Driving, every trade is a simultaneous buy & sell (see attached explanatory link). The LSE system of categorising a trade as a Buy or a Sell based on which side of the bid/offer midpoint a trade takes place, gives an entirely false impression of what is going on; by ignoring the fact that every trade it categorises as a 'Buy' is also a sell & every 'Sell' is also a buy. The key indicator of whether selling is overwhelming buying is the change in price level, yesterday selling pressure overwhelmed buyers & the price fell significantly vs the previous day reflecting that market reality.
This is the link from Investopedia, see section Stock Market Supply & demand :
https://www.investopedia.com/articles/investing/082614/how-stock-market-works.asp
"For every stock transaction, there must be a buyer and a seller. Because of the immutable laws of supply and demand, if there are more buyers for a specific stock than there are sellers of it, the stock price will trend up. Conversely, if there are more sellers of the stock than buyers, the price will trend down.
A trade transaction occurs either when a buyer accepts the asking price or a seller takes the bid price. If buyers outnumber sellers, they may be willing to raise their bids to acquire the stock. Therefore, sellers will ask higher prices for it, ratcheting the price up. If sellers outnumber buyers, they may be willing to accept lower offers for the stock, while buyers will also lower their bids, effectively forcing the price down."
