Don't quote me, but I believe some trade streams record it as a buy if the printed price is closer to the (higher) ask than it is to the (lower) bid, and a sell if closer to the bid, from the spread at the time of the trade. Alternatively I think of it that the trade is a buy if an investor acquired the equity from a market maker, and a sell if an investor sold their stake to a market maker, I would have thought that definition would make buy vs sell unambiguous to the stock exchange. Perhaps someone else can elaborate, if this is not right.
