I am short the 1155 calls on the ES. I decided if ES crosses 1155 I'll buy the futures instead of covering the calls. My question is: Do I buy the jun futures or the may futures? May futures expire next Friday w/ the options. That's when I get a little confused because let's say the ES closes at 1156 (may futures) on next Friday's expiration. The option I sold would be in the money by 1 point. But since the june futures trades at about 5 points less my option would then be out of the money. Can someone please explain? I never had this happened to me before.
