That is not an after hour trade but cumulative trades that occurred during the day. There is no after hour trading with pinks. Looks more like people wanted in badly today.
what do you mean, those were buys, not sells, i can probably accurately account for at least 70?% or 90% of who was buying on this particular day........there may have been like 100,000 sells and the rest buys,
According to this site more buys than sells with most trading in the neutral zone.
