I am selling strangles on SPX and NDX in Interactive Brokers. The thing is that I am really frustrated with these weird SPAN margin requirements. It is not only that the margin is too big, it's also that a lot of weird things are happening and I can give no explanation at all. For instance, today I was short 3 NDX March calls and I wanted to roll over my position to next month. I bought back the March calls but all of a sudden I couldn't sell even ONE of the April calls. Then I discovered that the only way I could sell the April options was if I was long an NDX future!!!!! Has anybody come through the same issues? Any potential solutions, margin friendly options brokers? I would appreciate any help
you should call your broker. they have the full picture regarding your account and can explain why you couldn't buy. my broker had a bug which wouldn't release margin properly sometimes. I would call them and they would override it.
