If you are letting an ITM spread go to expiration don't you have exercise fees for each leg? Mine would be 15$ per leg which would wipe out profits for 2 of those spreads.
I dunno...I always settle ITM positions before expiration. My options fee is 1.50 per lot so I would have to have on 11 spreads before it would be cheaper to let them expire.
I am trading Interactive brokers at the moment and there are no expiration fees!
