For example, the current pending order situation of a certain variety is: "selling price is 3350/32 lots" versus "buying price is 3349/ 19 lots", of which 32 lots and 19 lots are "selling 32 lots at 3350 but not trading" and "buying at 3349 but not trading" respectively, 65438.

If one (or several) traders hang out 10 lots at the price of 3350, then the sell order at the price of 3350 becomes 22 lots, because the trading volume has reached 10 lots. At this time, the latest price is 3350, and 20 lots were sold (buy 10 lots and sell 10 lots).

In addition, the purchase quantity has nothing to do with the instant purchase price. The buying quantity is "the number of open bills hanging on the disk", and there is no such term as "instant buying price", only "current (closed) price" or "latest (closed) price".
