Is it true that the call auction is meant to prevent human manipulation?

Call auction refers to a one-time centralized auction method for the purchase and sale declarations received within a period of time. Taking China's auction trading system as an example, the principles for determining the transaction during the call auction are: 1. Select the price with the largest trading volume within the effective range; 2. The buy declaration higher than the transaction ** and the sell declaration lower than the transaction ** are all traded; 3. At least one of the buyers or sellers with the same transaction is fully concluded.

If two or more prices meet the above conditions, the Shanghai ** Exchange stipulates that the application with the smallest untraded volume shall be regarded as a transaction. If there are still more than two applications that meet the conditions, the middle price will be taken as the transaction. The Shenzhen ** exchange takes the nearest price from the previous ** price as the transaction price.

All transactions in the call auction are filled with the same **. The unfilled part of the call auction will automatically enter the continuous auction.

The so-called call auction is that before the opening of the day, you can enter ** according to the **price of the previous day and ** for the ** of the day**, enter all the orders of the computer host in the call auction time, and calculate the maximum volume according to the principle of **priority and time priority**, this ** will be the transaction of the call auction**, and this process is called call auction. After 9:25, you can see the transaction and quantity of each call auction.

Sometimes a certain ** cannot be completed because the **person gives ** lower than the ** given by the seller**, then, after 9:25 minutes, the column of the ** transaction price is empty. Of course, some companies stop trading for a period of time because they want to release news or hold a shareholders' meeting, so the transaction price column of the company's ** is also empty during the call auction.

Because the call auction is traded according to the maximum trading volume, for ordinary shareholders, at the call auction time, as long as the **** entered is higher than the actual transaction, the transaction can be traded, of course, if you buy at the limit price or sell at the limit price, the priority transaction is guaranteed. Therefore, if you want to buy first in the call auction, you can usually set the price higher, in order to get the right of first refusal, because your transaction price is a lower call auction. In addition, the number of ****** will not be very large, and it will generally not have any impact on the call auction of the **.

The pre-opening auction is a call auction, which is mainly used to determine the opening price of the market today. The reason why the opening price is generated by call auction is to prevent someone from manipulating the price and enhance the fairness.
