In the stock time-sharing chart, the white line represents the time-sharing price line of the stock, and the yellow line represents the moving average of the price. Generally speaking, the white line of small and medium-sized stocks fluctuates greatly, which will form multiple high and low waves. If it is low/high, the second lowest point is the buying time; if it is low/high, the second highest point is the selling time. & ltbr/>； The above is the general situation, and it is not guaranteed to buy the lowest and sell the highest, but it is profitable and has little risk. Sometimes there is no obvious trend on the time-sharing chart. In this case, it is best not to participate, because there is a great possibility of misjudgment.
