Hello EliteTrader forum! I have been trying to create a Combo Order in IB that allows me to submit simultaneous market orders on two different instruments. I want to submit both as MKT orders. It appears that I am only allowed to submit as either REL + MKT or as LMT + MKT. Has anyone else experienced this or can tell me if it is possible to submit a simultaneous Market combo order on two different instruments? Many thanks!
