Aug SPY Buy-Write

SPY buy-write on Aug 96 Calls, one more dollar in the money cost only .4 in premium--seemed like reasonable insurance. Bought SPY at 97.43, sold Aug 96 Calls at 3.12, for net debit of 94.40. I screwed up with the debit order, incremented the wrong way (debit = debt dummy!) -- cost me around .12 -- argghh.
