Is it time for a pullback on the /ES?

The /ES has certainly been pretty strong and active. Looking at the upcoming week, I will be looking for a reversal going into a pullback. Why? I have taken a channel from the latest gains and placed it at the latest similar recovery. I am not saying we are due for a reversal next but exhaustion has to be coming into the minds of other investors. Also, I set up an approximate, by Fibonacci retracement, to see where I would possibly be comfortable buying if I see enough relief on the Stoch RSI.
