-The "advance bill" in stock market transactions is a transaction form that is estimated in advance, filled in in advance and submitted to the securities business department first. This kind of transaction in the stock market has an image metaphor: what is sold at a high level is called "hanging basket"; Buying at a low level is called "burying mines".

For example, if you have a stock 100 lots and the current price is 10, then you can embed 10. 1 20 lots,120 lots in 0.2 yuan. . . Wait, so you can sell your stock at the price you set at any time, without having to fill in the price and quantity in a hurry. Similarly, if the price of a stock is 10 yuan, and you think it will stabilize until it falls to 9.6-9.7 yuan, then you can embed 50 lots of 9.65 yuan, 50 lots of 9.6 yuan and so on.

Prepaid bills are mainly used by institutions and people with large funds, and have little significance to retail investors.

If the stock with the advance payment is hung, buy or sell it when its price rises to the paid unit price, and vice versa. Even if the stock price rises to the buried price, it will not trade.
