Quote from IV_Trader:
Risk , about conversions...looks like the best time to close (win or lose) position is around 2 weeks before exp when OTM (long) gamma starts collapsing very fast. Is this fact should be consider ?
I find delta position much more predictive than the rate of gamma-decay. The otm decay isn't going to decline rapidly as the position is lopsided on deltas. The near-wing will be peaking on gammas and the far wing is already depleted.
You're better-served with directional bias and static delta. I'd offset the fly at neutral-delta if vols have declined significantly.
