This is a main tracking system. With strong technical force, we can track every subtle movement of the main force of long and short, and reflect it in the form of signals. Users can follow the cell operation according to the signal prompt. The main mechanism version is divided into upper and lower parts with the central axis as the dividing line. Above the central axis, we define it as a market dominated by bulls, and any bull market is produced in a bull market. Below the central axis, we define it as a bear-dominated market, and any bull market is produced in a bear market. The purple body above the central axis is multi-headed. Generally, when bulls increase, the market will rise. The yellow box indicates that the bulls have closed their positions, but the closing amount is not large. The main force of similar actions is generally washing dishes or preparing for the next large-scale opening. Long positions or short positions should be carefully observed. After the yellow box, there will be a purple long position increase signal, or a large-scale long position green box signal. The green square is not only a signal of large-scale lightening of long positions, but also a signal of a large number of short positions entering the market. If a green square appears and crosses the central axis, it can be seen that the main force has officially turned into a short position, and generally there will be a big short position after that. The distance between the green square and the central axis indicates the current position of the short main force. When the red square appears behind the green square, it is a signal that the main short position is closed, and its nature is similar to that of the yellow square. If a blue column appears behind the red square, the bears begin to leave on a large scale. When the blue column is small, it turns into a white square, indicating that the market has returned to the main control of the bulls, and the big rising market will generally appear after this. We generally define the green square appearing above the central axis and the blue cylinder appearing below the central axis as two long-term competition areas. When major players compete for the market, the market generally fluctuates. Because the bull market in the futures market generally appears in the form of bands, it is difficult to grasp it in the form of rapid suppression compared with short positions. Our intervention in extracting the main long-term funds. The red horizontal line on the central axis is the signal that the main funds of the bulls enter the market. When the red bar appears, the market will definitely rise.
