The white line is the short-term main operation trajectory, the yellow line is the medium-term main operation trajectory, and the purple line is the long-term main operation trajectory. 1, the white line of the main import and export index breaks through the yellow line and the purple line upwards, and the three lines diverge upwards, indicating that the main force can effectively control the market, can intervene at the bottom, and its shareholding is waiting to rise. 2. The white line of the main import and export indicators rises too fast and is far away from the yellow and purple line, which shows that there are many short-term profit chips, so we should pay attention to controlling risks and selling them appropriately. 3. When the white line falls back to the yellow-purple line and the yellow-purple line diverges upward, it shows that the upward trend has not changed. The previous stock price decline is only a callback on the way, which can be followed up appropriately. 4, the main force in and out of the third line "death cross", the handicap is empty, investors should be out as soon as possible. 5. When the main force enters and exits the third line and goes down in parallel, it means that the main force has not entered the market or is shipping, so it is not appropriate to intervene at this time. 6. The main force in and out is a trend indicator, but the trend change signal sometimes lags behind. At this time, it is necessary to use the main trading indicators to cooperate.
