piscio, whether a trade gets printed as a buy or a sell is automatically decided by an algorithm based upon whether it is above or below the mid price, therefore officially MMs cannot affect this, however what they can do is show an advertised spread and adjust the actual live prices to print buys as sells and vice versa, this can be very frustrating................. . A delayed trade can be conducted in one spread, however printed in another so you need to look at the spread at the actual timestamp and the trades around that time to determine whether it was a buy or sell. Hope that helps.
