Looks like multiple stop-losses got triggered, especially from 35c down (new orders 1-2s apart cascaded down to 32c).
My data provider for my charting software doesn't update for another hour, but we've bounced hard off the 32c resistance, and I'm expecting a close at or near 38c which is the middle of the Andrews Pitchfork we've been in for a long time.
I'll post a chart once I get a data update showing this morning's interest :)
