I read McMillan's OASI but he doesn't say much about spread selection. What criteria do you use when picking a vertical spread, other than the usual BEP and max profit analysis? How do you determine how wide the spread to go for? I want to do a conservative ITM bull spread on AAPL with high probability of ending up in profit at expiration. I checked out 65-75 for the long leg and 80-90 for the short leg. So far all the ITM spreads I checked out have poor risk / reward. Any inputs? Thanks!
