Appears to be in an island reversal. Watching for a breakaway gap from the box. Additionally, it appears the top of the box is a key level of previous support and resistance ($22.90 ish), with swing lows getting higher. My entry will be a gap up from this level with significant volume or after the break of resistance with a pullback to the $22.90 level confirming support.
Beware: WKHS is burning through cash and needs to raise again. Any bullish run will be a quick trade for me. A pump leading to an offering sounds realistic.
