hi. i entered a $440-450 bull call spread when the stock was in the 430s and now it is at 443 but im in the negative. i should be in the profit right? the 440 calls i longed are up 2.4/share but the 450 calls i shorted are up 2.5/share so im down $10/contract. i don't get it. can someone explain this to me? thank you.
