I see what you're looking at now. It was trades from mid day that are now posting in AH trading. It states, 8000 shares at 12:30 p.m. and another 18700 shares at 12:17 p.m. and then the total of 26,700 shares cancelled during AH trading at 12:15 p.m.
Very odd because the cancelled time is before the executions of purchase. Maybe those times are listed in PST? Seems like an order correct if that's EST though.
