RE: 500,000Seller here again.27 Sep 2023 10:55
Hopefully everyone using LSE discussion boards knows that isn't a list of 'buys and sells'. It's a list of trades sorted against the average/mid price of the various MMs at the time stamp of the trade. If the trade is below the mid then it's labelled as a 'sell', or above then it's labelled as a 'buy'. But if you look at actual trading ranges, and the Bid/Ask of different MMs you can quickly see that's not how it works in practice, it's just an estimate. At different periods of trading it can be more or less misleading (and there are ways of distorting it's appearance by putting through small trades at misleading prices, by delaying reporting of larger trades, and so on). HE1 trades on AIM SETSqx anyway, so prices also get uncrossed only at periodic auctions (and some orders are only visible for a 10 minute call period before each uncrossing). Basically, ignore the buy/sell labels or take them with a pinch of salt, especially on less volume traded shares.
