Quote from atticus:
I'll what-if it a week forward or so at neutrality, assuming flat vol. I am looking for strike touches or a move in vol. The AAPL calendar I closed was a bet on a strike touch and a gain in vol. Unfortunately it inverted on delta but rose on vol.
How about the decision to bail on a loser - is that simply a function of stopping out of the trade if the marks go some multiple of the expected profit target against you? Or is the stopping out decision a separate process entirely?
