1) The standard perfect trumpet has three high points and two bottom points. These three high points are higher than each other, and the middle two low points are lower than each other. When the stock price falls from the third high point and its low point is lower than the previous low point, it can be considered that the form is established. Trumpets, like the shoulders above the head, belong to&; Ldquo turns at five o'clock &; Rdquo Therefore, the gentle trumpet shape can also be regarded as the head and shoulder top trend with high right shoulder and downward sloping neckline. Of course, in actual combat, you can't be dogmatic, you can't follow the script, and you can accurately judge by mastering the principles and mechanisms;

2) In terms of volume, the trumpet shape maintains a high and irregular volume in the whole process of forming the body, and does not decrease with the development of the body;

3) The shape may also break through upwards, especially at the top of the horn, which is connected by two high points of the same level. The trading volume of the third exploration is extremely shrinking, and then the stock price breaks through upwards with high trading volume (the closing price exceeds the resistance level by 3%), so the initial expected analytical significance of this shape will be revised, indicating that the upward trend will continue and the future increase will be considerable;

4) There is no formula for calculating the minimum decline in this form to estimate the future decline, but generally speaking, the decline is very large;

5) The downward breakthrough does not need to be re-matched, as long as it falls below the following two points, it can be confirmed;
