Take multiple orders as an example: if the price of limit pending orders is higher than the latest price, it is generally more than two orders higher than the latest price, and transactions are usually made in time at the latest current price, but the price of pending orders cannot be higher than the daily price limit, and pending orders can be placed within the daily price limit. This kind of pending order belongs to active buying. If it is passive buying, the price of pending orders will be lower than the latest price, for example, the highest price is 1980, then all pending orders below this current price are passive trading orders. This kind of pending order can only be traded if the price is adjusted back to this position.

The stock is empty, so is the pending order. However, the price limit pending order is only valid on the same day, and the system will automatically cancel the order the next day.
