What do you mean, make a deal?
Matchmaking transaction refers to the trading mode in which the seller entrusts the sales order and the buyer entrusts the purchase order in the trading market. The trading market determines the trading price of both parties in accordance with the principle of price priority and time priority, generates an electronic trading contract, and makes physical delivery according to the delivery warehouse specified in the trading instruction. A necessary prerequisite for matchmaking transactions is that the declared purchase price must be greater than or equal to the selling price. When the purchase price is equal to the selling price, the transaction price is the purchase price or the selling price.
When the buying price is greater than the selling price, the latest transaction price is subject to the previous transaction price, and when the current transaction price is lower than or equal to the selling price, the latest transaction price is the selling price; When the current transaction price is higher than or equal to the purchase price, the latest transaction price is the purchase price; The previous transaction price is between the selling price and the buying price, so the latest transaction price is the previous transaction price.
Matchmaking has many unique advantages: while ensuring fairness, it can also make the transaction price relatively continuous and avoid unnecessary irregular jumps in the transaction price.
