CBOE PITCH Viewer
+
+A tool for viewing/debugging PITCH messages
+
+
DEMO: cboe.haydenbickerton.com
+
Here is a screenshot of the web interface:
+
+
Run the compiled viewer
+
$ cd /client/dist
+$ python3 -m http.server 8080
+...
+
+
Then open your browser to http://localhost:8080/ to see the viewer.
+

Notes
+
The code is in one of two steps:
+
+- Converting the PITCH Message Specifications into usage python/javascript parsers/models
+
+/structs/specs - YAML’s extracted from PDF using tabula/notebooks/Building Structs.ipynb - Notebook to build YAMLs into py/js models
+
+- Web interface/app/viewer to view uploaded message data
+
+/client/ - Vue.js app (pictured above)/structs/compiled/Cboe.js - Generated in step 1 , imported by web app
+
+
+
Initially I went the route of making the python models and types for a backend parsing service, as I’m primarily a python developer. But copy-pasting each value into hardcoded classes when there’s clearly an existing spec somewhere isn’t what I’d normally do. So I did the YAMLs, and referenced those as the specs in the vue app. More about this in Building Structs.ipynb. I left code from initial run in /cboe-sdk/ and /notebooks/Modeling.ipynb.

Other
+
This feels very similar to ACORD AL3, which is a popular fixed length messaging standard used by insurance software for the transmission of policies and claims. I created the AL3 implementation during my time at BriteCore .
+
The idea for the viewer comes from working with AL3, as there are thousands of different data/message types and no straightforward tool for displaying a feed of messages and their fields.
