Tom. I tried it on the spx (where I have no experience whatsoever) and I think I know why I can't visualize your pnl profile. I was thinking of selling a higher strike in the back month after I buy back the short front month effectively turning an OTM call calendar into a long call vertical in the back month. I assume you are talking about turning a calendar into a short call vertical after buying back the short.. since you said "then sold the strike $5 closer to the market for 40¢"
So in my example w/ SPX at 2440, I would put on a 2475 calendar for $55 debit, wait for a pop to 2460, buy back the short 2475 suffering a~70cent loss , sell the back month 2480 for $1.75 .. the net net numbers mean that I bought the 2475/2480 vertical for a slight credit after adding in the 70 cent loss , giving me a 2475/2480 long call vertical in back month for slight credit ie no risk other than the initial $55 debit I took for the calendar. Am I still off?
