The situation in call auction is related to the opening of the day and the operation of the stock price. Call auction is divided into three parts, one is the price change in call auction; The second is the number of matches; The third is mismatch. The price in call auction is at the top of the bidding chart, and the market has a strong willingness to buy. The price will be directly sealed, and the opening price will be a word board. Weak willingness to buy will be lower than yesterday's closing price, and it will go down all the way until the opening price is determined. Of course, the market is not optimistic about the day's market, and the bidding is also high and low, opening lower than yesterday's closing price. Sometimes the main force will use call auction to play tricks, first make an offer and then suddenly withdraw the order, so the price will go down. Therefore, it is necessary to consider the intention of the main force through call auction, combined with the commission sales of call auction to judge.
Consignment quantity is divided into matched consignment quantity and unmatched consignment quantity. Mismatched consignment is an upside-down red-green column in the middle of the call auction diagram. The inverted red column is the number of unmatched delegates, and the green column is the number of unmatched delegates. The more red columns are upside down, the stronger the market will buy. On the contrary, it shows that the market is willing to sell. The corresponding consignment quantity is in the lower part of the call auction chart. The more red bars, the longer the bars, and the more optimistic the market is about the market. On the contrary, the market is not optimistic about the market that day.
Call auction refers to the bidding method of one-time centralized matching of trading declarations received within a period of time. Taking China's bidding trading system as an example, the principle of determining the transaction price in call auction is:
1. Select the price with the largest transaction volume within the effective price range; 2. All buy declarations above the transaction price and sell declarations below the transaction price are closed; 3. At least one of the buyers or sellers with the same transaction price has completed the transaction.
If more than two prices meet the above conditions at the same time, the Shanghai Stock Exchange stipulates that the declared price that minimizes the transaction volume is the transaction price. If more than two declared prices still meet the requirements, the middle price shall be the transaction price. The Shenzhen Stock Exchange takes the price closest to the previous closing price as the transaction price. All transactions in call auction are made at the same price. Call auction did not clinch a deal part, automatically enter the continuous bidding.
