The London Stock Exchange does not disclose whether a trade is a buy or a sell so this data is estimated based on the trade price received and the LSE-quoted mid-price at the point the trade is placed. It should only be considered an indication and not a recommendation.

Trades priced above the mid-price at the time the trade is placed are labelled as a buy; those priced below the mid-price are sells; and those priced close to the mid-price or declared late are labelled 'N/A'.
