I have a background in stock, option trading algorithm, platform development using Python.
I mainly use APEX, Interactive Broker as brokerage platform as well as other platforms too.
Polygon, Tiingo, Alpha Vantage, IB are great providers for stock and trading related information.
My preferred programming language to develop trading algorithm is Python.
I have developed from simple stock trading algorithm to complex option combo trading algorithm like Butterfly, Iron Condor etc.
Feel free to ping me if you want to develop any kind of trading algorithms and platforms.
Best regards,
