Thicker the lines, stronger the cluster. PA is making it's way up to take out some of the upper support clusters, after taking out the initial one, I'd be looking for PA to reverse down somewhere between that cluster and the upper ones.
***** HOW TO READ THE CHART: The red and blue lines represent clusters of BUY/SELL orders. The thicker the line, the stronger the cluster. Red = SELL, Blue = BUY. Grayed Out = Cluster Hit & Gone.
