Wierd trading at the close in GRPN. Last 2mins. it trades from 22.50 all the way to 25 in 2 1min candles (see chart, chart is missing the close) But the stock closes at 23.04. Last two trades on bats are 16:00:06 23.55 200 15:59:52 24.58 100 [notice one dollar difference in two trades!] Does anyone have more info on what happened, because it seems a little disorderly. Doesnt seem normal to me
