The premise of matchmaking transaction is that the buying price must be greater than or equal to the selling price. That is, the principle of price priority.

Matching price calculation method:

The premise of matchmaking transaction is that the buying price (a) must be greater than or equal to the selling price (b), that is, A> B. 。

Calculation basis: When matching, the computer actually determines the latest transaction price according to the previous transaction price.

Assume that the previous transaction price is C and the latest transaction price is D;

So, when?

A & lt=C，d = a； (If the previous transaction price is higher than or equal to the purchase price, the latest transaction price is the purchase price. )

B& gt； =C，d = b； (If the previous transaction price is lower than or equal to the selling price, the latest transaction price is the selling price. )

B& lt； C< when a, d = c; (If the previous transaction price is between the selling price and the buying price, the latest transaction price is the previous transaction price. )

Price advantage: it not only embodies fairness, but also makes the transaction price relatively continuous, avoiding unnecessary irregular jumps.
