Coach:
I'm not clear on what your trigger levels will be for adjusting diagonals. With verticals you consider adjusting the position when the index is about 15 points from the short strike.
Are you planning to use the same trigger for diagonals? If so, since most here are placing there diagonal short strikes closer, wouldn't this typically increase the number of adjustments made relative to verticals. On the call side since volatility typically decreases, there doesn't seem to be much advantage over verticals. Sure you can roll to November, but isn't there a school of thought that says if you wouldn't put on the rolled position by itself independent of your adjustment then you should just offset.
So on the call side I'm not sure I see much advantage to diagonals over verticals. On the put side, I think there are.
