However, in actual intraday trends, both long and short sides usually start to engage in a "battle" in the last 45 minutes. If the market rises from the last 35 minutes to 45 minutes, the final trend usually ends with an increase. The reason behind this is that at this time, the most investors participate in trading, and when the upward trend is clear, there will be a continuous stream of buying orders pouring into the stock market to push up the stock price. On the contrary, if the market falls during the last 45 to 35 minutes, it will also be difficult for the market to perform well in the future. In practical operation, if investors carefully observe and analyze, they will find that the changes from half an hour to 15 minutes before the closing of the market often have a certain impact on the opening of the second trading day and the trend of the first hour after the opening. This impact has a good guiding effect on short-term operations to a certain extent, and investors should pay attention to it. The techniques that investors need to master for watching the closing session can be summarized as follows. Under normal circumstances, there is a slight upward or downward trend in the closing session, which belongs to the correction of the closing session and has little practical significance; If the stock price of a certain stock is not in the rising stage and the trading volume is quite ordinary, but at the last moment of the market, one or several obviously high trading orders suddenly appear, causing the stock price to rise significantly, this situation generally means that the market maker is making a closing price, and investors can make a comprehensive judgment based on the following situations. (1) If the stock price trend is average or even falling within a day, but there is an increase in the last 10 minutes of trading, and the price volume relationship is ideal. The occurrence of this phenomenon is generally due to the good upward trend of the market, which leads to the passive follow-up of stock prices. (2) If the daily trend is normal and there is a significant increase or even a limit up in the last 15 minutes of trading, the stock may have sudden positive news or may be a bullish behavior by the market makers. For investors, they can generally determine their next actions based on the overall market trend. Normally, if the market trend is good, you can buy, but if the market trend is not good, you can participate in a small amount or not participate. (3) A sudden large buy order appears one minute before the close of the day, and adds a few cents or even 1 yuan or a few yuan to the current stock price level to pull the stock price to a high level, with the aim of saving funds and allowing the stock price to close at a higher or critical level. This trading technique deserves investors' attention and vigilance, as there is a high probability of a downward trend the next day. 2. Pay attention to the tail end effect. Investors need to pay attention to the overall trend of the market, especially in the last 30 minutes. If there is a rebound during the decline and then a downward turn, the market may fall continuously for 30 minutes in the closing session, which can have a significant impact; If the trend is upward in the last 30 minutes, it can almost become a foregone conclusion to close at a high point that day. It should be noted that this tail end effect can also be used for analyzing the market before noon closing. For investors, if they can determine that the trend at the end of the day is weakening, they need to be prepared to reduce their holdings accordingly; If it is confirmed that the trend is improving at the end of the day, investors can actively go long. 3. Pay attention to the "Monday Effect" and "Friday Effect". As for Monday's closing, whether the stock price closes at a positive or negative line has a significant impact on trading throughout the week, as the long (short) side often follows suit after winning the first battle. To be on the safe side, investors need to pay attention to this. As for Friday's closing, the impact on stock price changes is also significant. It not only reflects the results of the day's long and short wins, but also allows for the analysis and judgment of the week's long and short wins and losses. 4. Pay attention to the closing red market. If it is found that the market closes in the red at the end of the day, accompanied by a long bearish candlestick, this is a rebound after bottoming out and gaining support. It may be considered to follow up, and the next day it will mostly open high. Buying at the last minute can avoid daily risks. 5. Pay attention to the closing green of the market. If it is found that the market is closing green at the end of the day, accompanied by a long upper shadow line and heavy upward pressure, the position can be reduced appropriately, and the probability of opening low and moving low the next day is higher. 6. In the midst of a sharp rally at the end of the trading session, a corrective rebound began to appear, but it was pushed to its lowest point near the end of the market, indicating that the market advantage was biased towards the bears. For this trend, the next day's stock price usually opens lower or flat. It should be pointed out that the probability of the stock price falling the next day is relatively high, and investors need to be careful. If the stock price trend has been in a relatively strong state on that day, but there is a sharp decline in the last few minutes of the closing session, investors need to be particularly careful. Normally, if the stock price trend is average or even rising during a day, but there is a decline in the last few minutes of the closing session, it may be due to being dragged down by the overall market. Short term investors can take advantage of this trend and operate accordingly. If the daily trend is normal, but there is a significant drop in the last 15 minutes of trading, the stock may have a sudden bearish trend, or it may be a bearish behavior by the market makers. This situation requires analysis based on short-term trends, company fundamentals, etc., in order to determine whether to reduce or clear positions in the short term. If the short-term increase is too large and there is a significant decline, it is necessary to liquidate and observe. If a sudden large sell order appears one minute before the close of the day, causing the stock price to plummet to an extremely low level. The main purpose of doing so is generally twofold: firstly, to intimidate investors and make them sell their stocks; Secondly, it is to enable the stock price to open high and rise sharply the next day to enter the rising list, in order to attract investors' attention. Objectively speaking, the late trading suppression can generally be seen as a sign of a significant increase in stock prices the next day, and short-term operators should pay special attention to it. 8. A clear upward trend has already formed before the end of the trading session, but in the last 10 minutes of the session, there is a rush to buy, with a significant increase in trading volume and driving the stock price higher. This situation is usually driven by speculative short-term investors who are actively chasing the rise. In fact, the occurrence of this situation is very unfavorable for the next day's trend. Because after the stock price opens high the next day, there will be pressure for short-term profit taking. If this part of the selling cannot be digested, the upward trend will be difficult to sustain. Therefore, selling pressure usually emerges quickly after the high opening. 9. Generally, the closing time before noon is a time for both long and short sides to rest, during which both sides are fully prepared for the competition in the future market. The final struggle at the end of the previous market can already demonstrate the strength of both long and short positions, so investors can generally judge the future trend based on the correction at the end of the previous market. In terms of specific operational steps, investors first need to find the highest and lowest values of the previous stock price, and calculate the median value; Then compare the previous market closing value with the highest, lowest, and median values taken to determine its future trend. Generally speaking, if the closing value of the previous market is compared with the highest, lowest, and middle values, and the closing value of the previous market is between the highest and middle values, then the bulls in the closing market will be stronger than the bears, gradually strengthening or reaching new highs through oscillation. If the closing value of the previous market is compared with the highest, lowest, and middle values, and the closing value of the previous market is between the lowest and middle values, then the bearish side of the closing market will be stronger than the bullish side, gradually falling or hitting a new low in a volatile manner. 10. Some institutions in the stock market usually have their own information networks, which is very important in the emerging Chinese stock market. In the current stock market, a single message can sometimes cause significant changes in the stock market's ups and downs. Objectively speaking, the impact of news on the stock market is profound, and the various rumors that come with news can directly or indirectly affect the trend of the stock market. The usual time for news to spread is in the afternoon. Because the news that should have been announced after the market closed or in the newspapers the next day was often known to some well-informed people ahead of time, this resulted in a tray of people and goods or a desperate sell-off in the end of the day, causing some fluctuations in the stock market in the last half hour. This fluctuation includes both the general trend and individual stock market trends. For investors, as it is not possible to "observe the six directions and listen to all directions", they can take advantage of market changes to adopt corresponding strategies to avoid risks. In practical operation, in order to prevent falling into the trap set by the market makers during the closing session, investors need to start from the following points. (1) Check if there is a large trading volume to cooperate, close high (close low), if the trading volume is too small, the long (short) side will have no power; Excessive trading volume and multiple (short) parties buying (selling) goods are all traps. (2) Investors need to analyze the authenticity of rumors to see if there are any positive (negative) news or rumors that match. Based on high trading volume and bullish (bearish) news, it can be preliminarily confirmed that the market is bullish (bearish), and buying (selling) stocks may be considered. To avoid unnecessary losses, investors are advised to hold positions based on their own situation and avoid full position operations.
