RE: Half-Year Trading Statement possibly tomorrow15 Mar 2024 22:46
I’ve managed to review a full list of the trades reported yesterday by cross checking data from 3 sources.
The total value of all those trades was £856,020. Compare that to the totals that you mentioned earlier - Buy £104,891 + Sell £151,938 = £256,829. The difference matches the total of the trades marked as ‘unknown’ - £599,191 = 70% of all trades by value not classified by LSE! It's the same % split for volume as well.
Most of those trades are ‘unknown’ because they were on mid price. LSE, and other similar websites, just run an algo on their database to match the trade price to the mid price at the time of the trade. If below they guess it was a ‘sell’, if above it’s a ‘buy’, and so any bang on the mid price have to be ‘unknown’ based on that limited methodology. Sometimes you can both buy and sell below, or above, mid price depending on availability of stock and the demand/desire of MMs to get rid of it – you can sometimes tell what the real active spread is by looking at the trade prices going through.
There were also two trades after close yesterday marked as unknown which is the LSE default for all late reported trades regardless of the price and spread. Same applies to trades above ask or below bid in the reported spread. There are exceptions to this which have appeared more and more recently so I suspect their algo is maybe a bit broken.
Buy and sell, i.e. the origin of the trade, are never reported by the market, it just reports that ‘a trade’ has occurred. Which is correct because there are two sides to every trade – you can’t buy unless someone else is willing to sell at an agreed price, or has already sold to an MM or other intermediary, and vice versa. So the whole concept of marking buy and sell is flawed to begin with. It’s just a tool that some data service websites like this one think will be of use to their members, without highlighting the limitations of it. And then it gets misused by rampers and derampers alike to mislead and suck in unknowing PIs on some shares.
So you can see that some of the trade info on here, other than the specific details that are reported by the stock exchange, has limited value as it can be unreliable unless you know what to look for.
Best wishes for a breakout over £12 – Half Year results on 26th might be the catalyst for that and I wouldn’t be surprised if there is a half-decent rise into that date, despite the lack of detail in the January update. We can only hope...
