the marging requirements for option seems time related or strike related. IB does not ask me for margin for OTM in friday expiration, for ITM on friday, I need a margin. that makes trading ITM on expiration day not desirable.
like AAPL/goog, they ask more than 20k. gee, better trade AAPL/GOOG directly
