04/11 EWZ Double Diagonal

EWZ decided to go wild as soon as I placed the trade. Notice we had a lot of up-days, now beyond 1.5 st. deviation on the volatility cone. The one thing I noticed is the difference between the Double-Diagonal and the 45-Day condor, notice the condor is down almost 10% with price still inside 1 st. deviation, the double-diagonal is losing 12% with price beyond 1.5 st. deviation on the cone..

Note: We are super close to the adjustment level 65% chance of hitting it Monday. One could have adjusted at end of day on Thursday, I wasn't monitoring the position, and even if I was, chances are I would not have touched. I'm tired of messing around and deviating from my plan. the purpose of this blog is to keep me honest, I put the plan in place and follow it, results and experience will tell me what to adjust on the plan, that simple.

Volatility has dropped by quite a bit, but the trade was originally structured to not have much vega risk, so it isn't hurting, in fact it might have helped the position early on.
