Apart from interpreting the binary data according to the specification of the protocol we also have to retrieve information of past orders that new messages are referring to.\\\nWe can see this in the following example of submission and deletion of an order, according to the specifications the Add and Delete order would be:\n\n| Message Type | Locate | Tracking | ns since 00:00 | Order id | Buy/Sell | Size | Stock | Price | MPID |\n|--------------|--------|----------|----------------|----------|----------|------|-------|---------|------|\n| A | 8007 | 0 | 28802131792425 | 45785 | B | 3000 | USO | 14.7200 | id_1 |\n| ... | | | | | | | | | |\n| D | 8007 | 0 | 28802131843697 | 45785 | | | | | id_1 |\n\nAs we can see once we observe the deletion order no information about the direction, size, stock and price are reported. Hence at each time we have to keep track of all the active orders in the book, in order to know what to do once we encounter the deletion order.\n\nThe output of the program are two .csv file with the following structure:\n\n##### messages of 08/30/2018 PSX AAPL\n\n| time | type | id | side | size | price | cancSize | execSize | oldId | oldSize | oldPrice | MPID |\n|----------------|------|-------|------|------|--------|----------|----------|-------|---------|----------|------|\n| 29041353544851 | A | 49816 | 1 | 100 | 223.39 | | | | | | id_1 |\n| 29041495720727 | D | 49816 | 1 | 0 | 223.39 | 100 | | | | | id_1 |\n| ... | ... | | | | | | | | | | |\n\n##### book of 08/30/2018 PSX AAPL\n\n| time | 1_bid_price | 1_bid_vol | 1_ask_price | 1_ask_vol | ... | n_ask_vol |\n|----------------|-------------|-----------|-------------|-----------|-----|-----------|\n| 29041353544851 | | | 223.39 | 100 | ... | ... |\n| 29041495720727 | | | | | | |\n| ... | | | | | | |\n\n## Installation\n\nOS X & Linux:\n\n\n```sh\ngit clone https://github.com/martinobdl/ITCH\ncd ITCH\nmake\n```\n\nIn order to get some data needed to run the program **(800MB)**\n```sh\nwget ftp://anonymous:@emi.nasdaq.com/ITCH/Nasdaq\\ PSX\\ ITCH/20190327.PSX_ITCH_50.gz -P ./data/binary\n\n# this file exists at date 05/02/2019\n# otherwise download manually from the ftp and put the\n# .gz file in ITCH/data/binary\n```\n\n## Usage example\n\nTo reconstruct the book we can use the bash wrapper BookConstructor.sh which has the following usage:\n\n```\nusage: ./BookConstructor.sh [-lfh] [-n #] data_folder mm/dd/yyyy venue ticker\n ./BookConstructor.sh [-l] data_folder\n ./BookConstructor.sh [-h]\n\n -h, --help Display usage instructions\n -l, --list Display all the date venues available at data_folder/binary\n -f, --force To force program execution if output files already exists\n -n, Number of levels to store for the book, default is 5\n```\n\nfor example `./BookConstructor.sh data_folder mm/dd/yyyy venue ticker -n N`\nwill produce two output files named:\n\n```\ndata_folder/book/mmddyyyy.venue_ITCH50_ticker_book_N.csv\ndata_folder/messages/mmddyyyy.venue_ITCH50_ticker_message.csv\n```\n\n###### example\n\nGiven that you have in `/../../ITCH/data/binary` the file `PSX_ITCH/20190327.PSX_ITCH_50.gz`\n\n``` sh\ncd /../../ITCH\n./BookConstructor.sh ./data 03/27/2019 PSX SPY\n```\n\nthis will create two output .csv files, namely:\n``` sh\n/../../ITCH/data/book/03272019.PSX_ITCH50_AAPL_book_5.csv\n/../../ITCH/data/messages/03272019.PSX_ITCH50_AAPL_message.csv\n```\n\n# Detailed output description\n\nHere we report detailed description of message file output of the program:\n\nAt discrete time T1,T2,T3,... an output will be released by NASDAQ, the field names may have different meaning depending on the type of message. Hence here we will give a detailed description of the message csv.\n\n| time | type | id | side | size | price | cancSize | execSize | oldId | oldSize | oldPrice | MPID |\n|------|------|--------|------------------------|-------------------------------------------------------------|--------------------------------------------|-------------------------------|-----------------------------|--------------|-----------------------------------|-----------------------------------|------|\n| ... | A | ... | ... | added size | limit price of the add order | - | - | - | - | - | mpid of the market partecipant who issued the order |\n| ... | D | ... | ... | remaining size after the deletion (may be total or partial) | price of the original order | canceled size by the message | - | - | - | - | mpid of the market partecipant who deleted the order |\n| ... | E | ... | ... | remaining size after the execution | price of the order being executed | - | size being executed | - | - | - | mpid of the mp whos resting order is being executed |\n| ... | P | ... | ... | execution of an hidden order | price of the execution | - | size of the hidden execution | - | - | - | - |\n| ... | R | new id | equal to the old order | new size | new limit size | - | - | old order id | size of the order being replaced | price of the order being replaced | same as the old order (if any) |\n| ... | C | ... | ... | remaining size after the execution | price at which the order is being executed | - | - | - | - | original price of the order | the mpid of the executed order |\n\n\n## Development setup\n\nIn the gtest folders there are unit tests in order to test the principal components of the software, they are the Google c++ unittesting libraries. To compile and run the tests you would need the gtests and gmock libraries.\nThey can be installed in the following way. Refer to for more details about the installation.\n\nTo install gtest-gmock:\n\n```sh\n# gtests\nsudo apt-get install libgtest-dev\nsudo apt-get install cmake\ncd /usr/src/gtest\nsudo cmake CMakeLists.txt\nsudo make\nsudo cp *.a /usr/lib\n\n#gmock\nsudo apt-get install libgmock-dev\ncd /usr/src/gmock\nsudo mkdir build\nsudo cmake ..\nsudo make\nsudo cp *.a /usr/lib\n```\n\nTo run the tests:\n```sh\ncd /../../ITCH\nmake test\n./bin/executeTests\n```\n\n## Application Example\n\nIn the python folder there are some examples on how the program might be used to perform research on HFT.\\\n`environment.py` is the environment definition and `Algo.py` is the agent abstract class from which we would implement the strategy.\\\nThe environment definition provides also some visualization tools.\n\nrequirements:\n```\npython3\nnumpy\npandas\nmatplotlib\ntkinter\ntqdm\n```\n\n###### To run the environment visualization tool:\n\n```sh\npython3 /../../ITCH/python/environment.py mmddyyyy venue stock\n```\n\n###### To run a simple low regret fixed spread strategy:\n```sh\npython3 /../../ITCH/python/Algo_fixedSpread.py\n```\n\nThe implemented strategy can be found at\n\n[# 2013] Abernethy, J., Kale, S., Adaptive Market Making via Online Learning.\n\n## Screen shots\n\n### Implementation Class Diagram\n> For more details about the API see the documentation in the doc/ folder\n![](images/classDiagram.png)\n\n### Order Book visualization Tool (from environment.py)\n![](images/Figure_2.png)\n![](images/ezgif-1-77b8a25c6b7c.gif)\n\n\n--- \n### Citations\nIf you use this software in your research, please cite the paper using the following BibTeX:\n\n```\n@misc{https://doi.org/10.5281/zenodo.5209267,\n doi = {10.5281/ZENODO.5209267},\n url = {https://zenodo.org/record/5209267},\n author = {Bernasconi-De-Luca, Martino and Fusco, Luigi and Dragić, Ozrenka},\n title = {martinobdl/ITCH: ITCH50Converter},\n publisher = {Zenodo},\n year = {2021},\n copyright = {Open Access}\n}\n```\n\n\n\n## Contributors\n\n* Luigi Fusco \n* Ozrenka Dragić \n* Martino Bernasconi-de-Luca \n\n" }, { "path": "doc/Doxyfile", "content": "# Doxyfile 1.8.15\n\n# This file describes the settings to be used by the documentation system\n# doxygen (www.doxygen.org) for a project.\n#\n# All text after a double hash (##) is considered a comment and is placed in\n# front of the TAG it is preceding.\n#\n# All text after a single hash (#) is considered a comment and will be ignored.\n# The format is:\n# TAG = value [value, ...]\n# For lists, items can also be appended using:\n# TAG += value [value, ...]\n# Values that contain spaces should be placed between quotes (\\\" \\\").\n\n#---------------------------------------------------------------------------\n# Project related configuration options\n#---------------------------------------------------------------------------\n\n# This tag specifies the encoding used for all characters in the configuration\n# file that follow.
