Second, the concepts involved:
1, opening price:
1) the opening price, also known as the opening price, refers to the transaction price of the first transaction per share after the opening of the stock exchange on each trading day. Most stock exchanges in the world adopt the principle of maximum turnover to determine the opening price.
2) If a security has not been bought or sold within a period of time (usually half an hour) after the opening of the market, the closing price of the previous day shall be taken as the opening price of the security on that day. If a security has not been traded for several days in a row, the on-site intermediary broker of the stock exchange will put forward a guiding price according to the price trend of the securities entrusted by customers, making it the opening price after the securities are traded. In the intangible trading market, if a security has not been traded for several days in a row, the closing price of the previous day is taken as its opening price.
2. Closing price:
1) The closing price refers to the closing price of the stock market, which is the weighted average price of all transactions (including the last transaction) one minute before the last transaction of the securities on that day. If there is no transaction on that day, the previous closing price is the closing price of that day. The closing price of Shenzhen Stock Exchange was generated by call auction. If the closing price of call auction cannot be generated, the closing price is the weighted average price of all transactions (including the last transaction) one minute before the last transaction of the securities on that day. If there is no deal on that day, the closing price of the previous day is the closing price of that day.
2) The closing price is the price recognized by market participants and accepted by everyone within one day. The highest price is the selling price that most people think is good, the lowest price is the buying price that most people think is good, and the closing price is the price that is no longer traded. Therefore, the judgment of closing price is of great significance. No matter how the stock price fluctuates that day, it will eventually be fixed at the closing price. Some people say that the main force can make a closing price with its financial strength, which is true, but it is more difficult for the main force to make a weekly closing price, especially a monthly closing price, because the cost is very high. From this point of view, the closing prices of the monthly and weekly lines are the most significant. Smart main players will use their own funds to fan the flames, rather than relying entirely on their own real money to make the closing price.
