Blissful: My grid still displays 726K in the "Volume Bought".
If anyone should be interested in my correspondence with LSE regarding this issue, here you go:
My query today 18/06/2019 12:37:53
I am wondering why your automated/computerized trading system doesn’t take a
490,984 share purchase at a price of 7.34p into account, i.e. does not
display this purchase in the “Volume Bought” grid. This is the highest price
paid today (next to one other very small trade). Based on the purchase price
there is no doubt that it’s a purchase. Can you please give me reasoning why
this is so. And please: If the trading system were actually automated it
would have clearly defined this as a purchase. For the sake of market
transparency you may want to reconsider the programming of your “automated
system”.
Craig’s response (LSE) at 13.40:
We calculate the trade type based on the trade price being higher or lower than the mid price at the time of the transaction. Sometimes this calculation does not work, or the price is the opposite side of the mid price. This means we are either unable to calculate what type of trade this is at all, or the calculation shows it as the wrong type of trade (a buy instead of a sell for example).
Our method of calculating the type of trade is the industry standard, and while we are not provided by the type of trade from the stock market we will continue to use it as it's what the majority of websites use.
My response at 13.58:
Doesn’t it seem strange that this always and only happens with large volume trades (e.g. last week)? You guys are (or should be) professionals in a highly sensitive environment and still you don’t seem to be worried about this fact which clearly has a distorting effect.
Something is going wrong here. Do I understand correctly that you guys have no intention to look into this and make your system work in a manner which would (at least more closely) reflect reality?
Craig's response at 15.06 (continental European time):
Since all websites like ours use the same or a similar algorithm and since the Stock Exchange don't provide us with the data that tells us if it's a buy or sell then potentially inaccuracies will no doubt continue.
The fight for accurate data should be directed towards the Stock Exchange. They don't provide anyone with the correct information that tells us if it's a buy or sell, hence why we all use an algorithm that can at times be wrong.
My conclusion: Looks like we've just got to accept this lousy set up. It's a "love it or leave it" type of situation.
