Since it is a long line, it is necessary to judge the trend, only look at the weekly and daily lines, not the cycle below the daily line! Follow the 5 10 20-day moving average to go long or short, try to open a position with small funds, and set a stop loss. The market goes up or down on the 5th, as long as it doesn't fall below or break through, it can always be held, and the floating surplus can be appropriately added. In principle, don't break through the 30% position. There is an intersection between day 5 and 10. As long as you don't fall below or break through the 20th day, you can still hold your position safely. If the position is too heavy, you can reduce the position appropriately. The elbow of the 20-day moving average turns down or up, which can basically clear the position. Eating fish in the middle is not recommended. This is only a simple analysis at the technical level, and it really needs to be combined with the fundamental analysis of different futures varieties.
