There are three methods:

One is fixed investment, you can use smart fixed investment, and let the system select the fixed investment amount according to the rise and fall;

The other is to choose one yourself Buy the part at a relatively low point (that is, there have been several consecutive declines);

The third option is to continue to wait for the low point. If it continues to rise and the upward trend is strong, then you should consider reducing your position at the high point and take some of the money first. . Wait until the price drops too much before buying.

The law of the stock market: If it falls for a long time, it will rise; if it rises for a long time, it will fall!
