Quote from yip1997:
Call diagonal is not as sound as the put diagonal, because it hurts by a vol drop. My rut call diagonal is at risk too, but since I made partial hedge when it was 20 points away from my short, I moved the be point to 771. 25% of my potential gain has evaporated today.

True, call diagonals are a little different than the puts as volatility works against you when the market pops like it has today. I decided against making an adjustment to my trade, I just got out (a sure sign that the market will drop 10+ points tomorrow).
The SPX was only about 5 points from my short and I was able to close out for a whopping $60 loss. On 2 of my trades I got fills that were .05/.10 better than the mid fairly quickly, ToS helped me out there I'm sure.

I've still got a put diagonal. I hear some bearlike growls off in the distance, I just hope they show up soon, like the next few days.
