institutional or retail? i wanted to do this on a retail scale but i don't know where to start as far as APIs for orders and market feeds. do you have any pointers?

Retail.

I do low-freq stat arb and it's modestly profitable. I just use IBKR's API, their snapshot data, and postgres. Nothing fancy.

Feel free to shoot me an email, it's in my profile.
