Yep, also too much is put into the "Buy/Sell" indicator. All it shows is trades at the bid as sells and at the ask as buys, in between as unknown. It is a good approximation but far from what it is touted as.
See those whopper "T" trades at the top for ~14million shares, those are a very good sign of dilution if they occur often it is pretty much 100% although with this stock it is pretty safe to say shares are being dumped.
