RE: MM trading @ sell prices....24 Mar 2021 15:10
Although they are contributing to the data do not think that MMs are actually setting the ASK & BID as quoted on AIM trading system. Also although 7 MMs are registered to trade in 88E not all are choosing to be active, probably the reason for out of kilter pricing.
"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.
If Mid Price, Mid High, Mid Low, Bid and Offer tags/labels are filled with values, this means that an order or quote has been published even if no trades (coming from on-book or off-book orders) have been executed yet, as occurred in the past days for 88 Energy Limited (only had off-book trades but there were on-book orders or quotes)."
