The formal platform for speculating foreign exchange in China is banks, and the central bank is responsible for issuing money, controlling the money supply, holding and dispatching foreign exchange reserves, and maintaining the internal and external value of money. Under the floating exchange rate system, the central bank is often forced to buy or sell foreign exchange to intervene in the foreign exchange market and maintain market order. In addition to banks, foreign exchange speculation platforms include British CDK Chinese service providers, Nord, Fuhui Fuhui and Jiasheng; Domestic investors can also choose the Hong Kong platform across a river for trading.

Foreign exchange margin trading means that investors use the trust provided by banks or brokers to conduct foreign exchange transactions. It makes full use of the principle of leveraged investment, and it is a long-term foreign exchange transaction between financial institutions and between financial institutions and investors. At present, the country has not promulgated any laws on foreign exchange, so countries in the legal gray area have neither allowed nor forcibly prohibited it.

The leverage ratio of foreign exchange margin trading of domestic banks is relatively low, generally only about 10 times. Some banks don't even have leverage in foreign exchange leveraged transactions, and domestic banks have relatively high spreads and high handling fees.

All domestic platforms that can open accounts and trade are agents of foreign traders. However, as long as it is a regulated formal platform, traders don't have to worry about whether it is legal, because traders of these platforms have strict supervision abroad, and if there are any violations of laws and regulations, they can revoke their licenses overseas. In addition, China countries do not interfere with citizens' personal investment behavior, and choose foreign exchange accounts opened on foreign platforms for trading, and trading behavior also occurs abroad.
