Using Interactive Brokers, I went long 1 June ES contract at 750. At the same time I wrote an April 800 call that expires today and should end up in the money by days end. Below is a suggestion I was given concerning my current situation. Does anyone know how it pertains to Interactive Brokers? "..... I don't know if you will end up with a long and a short e-mini in the same account after assignment or whether they will cancel each other out. If you don't want to pay exercise fees, you can close the positions yourself to lock in most of your profits."
