Introducing the Fire by Arthur Trading Engine
This trading engine is an open source Google Sheets add-on that is designed for option traders to have real time portfolio alerts and analysis.
The project is found on GitHub: https://github.com/jarthursquiers/FireByArthurTradingEngine
I also created a publicly available Google Sheet, with the trading engine embedded, that can be copied to your own personal Google drive and used. You can visit my blog post that describes how to access this.
The code is written in the TypeScript language, using object oriented patterns to keep it extensible.
As brokerage APIs become available, this project could also be extended into an auto-trading engine.
All the Best,
-J. Arthur Squiers
