Foreign exchange brokers only play an intermediary role in the foreign exchange market in order to earn commissions. Their main task is to provide correct and rapid trading information to promote the smooth progress of foreign exchange transactions and negotiate exchange agreements on behalf of customers. They belong to buyers and sellers, who directly or indirectly buy and sell in banks through the contact of foreign exchange brokers.

Market maker refers to an independent securities business legal person with certain strength and credibility as a chartered dealer in the securities market, constantly quoting the buying and selling price of a certain securities to public investors (that is, two-way quotation), accepting the buying and selling requirements of public investors at this price, and trading securities with investors with their own funds and securities. Buyers and sellers do not need to wait for the counterparty to appear, as long as a market maker comes forward to undertake the counterparty, a transaction can be reached.

Real market makers should include two levels: the first level is the retail market between market makers and investors, and the second level is the wholesale market between market makers and market makers.

The selection of market makers is relatively strict, and only those businesses with standardized operation, strong capital strength, large scale, familiarity with market operation and strong risk self-control ability can bear the responsibility.

The profit of market makers comes from the spread added to customers and also from the losses of some customers. As the name implies, a market maker is to create a trading market and provide customers with an artificially set exchange rate. Because it controls prices, customers will not see direct interbank market quotations. However, the competition among brokers is so fierce that the quotations of market makers are almost the same as those of other types of brokers.
