Would it be realistic to net $100/day looking for and exploiting small time risk-free arbitrage situations with mispriced securities using IB? I would give it a try in a Margin IRA. I have a programming background, and I just learned about put-call parity and other types of arbitrage. 1. Would I be able to find these situations and exploit them as an at home algo trader or would all the big HFT shops beat me to the gun every single time? 2. Would IB even execute a combo order that gave me a risk-free profit? I'm sure I misused some terms and came off as ignorant in general there, but no need to take it easy on me. I don't want to waste my time if this isn't realistic at all.
