RE: Orders on LSE with Buy/Sell marked "Unknown"26 Apr 2023 15:36
Hi DeffoTheLastSpin,
We calculate the trade type based on the trade price being higher or lower than the mid price at the time of the transaction. Sometimes this calculation does not work, or the price is the opposite side of the mid price. This means we are either unable to calculate what type of trade this is at all, or the calculation shows it as the wrong type of trade (a buy instead of a sell for example).
The above would explain why you sometimes see an Unknown trade. Delayed trades can happen from time to time, which can be due to various different reasons that we're not always told by the Stock Exchange.
