Quote from dagnyt:
I closed a bunch of diagonal put spreads (my call positions are all ok, because I own some extra calls) for two reasons: One the profit was good enough to tempt me. But, more importantly, the market was running away from the strikes.
I open these spread for a credit. As time passes and if the market does not run towards the strikes (too quickly) then the spread revalues and enables me to close for another cash credit. That's the good news.
But, that cash credit can dwindle when the market rallies because the position's delta moves from positive to negative and because IV decreases. One way to protect the available credit is to grab it before it disappears. That's what I do.

I use a different approach. When delta moves from positive to negative, I will add another put diagonal to adjust the delta to my comfort zone (not neural). Since I open the new diagonal with a better IV (smaller IV), I have a chance of getting a bigger profit.
I didn't want to close all my diagonals because it meant i didn't get my target profit (because closing at smaller IV = smaller profit).
I don't know which is a better approach. It is interesting to compare these two approaches. Any comments on the pros and cons?
