I've been watching this for several weeks. The flags on this chart indicates anomalies between price action and volume indicating to me Insider buying. I've noted quite a few in past weeks. As it approached resistance I anticipated a pull back especially since it coincided with media reports of AA getting pulled from the Dow 30. It popped over a long established resistance line and then pulled back to support, forming a high base. Today confirmed the BO. I think this has legs. The candle, marubozu, is bulllsh going into tomorrow, This is supported by the 1 hr charts that show three subsequent advances supported with increasing volume at the end of the day.
