What period are those numbers from?
And are you basing those sums on the way trades are indicated (as red for sold, and blue for bought on the LSE site.)
- If this is the case, then unfortunately this is mostly wrong: the actual bid and ask of real trades can be both above or both below the middle indicated by the advertised prices (I.e. what you see higher up this page).
So in reality, to know if a trade logged is a buy or a sell is impossible to know for sure, you have to compare a transaction’s SP with that of the trades just before and just after to get an idea.
