I am new to charting, so you are more than welcome to point out any mistakes. What I see is that it has a Bullish Pennant that resulted in a breakout to a much higher price. After that there is a downtrend which we are currently in.

What really makes me stick to the idea is the presence of a bearish engulfing on the weekly chart. You know its target is the previous low in a chart.
