Extremely sloppy short-term chart patterns, and I was frankly fortunate I don't typically trade much in the last hour due to decreased focus (don't get me going on my deteriorating poker play after a long session) and from seeing occasional end-of-day chop like this at times. Still, the first green bar in the circle -- or even the one to the left of the circle -- could have signalled the beginning of a significant and consistent late-day squeeze. This time of course it didn't.
I'm still looking for that 100% probability trigger. It will be a long search.
