Quote from skeweddude:
I guess I will quote myself in the hope that this can be answered as well. I have another broker that does permit exercising long options to be used as taking responsibility for of assigned shares. This would truly only apply to me during early assignment, and the likelihood that likelihood is fairly low, but I would just like to know:
Is it not possible to exercise the 45 call in the morning when I have been assigned and sell that now owned stock originating from the exercise to satisfy the obligation at IB? I realize that I have ten minutes to do so or they get bought for me, and I read this in user's guide: The exercised option appears in the Outstanding Exercises portion of the window until it is cleared by the OCC. I am guessing the system does not recognize this and will take action if I have not?
