Ihub seems to disagree with you, lol.

"The Buy, Sell and ? columns - Where the 'Price' is closest to the 'Offer' price, the trade is considered a 'Buy'. Where it is closest to the 'Bid' price, the trade is considered to be a 'Sell'. Where it is dead centre between 'Bid' and 'Offer', it appears in the '?' column; this indicates that the trade cannot be identified as either a 'Buy' or a 'Sell'. "

Rounds up or down depending on what it is closest to. If the order is directly in the middle of the BID/ASK, then it goes in the "?Vol." column.
