Some Downside?

I think so, at least for the S&P and Dow, the Q's have already seen it.

 Yesterday's POMO complete in the white box and Primary Dealers levitate the market. Since we've had negative divergences on the opening gap up as I mentioned earlier this morning and a nasty divergence recently in the afternoon

The SPY is showing the same exact thing.

A closer look at the SPY this afternoon. From these charts, unless something changes pretty quick, we should be seeing some selling pressure soon.
