Market maker is a company that works on the exchange under the contract and provides liquidity in the #market .
There are market makers on the securities market, forex and #crypto market. It is an organization that has a large stock of an asset and cooperates with the trading floor. A #marketmaker undertakes to constantly buy and sell an asset in the volumes agreed upon with the exchange.
The essence of the market maker's work is to level out the difference between supply and demand. Therefore, when the market is in a strong upward or downward #trend , the market maker is forced to go against the market to provide liquidity. That is, when everyone is buying, the market maker is selling and vice versa.
Several market makers can work on one trading floor. And for them to perform their function effectively, the #exchange provides them with all information about traders' transactions (stop-loss, take-profit, pending orders).
