EDIT: Achtung! Large player today (behind curtain trades)
EDIT: VWAP prior to that was $1.74635 so I suspect someone accumulating to satisfy a "good" customer as buy percentage advanced:
12:45: buy 41.56%, sell 49.75%, unk 08.69% on 318.9K
13:00: buy 41.41%, sell 50.02%, unk 08.57% on 323.5K
13:15: buy 44.74%, sell 48.35%, unk 06.91% on 479.8K
13:03, after a no-trade two minutes, did ~151.8K $1.75->$1.79->$1.76, including trades of $1.75 x 66,683, $1.78 x 42,360, and $1.79 x 15,770. But there were so many trades that average trade size was 2,663. This minute represented 47.27% of all prior volume and xx.xx% of the day's total volume.
