Read the small print on any trade reporting page and they will say the buy/sell column is only a representation of the trade based on the price and the stated advertised buy/sell prices at the time of the trade.
Now, to explain it as short as possible.
An MM has 3 minutes to report a trade.
During that time the price may move. When they report the trade the automated computer systems can register the trade wrongly......and the buy/sell data is only REPRESENTATION, its not accurate and nobody claims so.
EG. The advertised price is 180p sell and 185p buy. I buy 100,000 at 185p. The MM then moves the prices upwards to 185p to sell and 190p to buy. They then report my 100,000 trade at 185p. The automated systems then say ok thats 100,000 at 185p and therefore as buy and sell prices are 185p sell and 190p buy then that trade was a sell. It was not of course.
This is why MM's have 3 minutes to report a trade, it allows nobody to know what are real buys and sells in times of heavy trading.
They can also delay very large trades 1 hour.........and they can delay filled order reported until end of day when the fill or kill is completed.
So, you do not know if a trade is a buy or sell, you can guess, like the automated reporting guesses, but its wrong a lot of the time. Share price up.....buyers are dominant. Share price down then sellers are dominant. Thats the only sure thing.
