that blue line is 38,connect tops from 2/07/11,no vol spike on that 37 print, this might be a day where they dont share,with all the sell orders up at 38
If you're an ES trader, this was one of the harder rallies to catch IMO. The price action was not clean, and every consolidation had the look of a drop rather than a pop. If you were able to take advantage of this trending day, you're an excellent trader IMO. b/c it fooled me.
