Short CALL (OCT) at 10000, receiving 400 premium Long CALL (NOV) at 10000, paying 500 premium. At the expired date for OCT, If price closes at 9000, and I close all contacts, then Short CALL (OCT) at 10000, which would become 0 Long CALL (NOV) at 10000, for the worst case, do I lose maximum (400 - 500) = $100? If price closes at 11000, and I close all contacts, then Short CALL (OCT) at 10000, which would gain 1000 points Long CALL (NOV) at 10000, which would lose 1000 points which would cancel each other without risk? for the best case, do I gain maximum (500 - 400) = $100? Does anyone have any suggestions? Thanks in advance for any suggestions
