While none of these sell signals have occurred yet, the following would likely trigger a correction to at least the 210.83 level on SPY & 108.82 on QQQ:
1) A break below the rising wedge
2) MACD 9-ema cross below the zero line
3) bearish cross on the 14/34 ema pair histogram

Based on where prices closed today in proximity to the apex of the wedge, if these patterns are going to play out for a correction, the breakdowns will likely occur tomorrow.
