Everyone - LSE’s algo isn’t smart enough to determine correctly if a trade is a buy or a sell. All it does is compare the trade to the mid price at the time of execution and if it’s below, determines the trade as a sell and if above, a buy. If the trade is exactly on the mid price it’s ‘unknown’
In real life buys can be below the mid (I know as it happened to me this morning on a top up) and show as a sell and vice versa if a sell happens to take place above the mid price.
