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. )
