hajimow, do you cancel or not?
Good question. My cancellation fee for YTD is about $2. My YTD commission is about $6000. Here are some tricks to avoid cancellation fee.
1- Combo orders don't have cancellation fee but you don't get good commission on combo fee (you get standard fee). so you can modify combo orders as many times as you want.
2- When I put an order and then the price moves away from me and I want to change my order, I just put a new order without cancelling the first one. After the second one gets executed, and if I fear that the first one might get executed too, I cancel the first one. Otherwise I let it expire. Sometimes IB cancels my first order because I don't have margin for both orders. When IB cancels your order, you don't pay cancellation fee.
