Foreign exchange platforms can be divided into broad and chivalrous names. Generalized foreign exchange platforms are places to provide transactions, including the concept of foreign exchange market. Chivalrous foreign exchange platform refers to some independent traders with certain strength and credibility in the foreign exchange market, who constantly quote the buying and selling price of currency to investors (that is, two-way quotation) and accept the buying and selling requirements of investors at this price. The platform can hold its own funds to trade with investors. When the market transactions are sparse, buyers and sellers do not need to wait for the counterparty to appear, as long as there is a "counterparty" to undertake the transaction, they can reach a transaction. This will form an uninterrupted business and maintain the liquidity of the market.
