Key Levels S&P 500 13/12/2017

After the recent uptrend on the S&P 500, I prefer to wait for reversal.
If the price will break the confirmation zone, it indicates that the price tends to reach the demand below, and maybe the one at the bottom.
therefore if the price will break the confirmation zone, i'll look for P"A
Setup to sell, my first target will be the demand below, and the final target will be the demand at the bottom.
