Generally, we can judge the first step according to the operation law of the K-line chart on the disk. Open your disk and adjust the cycle to the monthly and weekly lines. If the K-line obviously shows a gradual downward trend and the low point is constantly refreshed, it means that it is a weak trend at present, and vice versa. When we have determined the general direction of the big cycle, let's take a look at the operation of the bollinger bands on the monthly and weekly lines. If the K-line falls with the lower rail of the Bollinger Band for a long time in the falling market, it means that the current falling stage is still accelerating, so it can rebound and short. In the downward trend, if the price falls out of the lower rail, the middle rail shows signs of rebound, indicating that the previous decline has ended, and the empty orders should be profitable as soon as possible in the short term.

Slightly different from the big cycle, the silver price on the daily chart will stick to the middle rail of the bollinger Band more often, but it is obviously in a volatile trend at this time. Short-term trading can choose the bollinger Band to overestimate and low slag. At the same time, it can be operated according to the moving average system. When the short-term moving average is golden, do more near the moving average and see the Brin pressure.
