If there is no transaction within half an hour after the opening of the market, the opening price of the previous day is the opening price of that day. Sometimes, if a security has not been traded for several days, the stock exchange will put forward a guiding price according to the price trend of the securities entrusted by customers as the opening price after trading.
2. The closing price refers to the transaction price of the last transaction of a certain kind of securities before the end of one-day trading activities on the stock exchange.

Precautions for buying stocks:
1, the trend law. Before preparing to buy stocks, we must first have a clear judgment on the running trend of the market. Generally speaking, most stocks follow the trend of the market. When the market is on the rise, it is easier to make a profit by buying stocks, and buying at the top is like pulling a tooth out of a tiger's mouth. It is difficult to survive in the downward trend, and there are not many buying opportunities in the market.
2. Batch rules. In the absence of full assurance, investors can buy in batches and in dispersion, which can greatly reduce the risk of buying. However, it is not advisable to buy too many types of stocks in a decentralized manner, and it is generally appropriate to buy less than 5 stocks. In addition, buying in batches should be implemented in a planned way according to your own investment strategy and capital situation.
3. The bottom line. The best time to buy stocks in the medium and long term should be in the bottom area or in the early stage when the stock price has just broken through the bottom. It should be said that this is the least risky time. Although there are opportunities for short-term operation every day, we should try to take into account the changes in short-term bottom and short-term trend, fast-forward and fast-out, and the amount of funds invested should not be too large.
4. Risk rules. The stock market is a high-risk and high-yield investment place. It can be said that risks are everywhere in the stock market and there is no way to completely avoid them. Investors should always keep risk awareness and minimize risks as much as possible. The timing of buying stocks is the first and most important step to control risks.
5. Strong rules. "The strong will always be strong and the weak will always be weak", which is an important law in the stock investment market. This law will guide investors to buy stocks.
6. Theme rules. In order to get more profits in the stock market, especially in a short time, it is very important to pay attention to the speculation of market themes and the conversion of themes. Although various themes emerge endlessly and change rapidly, they still have relative stability and certain regularity. As long as it is properly grasped, there will be rich returns.
7. Stop loss rules. Instead of passively locking up, it is better to take the initiative to stop loss, temporarily recognize compensation and wait and see. This is especially true for short-term operations, and stop loss can be said to be a magic weapon for short-term operations.
