The market is acting just like it did in late Jan-early Feb after the first touch around 2300. 35-36 pt pullback before the ramp. I'd probably watch closely when ES gets down around 2365-66 (the exact level you mentioned), plus that would be a re-test of the SPX breakout level.
It definitely does have a "heavy" feel to it that you only see when too many are long (as opposed to the endless squeeze/momentum buyers) of the last month.
Open gap and short term trendline in the 65 area. What has to be watched is if we bounce from 65 area then I want to see sellers come back in around 83 in order for more downside continuation.
