package lists\n\n sudo apt-get update\n sudo apt-get upgrade\n\n## Installing nodejs\n\nWe recommend installing the latest LTS Version of Node, currently 8.x.x\n\n curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash -\n sudo apt-get install -y nodejs\n\nImportant: Ignore the errors!\n=> It automatically builds from source instead, it can take over 10 minutes!

The Market implements a Readable Stream interface while the GekkoStream implements a Writeable Stream interface.\n\n## A Market\n\nAll markets in Gekko eventually output `candle` data. Where these candles come from and how old they are does not matter to the GekkoStream they get piped into. On default Gekko looks for markets in the [`core/markets/` directory](https://github.com/askmike/gekko/tree/stable/core/markets). The top orange block in the picture is a BudFox market (the default semi-realtime market that gets live data from exchanges).\n\nExample Markets that come included with Gekko are:\n\n- **BudFox** (a realtime market): this market stays on indefinitely and outputs candles from the live markets in semi-realtime (cryptocurrency exchanges run 24/7).\n- **backtest**: this market reads candles from a database and outputs them as fast as the GekkoStream is able to consume them (the GekkoStream will run TA strategies over these candles).\n- **importer**: the importer market will fetch historical data from an exchange and pass on (to the GekkoStream who inserts them in a database).\n\n## A GekkoStream\n\nA GekkoStream is nothing more than a collection of [plugins](../commandline/plugins.md). Plugins are simple modules that can subscribe to events, and do something based on event data. The most basic event every GekkoStream has is the \"candle\" event, this event comes from the market.\n\nHowever **plugins are allowed to broadcast their own events, which other plugins can subscribe to**. An example of this is the `tradingAdvisor` plugin. This plugin will implement a [strategy](../strategies/introduction.md) that will be fed candle data. As soon as the strategy suggests to take a certain position in the market (\"I detect an uptrend, I advice to go **long**\") it will broadcast an `advice` event. The `paperTrader` is a plugin that simulates trading using these advices, the `trader` is a plugin that creates real market orders based on these advices. You can decide to only turn the `paperTrader` on or to turn the `trader` on (you now have a live trading bot).\n\nWhen you run a backtest using Gekko the following things happen:\n\n- Gekko configures a `backtest` market.\n- Gekko loads all configured plugins that are supported in the `backtest` mode* into a GekkoStream.\n- Gekko pipes the market into the GekkoStream and voila!\n\n\\*Gekko refuses to load plugins that are unsupported in specific modes. During backtests you **never** want to enable the real trader to enter market orders. Because if you would the advice would be based on specific moments in the backtest, not on the current state of the market.\n\n## Plugins & Adapters\n\nThose two core components describe the majority of Gekko's flow. A lot \"core functionality\" like saving candles to disk are simply plugins that push all candles to a database.\n\n## Separated architecture\n\nThe modular nature of Gekko makes it very dynamic and allows for rapidly creating new plugins. However there is an ugly side to this story:\n\nThe `tradingAdvisor` runs TA strategies against a market. The problem however is that most TA indicators need some history before they can give accurate results. If you want to use an EMA (exponential moving average), you need some history to base the initial average on. But because the tradingAdvisor doesn't know what market data is going to be made available later by the market, it needs to do some fetching itself and compare that to locally available market data (stored in the local database) to see if it can stitch the two sources.\n" }, { "path": "docs/internals/budfox.md", "content": "# BudFox\n\n**Similar to the [movie Wallstreet](https://en.wikipedia.org/wiki/Wall_Street_(1987_film)), Gekko delegates the dirty work of getting fresh data to Bud Fox. Bud Fox delivers the data to Gekko who uses this data to make investment decisions.**\n\nWhenever Gekko works with realtime market data, it spawns a BudFox to fetch and transform the data for every market (exchange + asset + pair, for example: `bitstamp USD/BTC`). Bud Fox will keep on fetching data from the market in semi-realtime, turn historical trades into minutely candles (and make sure every minute of data has a candle).\n\nBudFox exposes a stream of `candles` which are fed to Gekko.\n\n## Advanced Usage\n\nBudFox is a small part of Gekko's core that aggregates realtime market data from any supported exchange into a readable stream of candles. Example usage:\n\n var config = {\n exchange: 'Bitstamp',\n currency: 'USD',\n asset: 'BTC'\n }\n\n new BudFox(config)\n .start()\n // convert JS objects to JSON string\n .pipe(new require('stringify-stream')())\n // output to standard out\n .pipe(process.stdout);\n\nOutputs:\n\n {\"start\":\"2015-02-02T23:08:00.000Z\",\"open\":238.21,\"high\":239.35,\"low\":238.21,\"close\":238.66,\"vwp\":8743.778447997309,\"volume\":203.6969347,\"trades\":56}\n {\"start\":\"2015-02-02T23:09:00.000Z\",\"open\":239.03,\"high\":240,\"low\":238.21,\"close\":239.19,\"vwp\":8725.27119145289,\"volume\":323.66383462999994,\"trades\":72}\n {\"start\":\"2015-02-02T23:10:00.000Z\",\"open\":239.19,\"high\":239.8,\"low\":234.68,\"close\":235,\"vwp\":6664.509955946812,\"volume\":114.67727173,\"trades\":48}\n {\"start\":\"2015-02-02T23:11:00.000Z\",\"open\":237.77,\"high\":238.51,\"low\":235,\"close\":238.1,\"vwp\":3158.835462414369,\"volume\":41.47081054999999,\"trades\":28}\n {\"start\":\"2015-02-02T23:12:00.000Z\",\"open\":237,\"high\":238,\"low\":236.78,\"close\":237.9,\"vwp\":1634.5173557116634,\"volume\":70.58755061,\"trades\":22}\n {\"start\":\"2015-02-02T23:13:00.000Z\",\"open\":237.95,\"high\":238.49,\"low\":237.95,\"close\":238.49,\"vwp\":604.219141331534,\"volume\":12.196531389999999,\"trades\":7}\n {\"start\":\"2015-02-02T23:14:00.000Z\",\"open\":238.51,\"high\":241,\"low\":237.89,\"close\":241,\"vwp\":7610.305142999085,\"volume\":579.5321983399998,\"trades\":67}\n {\"start\":\"2015-02-02T23:15:00.000Z\",\"open\":238.12,\"high\":239.76,\"low\":238.12,\"close\":239.1,\"vwp\":1828.5872875471068,\"volume\":31.16232463,\"trades\":17}\n {\"start\":\"2015-02-02T23:16:00.000Z\",\"open\":239.1,\"high\":239.76,\"low\":239.1,\"close\":239.67,\"vwp\":1339.3753800771717,\"volume\":5.56431998,\"trades\":12}\n {\"start\":\"2015-02-02T23:17:00.000Z\",\"open\":239.27,\"high\":239.99,\"low\":239.25,\"close\":239.92,\"vwp\":1519.3392752690336,\"volume\":6.984999999999999,\"trades\":14}\n {\"start\":\"2015-02-02T23:18:00.000Z\",\"open\":239.92,\"high\":239.98,\"low\":238.98,\"close\":238.98,\"vwp\":4162.807256131301,\"volume\":21.17212333,\"trades\":29}\n {\"start\":\"2015-02-02T23:19:00.000Z\",\"open\":239,\"high\":239,\"low\":238.15,\"close\":238.33,\"vwp\":1627.2581467076204,\"volume\":31.682705360000003,\"trades\":15}\n {\"start\":\"2015-02-02T23:20:00.000Z\",\"open\":238.33,\"high\":239.95,\"low\":238.33,\"close\":239,\"vwp\":3648.661808492067,\"volume\":128.35564560999998,\"trades\":23}\n // etc..\n" }, { "path": "docs/internals/events.md", "content": "# Events\n\nAs described in the [architecture](./architecture.md) events play a key role in the complete system: they relay all information between separate components (like [plugins](./plugins.md)).

The server API documentation can be found [here](./server_api.md).\n\n## Gekko UI Frontend\n\nThe frontend is setup as a very basic vue app. Additionally the following libraries are used:\n\n- [Reconnecting websocket](https://github.com/joewalnes/reconnecting-websocket)\n- [Moment](http://momentjs.com/)\n- [d3.js](https://d3js.org/)\n- [toml](https://github.com/BinaryMuse/toml-node)\n- [humanizeDuration](https://github.com/EvanHahn/HumanizeDuration.js)\n\nThe vue app itself uses the following libraries:\n\n- [marked](https://github.com/chjj/marked)\n- [pug](https://github.com/pugjs) (all html is either written in pug of markdown)\n- [vue-router](https://github.com/vuejs/vue-router)\n- [vuex](https://github.com/vuejs/vuex)\n- [superagent](https://github.com/visionmedia/superagent) (cross browser ajax)\n\n### Developing for the Gekko UI frontend\n\nYou first need to install all developer dependencies so the frontend app can be recompiled on your machine.\n\n cd gekko/web/vue\n npm install\n\nAfter this you can launch a hot reload version of the app which will automatically recompile the frontend and reload your browser:\n\n # path to webserver\n cd gekko/web\n # launch the server - we use this API\n node server\n\n # path to vue app\n cd vue\n npm run serve\n\nGekko UI is now served from port 8080, the webpack dev server will compile the vue app (in memory) and intercept all calls to the app itself (`/dist/js/app.xxx.js`) and serve the in memory app. It is important to note that this UI still talks to the API served from the `node server` command (on default http://localhost:3000/api).\n\n\nIf you have configured Gekko to run on non standards ports (using the UIconfig), you can have your config applied to the development environment by copying `gekko/web/vue/dist/UIconfig.js` to `gekko/web/vue/public/UIconfig.js`.\n\n### Compiling the Gekko UI frontend\n\n*Note: as part of the compilation process Gekko will reset the UIconfig in both `gekko/web/vue/dist/UIconfig.js` and `gekko/web/vue/public/UIconfig.js`. Only compile if you are ready to lose your personal changes.*\n\nWhen you are done developing you can compile the app using these instructions:\n\n # path to vue app\n cd gekko/web/vue\n npm run build\n" }, { "path": "docs/internals/plugins.md", "content": "# Plugins\n\n*This is a technical document explaining the role of Plugins in the Gekko codebase. For a non technical document about available plugins, see [here](../commandline/plugins.md).*\n\nWithin Gekko most functionality is encapsulated into \"plugins\". These are simple modules that process some data (from [Gekko events](./events.md)) and do something with it. For example emitting a new event or sending a message out to some external service like telegram, or doing a live trade at an exchange.\n\nWhenever you run a Gekko (live trader, paper trader, backtester or importer) you are simply running a number of plugins and feeding them with market data. For a more detailed explanation, see the [architecture doc](./architecture.md).\n\nFor example, there is a plugin called the paperTrader which is responsible for simulating trades (used in [backtests](../features/backtesting.md) and [paper trading](../features/paper_trading.md)). It does this by listening to advice events coming from a strategy, and simulating trades whenever they fire (and firing trade events). Find a longer list of plugins that come with Gekko [here](../commandline/plugins.md).\n\n- All plugins are javascript files that expose a constructor function (or ES6 class).\n- All plugins are stored in `gekko/plugins`.\n- All plugins are described in the file [`gekko/plugins.js`](https://github.com/askmike/gekko/blob/develop/plugins.js), this way Gekko knows how/when the plugin can be used (for example it does not make sense to run a telegram bot that will emit all trades in a backtest).\n\n## Structure of a plugin\n\nA plugin can be a very simple module that simply listens to some event:\n\n\n // A plugin that will buy Champagne when we MOON\n\n // example: doesn't actually work..\n const alexa = require('alexa');\n\n const MOON = 1000000;\n\n const Plugin = function() {}\n\n Plugin.prototype.processPortfolioValueChange = function(event) {\n if(event.value > MOON) {\n alexa.say('Alexa, buy the best Champagne!');\n }\n };\n\n module.exports = Plugin;\n\nHave a look at the [events doc](./events.md) for all events your plugin can subscribe to. For technical inspiration it's easiest to look at the code of Gekko's plugins (here [`gekko/plugins.js`](https://github.com/askmike/gekko/blob/develop/plugins.js))." }, { "path": "docs/internals/server_api.md", "content": "# Server API\n\nThe Gekko project has three major components:\n\n - [Actual Gekko instance](./architecture.md)\n - A nodejs server that:\n - starts and manages gekkos\n - broadcasts all updates from all gekkos and tracks their overall state\n - has API calls to query and manage historical data (by importing more for example)\n - [A web UI (vue frontend project)](./gekko_ui.md)\n\nThe nodejs server can also be used standalone as a webserver in combination with your own software (such as a new UI, a mobile app or a higher level backtester), see [other software](../extending/other_software.md) for examples).\n\nThe server exposes two different APIs: A websocket API to push gekko updates and a REST API for everything else.\n\nWhen you run `node gekko --ui` it will automatically start a server. You can also do this manually by running:\n\n cd gekko/web\n node server\n\nThe server will now run on the host/port configured in `gekko/web/vue/public/UIConfig.js` (under api.host).\n\n## REST API\n\n### GET /api/info\n\nGet version information of current running Gekko Server.\n\nNOTE: The API does not have dedicated versioning, instead it uses the version of the complete Gekko project.\n\n**response**\n\n```\n{ \"version\": \"0.6.0\" }\n```\n\n### GET /api/strategies\n\nGet all strategies known to this Gekko.

You can use over 130 indicators to create your perfect prediction model (using [Talib's indicators](../strategies/talib_indicators.md) or [Tulip's indicators](../strategies/tulip_indicators.md)). *Why don't you combine Bollinger Bands, CCI and MACD with a STOCHRSI indicator?*\n\n## Automated Trading platform\n\nGekko can watch the realtime markets, automatically executing and evaluating your strategies in the process. Whilst doing this Gekko will store all market data it sees, this makes it possible to later simulate trading strategies against historical data to see whether they would have been profitable (backtesting).\n\n## Limitations\n\nGekko is not built for HFT or anything related to being the fastest (like arbitrage) as well as some other things. Please see the [scope page](./scope.md) to read more about what you can and cannot do with Gekko.\n\n## How does Gekko work?\n\n![Gekko architecture](https://wizb.it/gekko/static/architecture.jpg)\n\nRead more in the [architecture documentation](../internals/architecture.md).\n\n## Credits\n\n* The title is inspired by [Bateman](https://github.com/fearofcode/bateman).\n* This project is inspired by the [GoxTradingBot](https://github.com/virtimus/GoxTradingBot/) Chrome plugin (which in turn is inspired by [Goomboo's journal](https://bitcointalk.org/index.php?topic=60501.0)).\n\n## Final\n\nIf Gekko helped you in any way, you can always leave me a tip at (BTC) 13r1jyivitShUiv9FJvjLH7Nh1ZZptumwW\n\n## Disclaimer\n\nGekko (nor anyone behind this project) DOES NOT give investment advice.

Gekko aims to have a low barrier entry to writing your own strategies (however a basic scripting knowledge in javascript is required for users who create their own strategies). This page will discuss the scope of some components of Gekko, explaining how things are done and why they are done a certain way.\n\n## Market data\n\nGekko aggregates all market data into minutely candles (OHLC, VWP and amount of trades). This means Gekko only has to store candles on disk, which take up a predictable amount of space on your harddrive. The tradebot will use some additional market data (the orderbook) to execute orders efficiently, but this data is not visible anywhere else.\n\n## Strategies\n\nStrategies are simple scripts that handle new market data (OHLC candles) as well as calculated indicator results (strategies specify what indicators they want with which settings). Every time there is new data the strategy can determine to signal either LONG or SHORT. That's about it! This very simple design (candles + indicator values go in => signals come out) is quite powerful.\n\nUnfortunately this simple design can sometimes be limiting, here are some limitations:\n\n- Since strategies are only fed candles (and indicator values):\n - Strategies cannot act on a smaller timeframe than 1 minute.\n - Strategies cannot see any trades.\n - Strategies cannot look at the orderbook.\n- Strategies do not know what the current portfolio looks like.\n- Strategies can only trigger a LONG or SHORT which signals to go \"all in\".\n\n## Execution strategy\n\nWhen you are using Gekko for a real tradebot Gekko will create orders at the exchange whenever your strategy signals an advice (long or short). If your strategy signal a long advice Gekko will try to buy as much \"asset\" as it can get with all your \"currency\" (if your strat is running on USD/BTC that would mean buying BTC with all your USD). As for creating the orders Gekko is conservative and stays on your side of the orderbook (this means you don not lose on the spread, slippage or taker fees). An example:\n\nIf your strategy signals a LONG signal and this is the current orderbook:\n\n\"screen\n\nGekko will try to buy bitcoin by placing a limit order at a price of `4336.29` in the hope someone sells into the order. Every few seconds Gekko will readjust the order to stay on top of the orderbook. *Note that order simulation (in the paper trader and backtester) is handled differently, since the orderbook is not used in the simulation.*\n" }, { "path": "docs/introduction/supported_exchanges.md", "content": "## Supported exchanges\n\nGekko is able to directly communicate with the APIs of a number of exchanges. However communication with some exchanges is somewhat limited.

Gekko can store and run trading simulations over this data.\n- Live Trading: Gekko is able to automatically execute orders (based on the signals of your strategy).

Gekko Plus is hosting an official Strategy contest: submit your strategy and have a change to win 0.1 BTC! Read more details on [Gekko Plus](https://app.gekkoplus.com/contest).*\n\nStrategies are the core of Gekko's trading bot. They look at the market and decide what to do based on technical analysis indicators. A single strategy is limited to a single market on a single exchange.\n\nGekko currently comes with [a couple of strategies](./introduction.md) out of the box. Besides those you can also write your own strategy in javascript. If you want to understand how to create your own strategy you can watch this video or read the tech docs on this page.\n\n[![youtube video on how to create gekko strategies](https://gekko.wizb.it/_static/create-strat-vid.jpg)](https://www.youtube.com/watch?v=6-74ZhrG0BE)\n\nA strategy is a module with a few functions that get market data in the form of candles ([OHLC](https://en.wikipedia.org/wiki/Open-high-low-close_chart), volume, and the average weighted price) and output trading advice.\n\n## Strategy boilerplate\n\n // Let's create our own strategy\n var strat = {};\n\n // Prepare everything our strat needs\n strat.init = function() {\n // your code!\n }\n\n // What happens on every new candle?\n strat.update = function(candle) {\n // your code!\n }\n\n // For debugging purposes.\n strat.log = function() {\n // your code!\n }\n\n // Based on the newly calculated\n // information, check if we should\n // update or not.\n strat.check = function(candle) {\n // your code!\n }\n\n // Optional for executing code\n // after completion of a backtest.\n // This block will not execute in\n // live use as a live gekko is\n // never ending.\n strat.end = function() {\n // your code!\n }\n\n module.exports = strat;\n\n# Strategy lifecycle methods\n\nThe above boilerplate contains four functions. These functions are executed by Gekko like so:\n\n- When Gekko starts: run init.\n- On each new candle:\n - run [update](#update-function)\n - once the strategy has completed warmup:\n - run [log](#log-function)\n - run [check](#check-function)\n\n### init function\n\nExecuted when the trading strategy starts. Your strategy can initialize state and [register indicators](#Indicators).\n\n### update function\n\nThis function executes on every new candle. You can access the latest candle as the first (and only) parameter (it's also stored in `this.candle`).\n\n### log function\n\nThe log function is executed on every new candle when the `debug` flag is on (always off when running in the UI, as configured in [the config](../commandline/about_the_commandline.md) for CLI gekkos). Logging is used to log certain state from the strategy and can be used to debug your strategy to get more insights in why it took certain decisions.\n\n### check function\n\nMost strategies need to warmup before the trading strategy can be started. For example the strategy may be calculating a moving average for the first 3 candles, as such it must have at least 3 candles to output a number the strategy logic relies on. The check function is executed after the warmup period is over. The default required history is 0. You can set it like so in your init function:\n\n this.requiredHistory = 5; // require 5 candles before giving advice\n\nIf you find out in the check function that you want to give new advice to the trader you can use the advice function:\n\n this.advice({\n direction: 'long', // or short\n trigger: { // ignored when direction is not \"long\"\n type: 'trailingStop',\n trailPercentage: 5\n // or:\n // trailValue: 100\n }\n });\n\nThe trigger is optional, if the direction is long and the trigger is specified as a trailingStop this will request the trader to create a trail stop trigger.\n\n### candle variable\n\nThe following list of candle variables will be available when writing strategies, they are part of the candle object which is given to your `update` and `check` functions (it's also accessable through `this.candle`).\n\n - candle.close: the closing price of the candle\n - candle.high: the highest price of the candle\n - candle.low: the lowest price of the candle\n - candle.volume: the trading volume of that candle\n - candle.trades: number of trades in that candle\n\n## Things to keep in mind\n\n- You can activate your own strategy by setting `config.tradingAdvisor.strategy` to `custom` (or whatever you named your file inside the `gekko/strategies`) in the loaded config.\n- Gekko will execute the `update` function for every new candle. A candle is the size in minutes configured at `config.tradingAdvisor.candleSize` in the loaded config.\n- It is advised to set history `config.tradingAdvisor.historySize` the same as the requiredHistory as Gekko will use this property to create an initial batch of candles.\n- Never rely on anything based on system time because each method can run on live markets as well as during backtesting. You can look at the `candle.start` property which is a `moment` object of the time the candles started.\n\n## Strategy tools\n\nTo help you Gekko has a number of strategy tools.\n\n### Indicators\n\nGekko supports a few indicators natively, in addition to the integration of indicators from the library [TA-lib](http://ta-lib.org/).\n\n#### Example usage\n\nIf you want to use an indicator you can add it in the `init` function and Gekko will handle the updating for you on every candle (before the update and before the check call):\n\n // add a native indicator\n this.addIndicator('name', 'type', parameters);\n\nor\n\n // add a TA-lib indicator\n this.addTalibIndicator('name', 'type', parameters);\n\nor\n\n // add a Tulip indicator\n this.addTulipIndicator('name', 'type', parameters);\n\nThe first parameter is the name, the second is the indicator type you want and the third is an object with all indicator parameters. If you want an MACD indicator you can do it like so:\n\nIn your init function:\n\n // add a native indicator\n var parameters = {short: 10, long: 20, signal: 9};\n this.addIndicator('mynativemacd', 'MACD', parameters);\n\n // add a TA-lib indicator\n var parameters = {optInFastPeriod: 10, optInSlowPeriod: 21, optInSignalPeriod: 9};\n this.addTalibIndicator('mytalibmacd', 'macd', parameters);\n\n // add a Tulip indicator\n var parameters = {optInFastPeriod: 10, optInSlowPeriod: 21, optInSignalPeriod: 9};\n this.addTulipIndicator('mytulipmacd', 'macd', parameters);\n\nIn your check or update function:\n\n var result = this.indicators.mytalibmacd.result;\n\nSee the [TA-lib indicators](./talib_indicators.md) document for a list of all supported TA-lib indicators and their required parameters.\n\nSee the [Tulip indicators](./tulip_indicators.md) document for a list of all supported Tulip indicators and their required parameters.\n\n### Strategy parameters\n\nAdjust strategy execution by creating custom strategy parameters. This way the same strategy can execute strategies concurrently using different parameters for different markets. For example the MACD strategy has parameters concerning the underlying MACD indicator (such as values for the LONG and SHORT EMAs). Create custom configuration settings in the `config/strategies` directory:\n\n // custom settings:\n config.custom = {\n my_custom_setting: 10,\n };\n\nRetrieve them in your strategy like this:\n\n // anywhere in your code:\n log.debug(this.settings.my_custom_setting); // Logs 10\n\n___Note that the name of your configuration must be the same as the name of the strategy___\n\n### External libraries\n\nGekko uses a few general purpose libraries internally. The API from those libraries are available to you as well. Most notable libraries are [lodash](http://lodash.com/) (similar as underscore) and [async](https://github.com/caolan/async).\n\nYou can load them like so:\n\n // before any other code\n var _ = require('lodash');\n var async = require('async');\n\n### Logging\n\nGekko has a small logger you can use (preferably in your log function):\n\n // before any other code\n var log = require('../core/log.js');\n\n // in your log function\n log.debug('hello world');\n\n\n-----\n\nTake a look at the existing methods, if you have questions feel free to create an issue. If you created your own awesome strategies and want to share it with the world feel free to contribute it to gekko.\n" }, { "path": "docs/strategies/gekko_indicators.md", "content": "# Gekko indicators\n\nWhen [creating your own strategy](./creating_a_strategy.md) there are a few built in indicators you can use that ship with Gekko.\n\n## Example\n\nIf you want to use the MACD indicator from Gekko, you need to register it in your strategy like so:\n\n method.init = function() {\n var settings = {\n short: 10,\n long: 21,\n signal: 9\n };\n\n // add the indicator to the strategy\n this.addIndicator('mymacd', 'MACD', settings);\n }\n\n method.check = function() {\n // use indicator results\n var macdiff = this.indicators.mymacd.result;\n\n // do something with macdiff\n }\n\n## Indicators\n\nHere is a list of all supported indicators, click on them to read more about what they are and how to implement them in Gekko:\n\n- [EMA](#EMA)\n- [PPO](#PPO)\n- [CCI](#CCI)\n- [DEMA](#DEMA)\n- [LRC](#LRC)\n- [MACD](#MACD)\n- [RSI](#RSI)\n- [SMA](#SMA)\n- [TSI](#TSI)\n- [UO](#UO)\n\n### EMA\n\n> **What is an 'Exponential Moving Average - EMA'**\n> \"An exponential moving average (EMA) is a type of moving average that is similar to a simple moving average, except that more weight is given to the latest data.

Long indicates that Gekko the asset should be bought and short indicates that it should be sold.\n\nIf you are familiar with javascript you can easily create your own strategies. Here is a video explaining everything you need to know:\n\n[![youtube video on how to create gekko strategies](https://gekko.wizb.it/_static/create-strat-vid.jpg)](https://www.youtube.com/watch?v=6-74ZhrG0BE)\n\nBelow you can find simple and exemplary strategies that come with Gekko. These strategies come with Gekko and serve as examples.\n\nGekko currently comes with the following example strategies:\n\n - [DEMA](#DEMA)\n - [MACD](#MACD)\n - [PPO](#PPO)\n - [RSI](#RSI)\n - [StochRSI](#StochRSI)\n - [CCI](#CCI)\n - [talib-macd](#talib-macd)\n - [tulip-macd](#tulip-macd)\n\n### DEMA\n\nThis strategy uses `Exponential Moving Average crossovers` to determine the current trend the\nmarket is in. Using this information it will suggest to ride the trend. Note that this is\nnot MACD because it just checks whether the longEMA and shortEMA are [threshold]% removed\nfrom each other.\n\nThis strategy is fairly popular in bitcoin trading due to Bitcointalk user Goomboo. Read more about this strategy in [his topic](https://bitcointalk.org/index.php?topic=60501.0) or [here](http://stockcharts.com/school/doku.php?id=chart_school:technical_indicators:moving_averages).\n\nYou can configure the following parameters:\n\n # EMA weight (Ī±)\n # the higher the weight, the more smooth (and delayed) the line\n short = 10\n long = 21\n\n [thresholds]\n down = -0.025\n up = 0.025\n\n- short is the short EMA that moves closer to the real market (including noise)\n- long is the long EMA that lags behind the market more but is also more resistant to noise.\n- the down threshold and the up threshold tell Gekko how big the difference in the lines needs to be for it to be considered a trend. If you set these to 0 each line cross would trigger new advice.\n\n### MACD\n\nThe MACD is one of the most popular trend watching **indicators** in finance, it was created by Gerald Appel in the late 1970s. By using multiple price averages (EMAs) of different periods (one that follows the market more closely and one that lags behind, only catching bigger price swings). The indicator itself ouputs multiple numbers, when comparing them they can be interepted as signals that show when the trend of the price is changing.\n\nThe MACD **strategy** in Gekko is a simple strategy that implements the indicator. By comparing the difference between the EMAs from the signal the strategy triggers buy and sell signals. The strategy does come with additional logic:\n\n- **thresholds**: a signal will be triggered as soon as the difference goes above or below a configurable threshold, making the strategy more flexible than simply checking if the difference is above or below zero. If you set these to 0 each line cross would trigger new advice.\n- **persistance**: instead of trading as soon the difference is above or below the threshold, the strategy will wait a few candles to see if the difference keeps persisting. Only if it does the strategy will actually signal to Gekko to buy or sell. By setting persistance to 0 this behaviour is disabled.\n- **short** is the short EMA that moves closer to the real market (including noise)\n- **long** is the long EMA that lags behind the market more but is also more resistant to noise.\n- **signal** is the EMA weight calculated over the difference from short/long.\n\nRead more about it [here](http://stockcharts.com/school/doku.php?id=chart_school:technical_indicators:moving_average_convergence_divergence_macd).\n\nYou can configure the following parameters:\n\n # EMA weight (Ī±)\n # the higher the weight, the more smooth (and delayed) the line\n short = 10\n long = 21\n signal = 9\n\n # the difference between the EMAs (to act as triggers)\n [thresholds]\n down = -0.025\n up = 0.025\n # How many candle intervals should a trend persist\n # before we consider it real?\n persistence = 1\n\n### PPO\n\nVery similar to MACD but also a little different, read more [here](http://stockcharts.com/school/doku.php?id=chart_school:technical_indicators:price_oscillators_ppo).\n\nYou can configure the following parameters:\n\n # EMA weight (Ī±)\n # the higher the weight, the more smooth (and delayed) the line\n short = 12\n long = 26\n signal = 9\n\n # the difference between the EMAs (to act as triggers)\n [thresholds]\n down = -0.025\n up = 0.025\n # How many candle intervals should a trend persist\n # before we consider it real?\n persistence = 2\n\n- short is the short EMA that moves closer to the real market (including noise)\n- long is the long EMA that lags behind the market more but is also more resistant to noise.\n- signal is the EMA weight calculated over the difference from short/long.\n- the down threshold and the up threshold tell Gekko how big the difference in the lines needs to be for it to be considered a trend. If you set these to 0 each line cross would trigger new advice.\n- persistence tells Gekko how long the thresholds needs to be met until Gekko considers the trend to be valid.\n\n### RSI\n\nThe RSI indicator is and old but ever popular trend watching **indicator**, introduced in 1978 by J. Welles Wilder this simple indicator has never stopped to be a popular tool for traders. In its essence RSI follows a simple formula to measure the speed by which the price is changing. When the price keeps going up at an accelarating rate the market might be overbought and a reversal might come next.\n\nThe RSI **strategy** in Gekko is a simple strategy that implements the RSI indicator. By calculating the RSI as the market develops this strategy can trigger buy or sell signals based on the RSI going too high (overbought) or too low (oversold). The strategy does come with additional logic:\n\n- **interval** is the amount of periods the RSI should use.\n- **thresholds** determine what level of RSI would trigger an up or downtrend.\n- **persistance**: instead of trading as soon the difference is above or below the threshold, the strategy will wait a few candles to see if the difference keeps persisting. Only if it does the strategy will actually signal to Gekko to buy or sell. By setting persistance to 0 this behaviour is disabled.\n\nRead more about it [here](http://stockcharts.com/school/doku.php?id=chart_school:technical_indicators:relative_strength_index_rsi).\n\nYou can configure the following parameters:\n\n interval = 14\n\n [thresholds]\n low = 30\n high = 70\n # How many candle intervals should a trend persist\n # before we consider it real?\n persistence = 2\n\n### StochRSI\n\nThe StochRSI indicator uses an RSI indicator at its core and as such is similar to the RSI strategy that uses this indicator. The difference is that after the RSI is calculated a stochastic oscillator is calculated over the resulting RSI values. When a market is trending upwards for a long time the RSI values tend to go and stay high. The stochastic oscillator will compare the RSI values from the last period with eachother. This results in the StochRSI indicator therefor indicate how high or low the RSI values have been historically over the last n periods.\n\nThe StochRSI **strategy** in Gekko is a simple strategy that implements the StochRSI indicator. By calculating the StochRSI as the market develops this strategy can trigger buy or sell signals based on the signal going too high (overbought) or too low (oversold). The strategy does come with configurables:\n\n- **interval**: This setting defines both the RSI interval used to calculate the RSI values as well as the historical period used by the stochastic oscillator to compare RSI values with.\n- **persistance**: instead of trading as soon the difference is above or below the threshold, the strategy will wait a few candles to see if the difference keeps persisting. Only if it does the strategy will actually signal to Gekko to buy or sell. By setting persistance to 0 this behaviour is disabled.\n- **thresholds**: The high and low thresholds are defined as numbers between 1 and 100. Different from StochRSI in other trading systems, this number indicates a percentage instead of a fraction of 1.\n\nYou can configure the following parameters:\n\n interval = 3\n\n [thresholds]\n low = 20\n high = 80\n persistence = 3\n\n### CCI\n\nYou can configure the following parameters:\n\n # constant multiplier. 0.015 gets to around 70% fit\n constant = 0.015\n\n # history size, make same or smaller than history\n history = 90\n\n [thresholds]\n up = 100\n down = -100\n persistence = 0\n\n[TODO!]\n\n### talib-macd\n\nSimilar to the default MACD strategy, this showcases how to add a TA-lib indicator to a strategy.\n\nYou can configure the following parameters:\n\n [parameters]\n optInFastPeriod = 10\n optInSlowPeriod = 21\n optInSignalPeriod = 9\n\n [thresholds]\n down = -0.025\n up = 0.025\n\n### tulip-macd\n\nSimilar to the default MACD strategy, this showcases how to add a Tulip indicator to a strategy.\n\nYou can configure the following parameters:\n\n [parameters]\n optInFastPeriod = 10\n optInSlowPeriod = 21\n optInSignalPeriod = 9\n\n [thresholds]\n down = -0.025\n up = 0.025\n\n[TODO!]\n" }, { "path": "docs/strategies/talib_indicators.md", "content": "# TA-lib indicators\n\nWhen writing [your own strategy](./creating_a_strategy.md) you can use all indicators offered by [the TA-lib library](http://ta-lib.org/function.html).

The KO is derived from three types of data: the high-low price range, volume, and accumulation/distribution. Price range is a measure of movement and the force behind that movement is volume. Accumulation is when the sum of today's [high]+[low]+[close] is greater than yesterday's. Distribution is when today's sum is less than the yesterday's. When the sums are equal, the existing trend is maintained.\n\nRequired parameters:\n\n - optInFastPeriod\n - optInSlowPeriod\n\n### linreg\n\nThe Linear Regression is a smoothing functions that works by preforming linear least squares regression over a moving window. It then uses the linear model to predict the value for the current bar.\n\nRequired parameters:\n\n - optInTimePeriod\n\n### linregintercept\n\nMore information about the [Linear Regression Intercept](https://en.wikipedia.org/wiki/Simple_linear_regression)\n\nRequired parameters:\n\n - optInTimePeriod\n\n### linregslope\n\nMore information about the [Linear Regression Intercept](https://en.wikipedia.org/wiki/Simple_linear_regression)\n\nRequired parameters:\n\n - optInTimePeriod\n\n### macd\n\nMore information about the [MACD](https://www.tradingview.com/wiki/MACD_(Moving_Average_Convergence/Divergence))\n\nRequired parameters:\n\n - optInFastPeriod\n - optInSlowPeriod\n - optInSignalPeriod\n\n### marketfi\n\nThe Market Facilitation Index indicator combines price and volume in the analysis to establish the effectiveness of price movement by computing the price movement per volume unit. To calculate the Market Facilitation Index indicator the difference between the low and the high price are taken and divided by the volume.\n\nThis indicator does not require any parameters.\n\n### mass\n\nThe Mass Index indicator is used for finding trend reversals, based on the premise that reversals are likely to happen when the price range widens. It does not have a directional bias. The calculation, which compares the previous trading ranges (highs minus lows), uses Exponential Moving Averages (EMA). If there is substantial movement, the Mass Index Indicator increases if there is insubstantial movement the Mass Index Indicator decreases. \n\nFormula (usually a 9 period EMA is used)\n\n Single EMA = (x)-period exponential moving average (EMA) of the high-low differential \n Double EMA = (y)-period EMA of the (x)-period EMA of the high-low differential \n EMA Ratio = Single EMA divided by Double EMA \n Mass Index = 25-period sum of the EMA Ratio \n\nRequired parameters:\n\n - optInTimePeriod\n\n### medprice\n\nThe median price indicator calculates the mean of the high and low for a bar. Despite the name, it does not calculate an actual median value.\n\n medprice(t) = (high(t) + low(t)) / 2\n\nThis indicator does not require any parameters.\n\n### mfi\n\nMore information about the [MFI](https://www.tradingview.com/wiki/Money_Flow_(MFI))\n\nRequired parameters:\n\n - optInTimePeriod\n\n### msw\n\nThe Maximum Entropy Spectrum Analysis indicator is a unique way to accurately measure short-term cycles in a market. It utilizes two sine plots to illustrate if the market is in a cycle mode or in a trend mode. When the two plots resemble a sine wave the market is in cycling mode. When the plots start to wander the market is in a trend mode. \nThe MESA Sine Wave indicator is a leading indicator that will anticipate cycle mode turning points rather than waiting for confirmation as is seen with most other oscillators. The indicator has the additional advantage that trend mode whipsaw signals are minimized.\n\nRequired parameters:\n\n - optIn\n\n### natr\n\nThe Normalized Average True Range is a measure of volatility.\nIt is calculated as follows:\n\n natr = (atr(t) / close(t)) * 100\n\nRequired parameters:\n\n - optInTimePeriod\n\n### nvi\n\nMore information about the [NVI](https://en.wikipedia.org/wiki/Negative_volume_index)\n\nThis indicator does not require any parameters.\n\n### obv\n\nMore information about the [OBV](https://www.tradingview.com/wiki/On_Balance_Volume_(OBV))\n\nThis indicator does not require any parameters.\n\n### ppo\n\nMore information about the [PPO](https://www.tradingview.com/wiki/Price_Oscillator_(PPO))\n\nRequired parameters:\n\n - optInFastPeriod\n - optInSlowPeriod\n\n### psar\n\nMore information about the [Parabolic SAR](https://www.tradingview.com/wiki/Parabolic_SAR_(SAR))\n\nRequired parameters:\n\n - optInAcceleration\n - optInMaximum\n\n### pvi\n\nMore information about the [PVI](https://en.wikipedia.org/wiki/Negative_volume_index)\n\nThis indicator does not require any parameters.\n\n### qstick\n\nThe Qstick Indicator identifies trends on a chart. It is calculated by taking an 'n' period moving average of the difference between the open and closing prices. A Qstick value greater than zero means that the majority of the last 'n' days have been up, indicating that buying pressure has been increasing. In summary, the measure provides an approximation for a securityā€™s EMA, opening price, closing price, and their difference, as well as these values SMA.\n\nRequired parameters:\n\n - optInTimePeriod\n\n### roc\n\nMore information about the [Rate of Change](https://www.tradingview.com/wiki/Rate_of_Change_(ROC))\n\nRequired parameters:\n\n - optInTimePeriod\n\n### rocr\n\nRate Of Change Ratio calculates the change between the current price and the price n bars ago.\n\nRequired parameters:\n\n - optInTimePeriod\n\n### rsi\n\nMore information about the [RSI](https://www.tradingview.com/wiki/Relative_Strength_Index_(RSI))\n\nRequired parameters:\n\n - optInTimePeriod\n\n### sma\n\nMore information about the [SMA](https://www.tradingview.com/wiki/Moving_Average)\n\nRequired parameters:\n\n - optInTimePeriod\n\n### stoch\n\nMore information about the [STOCH](https://www.tradingview.com/wiki/Stochastic_(STOCH))\n\nRequired parameters:\n\n - optInFastKPeriod\n - optInSlowKPeriod\n - optInSlowDPeriod\n\n### sum\n\nThe Sum Over Period indicator simply returns the sum of the last n bars.\n\nRequired parameters:\n\n - optInTimePeriod\n\n### tema\n\nThe Triple Exponential Moving Average is similar to the Exponential Moving Average or the Double Exponential Moving Average, but provides even less lag. Triple Exponential Moving Average is probably best viewed as an extension of Double Exponential Moving Average.\n\nIt can be expressed in terms of the Exponential Moving Average as follows:\n\n tema = 3 * ema(in) - 3 * ema(ema(in)) + ema(ema(ema(in)))\n\nRequired parameters:\n\n - optInTimePeriod\n\n### tr\n\nTrue range is a measure of volatility. It represents how much a security changed price on a given day.\n\nTrue range for each day is the greatest of:\n\n - Day's high minus day's low\n - The absolute value of the day's high minus the previous day's close\n - The absolute value of the day's low minus the previous day's close\n\nThis indicator does not require any parameters.\n\n### trima\n\nThe Triangular Moving Average is similar to the Simple Moving Average but instead places more weight on middle portion of the smoothing period and less weight on the newest and oldest bars in the period.\nIt is calculated for each bar as the weighted arithmetic mean of the previous n bars. For example, the weights w for an n of 4 are: 1, 2, 2, 1. The weights w for a n of 7 are: 1, 2, 3, 4, 3, 2, 1. It's easy to see why it's called the Triangular Moving Average.\n\nRequired parameters:\n\n - optInTimePeriod\n\n### trix\n\nMore information about the [TRIX](https://www.tradingview.com/wiki/TRIX)\n\nRequired parameters:\n\n - optInTimePeriod\n\n### tsf\n\nThe Time Series Forecast indicator displays the statistical trend of a security's price over a specified time period. The trend is based on linear regression analysis. Rather than plotting a straight linear regression trendline, the Time Series Forecast plots the last point of multiple linear regression trendlines. The resulting TSF indicator is sometimes referred to as the \"moving linear regression\" indicator or the \"regression oscillator.\"\n\nRequired parameters:\n\n - optInTimePeriod\n\n### typprice\n\nThe Typical Price calculates the arithmetic mean of the high, low, and close of a bar.\n\nThis indicator does not require any parameters.\n\n### ultosc\n\nMore information about the [UO](https://www.tradingview.com/wiki/Ultimate_Oscillator_(UO))\n\nRequired parameters:\n\n - optInTimePeriod1\n - optInTimePeriod2\n - optInTimePeriod3\n\n### vhf\n\nThe Vertical Horizontal Filter determines whether prices are in a trending phase or a congestion phase. It is used to dertermine which other indicators are to be used in the current market trend. For example if the VHF suggests the market is in a range then a [mesa] could be used if the VHF suggests the market is in a range then one could use a [psar] to determine entry and exit points.\n\nRequired parameters:\n\n - optInTimePeriod\n\n### vidya\n\nThe Variable Index Dynamic Average indicator modifies the Exponential Moving Average by varying the smoothness based on recent volatility.\n\nRequired parameters:\n\n - optInFastPeriod\n - optInSlowPeriod\n - optInAlpha\n\n### volatility\n\nThe Annualized Historical Volatility indicator calculates the volatility over a moving window.\n\nRequired parameters:\n\n - optInTimePeriod\n\n### vosc\n\nThe Volume Oscillator identifies trends in volume using two moving averages of volume, one fast and one slow. The fast volume moving average is then subtracted from the slow moving average. \n\nRequired parameters:\n\n - optInFastPeriod\n - optInSlowPeriod\n\n### vwma\n\nThe Volume Weighted Moving Average is simalair to a Simple Moving Average, but it weights each bar by its volume.\n\nRequired parameters:\n\n - optInTimePeriod\n\n### wad\n\nWilliams AD is a running sum of positive accumulation values (buying pressure) and negative distribution values (selling pressure), as determined by price's location within a given day's true range. The day's accumulation/distribution is then calculated by comparing today's closing price to yesterday's closing price.\nTo calculate the Williams' Accumulation/Distribution indicator, determine:\n\n True Range High (TRH) = Yesterday's close or today's high whichever is greater\n True Range Low (TRL) = Yesterday's close or today's low whichever is less\n \nThe Williams' Accumulation/Distribution indicator is a cumulative total of the daily values:\n\n - Williams A/D = Today's A/D + Yesterday's Williams A/D\n\nThis indicator does not require any parameters.\n\n### wcprice\n\nThe weighted close price indicator calculates the mean of the high, low, and close of a bar, but the close price is weighted to count for double.\n\nThis indicator does not require any parameters.\n\n### wilders\n\nThe Welles Wilder Smoothing indicator is basically the same as an [EMA](#ema) and can be used in the same manner. \nIt uses a different calculation but can be easily calculated by simply converting EMA values as follows:\n\n wilders = (ema + 1) / 2\n\nRequired parameters:\n\n - optInTimePeriod\n\n### willr\n\nMore information about the [Williams R](https://www.tradingview.com/wiki/Williams_%25R_(%25R))\n\nRequired parameters:\n\n - optInTimePeriod\n\n### wma\n\nMore information about the [WMA](https://en.wikipedia.org/wiki/Moving_average#Simple_moving_average)\n\nRequired parameters:\n\n - optInTimePeriod\n\n### zlema\n\nZero-Lag Exponential Moving Average modifies a Exponential Moving Average to greatly reduce lag.\n\nRequired parameters:\n\n - optInTimePeriod\n" }, { "path": "exchange/.npmignore", "content": "nusadua" }, { "path": "exchange/README.md", "content": "# Gekko Broker\n\nsee [the docs](https://gekko.wizb.it/docs/gekko-broker/introduction.html)." }, { "path": "exchange/dependencyCheck.js", "content": "const deps = require('./package.json').dependencies;\n\nconst missing = [];\n\nObject.keys(deps).forEach(dep => {\n try {\n require(dep);\n } catch(e) {\n if(e.code === 'MODULE_NOT_FOUND') {\n missing.push(dep);\n }\n }\n});\n\nif(missing.length) {\n console.error(\n '\\nThe following Gekko Broker dependencies are not installed: [',\n missing.join(', '),\n '].\\n\\nYou need to install them first, read here how:',\n 'https://gekko.wizb.it/docs/installation/installing_gekko.html#Installing-Gekko-39-s-dependencies\\n'\n );\n process.exit(1);\n}\n" }, { "path": "exchange/exchangeChecker.js", "content": "const _ = require('lodash');\nconst fs = require('fs');\nconst moment = require('moment');\nconst errors = require('./exchangeErrors');\n\nconst Checker = function() {\n _.bindAll(this);\n}\n\nChecker.prototype.getExchangeCapabilities = function(slug) {\n if(!fs.existsSync(__dirname + '/wrappers/' + slug + '.js'))\n throw new errors.ExchangeError(`Gekko does not know the exchange \"${slug}\"`);\n\n return require('./wrappers/' + slug).getCapabilities();\n}\n\n// check if the exchange is configured correctly for monitoring\nChecker.prototype.cantMonitor = function(conf) {\n var slug = conf.exchange.toLowerCase();\n var exchange = this.getExchangeCapabilities(slug);\n\n if(!exchange)\n return 'Gekko does not support the exchange ' + slug;\n\n var name = exchange.name;\n\n if('monitorError' in exchange)\n return 'At this moment Gekko can\\'t monitor ' + name + ', find out more info here:\\n\\n' + exchange.monitorError;\n\n var name = exchange.name;\n\n if(!_.includes(exchange.currencies, conf.currency))\n return 'Gekko only supports the currencies [ ' + exchange.currencies.join(', ') + ' ] at ' + name + ' (not ' + conf.currency + ')';\n\n if(!_.includes(exchange.assets, conf.asset))\n return 'Gekko only supports the assets [ ' + exchange.assets.join(', ') + ' ] at ' + name + ' (not ' + conf.asset + ')';\n\n var pair = _.find(exchange.markets, function(p) {\n return p.pair[0] === conf.currency && p.pair[1] === conf.asset;\n });\n\n if(!pair)\n return 'Gekko does not support this currency/assets pair at ' + name;\n\n // everything is okay\n return false;\n}\n\n// check if the exchange is configured correctly for fetching\n// full history\nChecker.prototype.cantFetchFullHistory = function(conf) {\n var slug = conf.exchange.toLowerCase();\n var exchange = this.getExchangeCapabilities(slug);\n\n if(this.cantMonitor(conf))\n return this.cantMonitor(conf);\n\n var name = exchange.name;\n\n if(!exchange.providesFullHistory)\n return 'The exchange ' + name + ' does not provide full history (or Gekko doesn\\'t support importing it)';\n\n if (\"exchangeMaxHistoryAge\" in exchange) {\n if (moment(config.importer.daterange.from) < moment().subtract(exchange.exchangeMaxHistoryAge, \"days\")) {\n return 'Unsupported date from!
