FIXations!

A set of tools to handle FIX protocol data

• fix_tags - explore FIX tags and their associated values either as CLI output or a GUI-like textual interface
• fix_parse_log - extract FIX lines from a (log) file and present them in a nicely formatted grid
• webfix - present copy-n-paste'd FIX lines into a nicely formatted grid

Installation

pip3 install fixations

webfix

Webfix needs to be used with either Flask (for dev purposes)

$ python -m flask --app fixations.webfix run
 * Serving Flask app 'fixations.webfix'
 * Debug mode: off
WARNING: This is a development server. Do not use it in a production deployment. 
Use a production WSGI server instead.
 * Running on http://127.0.0.1:5000
Press CTRL+C to quit

or something like gunicorn (or other WSGI servers) for production uses:

$ gunicorn fixations.wsgi:app

FIX reference data source

The data is extracted from the FIX specs available here:

https://www.fixtrading.org/packages/fix-repository-2010/ (see fix_repository_2010_edition_20200402.zip).

NOTE: it requires the creation of a login/password to access it.

TODO:

1. create a hyperlink to FIX specs for each tag based on FIX version :white_check_mark:
2. add more info to README.md. Use rule80A and 47 as example for fix_args :white_check_mark:
3. add more example(s)
4. add some pytest to detect the FIX version for example :white_check_mark:
5. add "direction" to columns to show whether it's a request or a response
6. catch exceptions and display them on the webpage
7. deploy to https://vercel.com/
8. allow creating an ASCII table equivalent suitable to be cut-n-paste into a document for example
9. add a short link ala tinyurl and save it into a sqlite3 db store :white_check_mark:
10. black theme?
11. allow to have no leading timestamp and use the timestamp FIX tags instead :white_check_mark:
12. add proper Logger
13. add DB stats
14. pypi.org can't display the ASCII screencast images. Need to reference GitHub's full path?
15. Give the option to remove or hide/obfuscate some sensitive fields such as tag55 or senderCompId/targetComPid :white_check_mark:
16. Show the delta between each timestamp (below each timestamp) :white_check_mark:
17. Transpose the grid/matrix :white_check_mark:
18. Shift-Enter = pressing on [Parse FIX] button :white_check_mark:
19. Support FIX Repeating Groups :white_check_mark:
20. When using fix_parse_log.py, also upload the same data to the webfix app to generate a tiny URL :white_check_mark:
21. Add an option to sort the entries by log timestamp. Useful when grep over multiple files
22. Add smart comments when comments aren't provided, based on simple rules on tags: 35=D and 8002=1 then comment="blah"
23. Add top tags to the ASCII version
