Market makers use 24-hour trading (financial derivatives imitate London gold trading mode) and international synchronous quotation. Matchmaking is like shopping. You can't buy anything until you have something to sell. You can't sell it until you buy it. A market maker means you can buy whatever you want and sell whatever you want.

2. The matching system is 10 hour, which is delayed compared with the international gold price. Market maker means that real-time quotation and real-time trading adopt T+0 mode, and the market maker fair is relatively active and the risk is relatively high.

Matchmaking transaction refers to the transaction that both buyers and sellers must conduct at the same time, which also adopts T+0 mode, but the operation time may be relatively lagging behind.

3. The price of the matchmaking transaction is set by the participants, so each participant will directly affect the market; However, the price of market-making transactions is set by traders with certain strength, credibility and qualifications, and trading participants can only trade at the trading price set by traders.

4. In the market-making mode, dealers with good reputation need to unconditionally execute the transaction according to the quotation and ensure sufficient liquidity, and there is no case that the user's order is not closed or partially closed. Two different modes meet the needs of different users respectively.
