Foreign exchange transactions between large banks can account for 1/3 of market transactions, including professional foreign exchange banks and large commercial banks. Banks are sellers of foreign exchange transactions, and large commercial institutions, hedge funds and central banks are their main customers. Such as UBS, Barclays Bank, Deutsche Bank and Citibank.

2) Central banks of various countries

Central banks are special participants in the foreign exchange market, and their purpose of participating in the market is different from that of investors. Its purpose is to settle international trade, manage foreign exchange reserves and adjust exchange rates. The central bank is one of the major concerns of investors.

3) Commercial enterprises

The role of enterprises has little to do with the competition of ordinary investors. Large commercial companies enter the foreign exchange market mainly because of their business needs, and usually trade with commercial banks. For example, when Apple imports electronic equipment from Japan, it must exchange US dollars for Japanese yen.

4) Foreign exchange dealers

Foreign exchange dealers are also divided into brokers and market makers. Brokers are only intermediaries between ordinary investors and foreign exchange banks, and market makers will directly participate in foreign exchange transactions. Such participants have the closest relationship with individual investors.

5) Individual investors

Retail spot foreign exchange trading is actually aimed at individual investors, both retail investors and professional investors. From the perspective of the whole market, the trading share of such traders is not large, but there is a trend that more and more individuals begin to invest in foreign exchange.
