Hi Ish,
First thing that pops into view is your were trading DEC. We rolled to March on Thursday. Despite the volume drop, I think you did pretty well. It gets pretty easy in hindsight, huh? LOL.
I think you're right, the 3 strong green candles were definately a message. However, I think you managed correctly. Given that we only made it to 688.30 from the 689.60 entry, it would have been pretty agressive to have closed it out as it came back above 89. That would smack a little of "scared money" to be managing that tightly. I think you did it right in giving it some room to turn back south before rushing to exit. I don;t think a "once broken" play was appropriate in this case.
Losses are a part of trading. This is one that just didn't work. I like that you spotted the management that could have produced a better outcome but I think you did about as good as was REASONABLY possible.
