BABA Found Bottom? Reversal Head and Shoulders Play to $210

On the weekly chart, $BABA looks like it has found support at $155 and is forming a reverse head and shoulders pattern. I'm looking for one more touch of $155 or slightly lower, followed by a close above the $155 support to start adding a long position. A break above the downward resistance trendline would confirm a bullish break upward and $180 giving us our next big resistance. A close above $180 should send this back to $210.
