For those who enter the downward trend from the upward trend, you can pay attention to the operation of K-line. In a certain level of trends, except for a few V-shaped reversals, many trends have to be transformed through the game of long and short forces, with a top shape above the trend or a new high of failure. If k continues to fall and breaks through the support of the previous low point, then the probability of downward will increase.
Or use the moving average system, when K falls to an important moving average, the moving average successfully suppresses the K line below, or causes a dead fork of the moving average, which can be used as a judgment of falling. However, the trend of futures is uncertain, which does not mean that it will definitely go downhill. Sometimes it may just be an illusion, and sometimes it just goes into shock.
For those who enter the shock, the amplitude of some shocks is erratic, and some will fluctuate within a regular range. For the shock of the rules, you can wait for its breakthrough direction and then follow up. For example, the K-line effectively fell below the support of the shock. The probability of going down at this time will be even greater. Stop loss follow-up can be set.
