That is to say, if you lose a price, for example, the current price is 10 yuan, and you want to buy more when the price rises to 7 yuan, then you can enter 8 at a fixed price. When the price falls to 8 yuan, the system will automatically help you buy it, so you don't have to wait in front of the computer.

This way of placing orders is also called pending order transaction, or price transaction. You can make multiple orders or empty orders.
