RE: 1000000 Delayed Buy at 8.512 Jan 2024 13:29
How it's stated is simply down to what the ask and bid is at the time the trade is listed, it's automatic. The trade at 8.5 was right in the middle of the bid and ask at the time the trade was listed so the system marks it as unknown, however it was stated that the trade was from 1 hour earlier, when the ask was 8.5 so at that time it would have been shown as a buy.
Also it has not been possible to sell at 8.5 at any time today yet lol, so safe to say it was a buy.
