NDX Double Diagonal

My plan was to open up a new MNX double diagonal around today. Instead, I decided to save commission costs and open up a NDX instead. Today was my first ever trade in NDX. I got filled right at the midpoint instantly on a 4-legged trade...I guess I should have held out for more! Nothing fancy here. Will manage the same way as the MNX. Will roll up/down shorts to next strike when I get to 1505 or 1295.

Here's how the MNX double diagonal is looking. We had a low of 139.49 today, with the lower adjustment point at 137.00. Very, very close. We closed at 141.15, so the adjustment point is only a 1.7 daily standard deviations move down. It could happen at any time, and that's why I have a contingent order set to trigger at 137.00. Simply buy a 137.5-135 put vertical a few cents above mid price.

Lastly, I was able to buy the remainder of my RUT iron condors 580-590 call verticals for $0.20. This leaves me with all the puts and therefore fairly long delta. With the move down over the last few days, this position is down only about 4%. I'm hesitant about re-selling some calls...not without a day or two of upward movement first. And if I do resell, I'd only sell about half of the original amount at no more than a 10 delta on the short strike.
