1. Only select stocks whose main trend is upward and in the upward channel to operate, and never pay attention to stocks whose important trend is obviously in the downward channel to take risks. When buying, it's best to intervene at the first time when the main upward trend is improving and the inflection point of the middle upward trend just appears, sell at the first time when the main trend is blocked and fall back, and intervene at the first time when the stock is sideways for a long time.

2. The market is the weather vane of individual stocks, so you must pay attention to the face of the market when buying and selling.

3. Only buy and hold stocks whose stock price has doubled in a short time just after the bottom has started or just left the bottom area. In principle, it is best not to participate, and never to participate in all kinds of uncertain adjustments that have just begun.
