Entry/play: volatility bar, shorting for ndl
Management: trailed stop down, but coulda shoulda tightened so I wouldn't have come back so deep into the day range. Or, in retrospect, if I was going to give it room, should have given it to vwap.
Psychology: The case of $55 burning a hole in my pocket. Greed. Waste of $14 that I lost.
UPDATE/Lesson: after 11:00 spike down, it ran back to highs. Upon re-study of this trade, don't regret getting out. Only learn to tighten stop on ndl so I don't run so deep back through it.
