S&P - Simplest most effective harmonic

The simplest harmonic pattern there is that everybody knows about is the ABCD, so i've been told. The precision is fantastic, CD leg forming a doji and an engulfing pattern exactly at the 100% projection of AB. This for me looks really bearish. Depending on tommorow's NFP, or today in my timezone, I am looking for a short. I don't know if this is a start of a trend reverseal, probably not, everybody is talking about how the ending months of the year should be good for stocks, but it is probably a start for a correction. Maybe after tommorow's data, we will have a clear view, cause what happend today with the ecb, gold, yen, stocks was way more than i can comprehend.
