Does anybody know if you have to pay the modify fee twice if you ammend for example a straddle with IB; in other words is a straddle actually two single orders or is it just 1 order and if cancelled/modified you have to pay only 1 time the cancel/modify fee? Thanks in advance
I don't think there's cancel fees on combination orders. If you want to find out, place one and cancel it, and see. It's not a big deal -- only $1.20 to find out for sure.
