In the stock market, trading volume is an intuitive reference data indicator. Through the different changes of stock trading volume, different market information is given, which is helpful for investors' reference. Today, I will share with you a volume reference method-the over-the-top method. First of all, the form of excessive trading volume usually appears after the stock price has risen for a period of time, and the overall trend is on the rise. There is a trend callback or sideways adjustment state, which forms the top in the technical drawing. After callback or sideways, it rose again near the top high point of the previous period, making the volume in a relatively large state, and breaking through the top high price of the previous period, forming a pattern of excessive volume. In the technical form of high-volume overhead, the front top figure will be the upper line of the rectangle in the state of sideways adjustment or the vertex angle of the rising triangle figure formed after callback, which is one of the technical forms of upward breakthrough. Under normal circumstances, the form of excessive volume will form an effective pile state at the top of the previous stage, and the subsequent transaction volume will be greater when it breaks through the top of the previous stage for the second time. When the breakthrough occurs, the K-line is in the state of rising positive line or single positive line. In the process of observing the excessive volume of stocks by using technical forms, investors can observe that the stocks have moderate volume for several days in the second rise or have a huge breakthrough when they break through the top of the previous period, which can be used as a reference signal for buying technical forms. When the stock rises in the form of excessive volume, if the stock moving average is arranged in a bullish way, it will make the stock price break through the previous top position with great probability. When the stock forms a form of excessive volume, the pressure at the top of the previous period will be transformed into short-term technical support. Generally speaking, the pattern of excessive volume is the graph of the second rise of K-line, which is mainly driven by strong trading volume. However, investors should pay attention to the fact that there are no perfect technical indicators and technical forms in the market, and there will be some misleading information. I don't think technical graphics are almost blind transactions, but also need to be combined with other indicators, market environment and individual stocks for reference.
