1. Reversing to find profit points refers to the reversal of futures prices. The inverted price height is usually the space size of the future band of futures prices. Speculators can predict the position of price rise or fall in advance according to the height of reversal when judging profit expectations. 2. It is an effective method to find profit points at support level and pressure level, because under normal circumstances, the fluctuation trend of futures prices will not easily turn. Once there is a reversal signal, the corresponding price must be an important support level or pressure level. And such a price can be regarded as the target price of investors. When the futures price fluctuates to this resistance position, the speculators' profit target is reached. 3. Look for profit points in the cycle. Looking for potential profit points from the futures price cycle, if the period used by investors is good and the starting point and ending point are properly selected, the desired reversal point can be better predicted, and better profit points can appear on the nodes of the effective cycle.
