PLUG - failed breakout vs. impending short squeeze?

PLUG with 80% volume shorted today with a bearish candle on the daily..

The question is whether this was a failed break out w/ an inverted H&S or a set up for a short squeeze into earnings?

4.71 resistance but appears to have found support at 4.31 near end of day trading.

Expect that if 4.29 can hold, holding CALLS into earnings seem like an attractive idea. Below that level likely means we re-test the trend line.
