Congrats!! If I were you I would always set monetary goals. Setting goals like being net positive everyday are good but if you're going to trade for a living you should be net positive most days anyways or you shouldn't be trading. Cheers.
When you say you put out a market order through ARCA does that mean you put a bid at market or offer at market or you just throw out a general market order and see where you get filled? Thanks.
