Yeah, I initially tried that actually. They have very low resolution data and do not provide raw trades/quotes (something like a message every 250ms), you cannot watch the entire market so you're stuck with like 100 tickers [1] vs 5500 tickers, and fetching historical data is very cumbersome. You can basically pull down pre-aggregated candlestick data and I wanted to base things off the raw trades/quotes. I actually probably spend a month or two trying to make this work. So, that's why I'm using polygon.io in that you can stream trades/quotes for the entire stock market in real-time, without any caps, which is amazing!
