I55 not sure if the MM is able to influence the buy/sell flag, it is just an algorithm in the London Stock Exchange system.
Buy or Sell?
"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’. "

"The 88 Energy Limited (TIDM : 88E) is trading under the ASQ1 trading segment. So as per the below rule which we have agreed with our business, we have to consider the Mid values for this segment.
Rule:
For instruments with segment different from ("SET0", "SET1", "SET2", "SET3", "STMM", "SSMM", "AMSM", "SSMU", "ETFS", "ETF2", "ETFU", "ETCS", "ETC2", "ETCU", "IECF", "EUE2")
o The “Mid Price” ((bid + offer)/2) is the summary price and high, low, net change and % change are based on it.
Therefore, the below tags/labels (in the summary table) are considered for 88 Energy Limited as it is coming under ASQ1 segment.
Mid Price ? is calculated as the average of the values of the on-book BBO as Bid + Offer / 2. Considering only on book order/quote.
Mid High ? is an intraday data and represent the maximum value of the Mid Price(Considering only on-book order/quotes).
Mid Low ? is an intraday data and represent the minimum value of the Mid Price (Considering only on-book order/quotes).
Bid ? Best buy Price. Considering only on-book order/quotes.
Offer ? Best offer price. Considering only on-book order/quotes.
