Here are hourly charts of the September S&P e-mini futures, the Spiders, and the QQQQ's. I last commented on these markets here.
The S&P's broke below the 1540 level briefly today but I think that the move will prove to be a false breakout. The action in the Q's which held their corresponding low reinforces this view. so I am expecting all three market to start a swing upward to the upside targets noted on the charts.
