Actually the system doesn't know whether a trade is a buy or a sell. It simply decides based on the price. If the trade price is below the mid-price, the system identifies the trade as a sell and vice versa. When the trade price is exactly mid way, the system can't tell. In fact, I have put through trades where the system has incorrectly marked as a buy or sell because my broker has gotten me either a good buy price below the mid or vice versa. So not all trades are market correctly. Hope that helps!
