The directional volume (DMI) shows average volume has been low and the green line has just crossed up over the red, indicating a rise in buying.
Today shows a nice follow through after a move over the 20sma and two days of consolidation that stayed over the 10sma.
Most importantly, RSI crossed over 50, came back to test it, and today is higher again. This along with a trade over the high from Aug.5, trigger calls.
