Where is the market data (price, volume, etc) from? All open source projects related to stocks seem to use Yahoo quotes, which is essentially abandoned and not supported at all. No SLA or any indication of long term survival.
I found Alpaca[1] which looks decent in terms of a stock API and their upstream data provider Polygon.io[2] which looks even better but costs $199/mo for essentially per tick market data.
