This, and other websites, have no relationship with market makers; they simply receive raw data (bid, ask, execution price) from agencies like Reuters. There is no indication in the raw data whether a trade was a buy or sell because market makers are under no obligation to release that information.
Some trades appear red/sell and some appear blue/buy simply because of how this website is programmed to present the data. When a trade is executed the price is compared to the mid-price between bid and ask. If the trade is executed below the mid-price, it is assumed to be a sell and displayed in red text. A trade displayed in blue text was executed above the mid-price.
The truth is a little dull compared to the intrigue of a good conspiracy theory. Of course you are free to carry on believing that the world is full of shadowy figures who are out to get you. It’s very fashionable these days.
