And ... there goes my short delta. This setup started out at around -60 delta/contract, but with movement toward and then substantially through the short put, it's shrunken to -13.69, so it's not providing the amount of pro it did at the outset. By the same token, it finished the day at 65.45, 1.55 short of 67.00 max, so it's done some decent leg work in the sell-off. Will look to pull this off at 66.50 if I'm afforded the opportunity and then re-up (preferably on strength).
