Call auction, how to determine the transaction price. All transactions in call auction closed at the same price at 9: 25, the opening price. During call auction, virtual transactions are displayed, so the number of transactions is zero, so as to match a price with the largest turnover. If new buyers and sellers are added, a match will be made every ten seconds, and the displayed result is the maximum transaction amount of the price, but the number of transactions is zero. At this time, the price is generally changing, and the maximum turnover, that is, the quantity on hand, is gradually increasing, because only under the matching of this price, its turnover is larger than the previous one. It can replace the final transaction price, but if it is cancelled, the maximum transaction volume may also be reduced. 9: 25 is the only real transaction in call auction, so the number of transactions will be displayed. Of course, you can suspend or cancel the bill during this period, but you are not allowed to cancel the bill from 9: 20 to 9: 25. It is best not to cancel the bill when you are in call auction, and the probability of success is very small. Although it is allowed to cancel bills, there are many other reasons that make it difficult to cancel bills.
So if you want to buy a stock, you can buy it directly at the daily limit. If you want to sell a stock, you can directly hang the daily limit, so you can basically buy or sell it, but its actual transaction price is not the daily limit or the daily limit, but the closing price at 9: 25, which is the opening price. Everyone's transaction price is the same price, which is subject to the maximum transaction. Of course, if you open the market at the daily limit and the daily limit, you may not be able to buy it, because during call auction, the price is the first priority, the time is the second priority, the quantity is the third priority, the continuous bidding period is not the priority, and all the time before 9: 00 15 is the same time, so the pending time is the same.
Call auction sorts the buying price from high to low and the selling price from low to high, and then matches them from top to bottom according to the serial number until the buying price is the same or the selling price is higher than the buying price, then stops matching and selects a price that meets all the matching requirements. Finally, the current matching price and transaction volume are displayed, but the number of transactions is zero, because it is only matching and there is no actual transaction. If there are actual transactions, the number of transactions will be displayed, which is the number of transactions in the trading period and the number of transactions is large. For example, if you buy six transactions and sell eight transactions, the number of transactions will be displayed as eight. If there is only one purchase and one hundred transactions, it is a large purchase for the main force, and vice versa.
In call auction, the principles of determining the transaction price are: ① the price that can achieve the maximum transaction; (2) The transaction price of all buy declarations above this price and sell declarations below this price; ③ The price at which at least one of the buyers or sellers with the same price completes the transaction. If more than two declared prices meet the above conditions, the declared price with the smallest turnover shall be the transaction price; If there are still more than two declared prices to minimize the transaction volume, the middle price shall be the transaction price.
