Stock Price Data Streaming


Right now I’m working on getting data on the price action of a stock. Right now, I have an algo with a profit parameter of +.01 cents to test out, but want to see if we can do fractional cent trades. Would I be able to do an algo with +.001 profit? If I can do these fractional cent trades, where do I get the data from?

I’m currently seeing that Alpaca price data gives price action to 2 decimal places. So let me know if any of you guys know a free way I can get price data to 3 decimal places (or 4). I see on the Alpaca website that it gives you profit/loss to 4 decimal places, and I know that fractional cent trades are possible because stocks and cryptos like Dogecoin show prices to 4+ decimal places.
