On Balance Volume has been (bullishly) diverging from price since May indicating that "smart money" has likely been accumulating.
ADX is a level that implies a trend and D+ crossing D- indicates that it is bullish.
Recently we see price test the .236 Fibonacci level on higher than average daily volume days after gapping up and possibly changing trend (higher low, with volume)
Currently price sits at a possible double top, in the event that it cannot close above $4.05.
The chart looks bullish if price can break the $4.05-$4.13 level, with volume.
