C2 is not netting the margin for short straddles. In particular I was trying to put an SPY straddle, but the system calculates each leg’s margin individually an do not net so it is basically demanding 2 times the margin required in real accounts. According to CBOE, margin for a straddle is almost the same as for a single call or put. This is of course also true in Interactive Brokers and I would assume in other brokers.
Please email me the systemid and the exact multi-legged trade you were trying to place. We do actually try to recognize straddles, so I’m curious what happened here. Send info to firstname.lastname@example.org and I’ll look into it. Thanks
Thank you. I’ve sent an email yesterday but still no answer.
Is it possible to simulate the margin requirement before trading? I can’t find the required margin in the trade entry screen. I can only see it when an order is rejected because of low margin.
