For general stocks, you can look at the trading volume. When a stock rises, it must be coordinated with the volume. As the stock price rises, the volume will also increase or maintain. If the stock price rises for a period and suddenly releases a large amount, then the trading volume shrinks rapidly, it will indicate a turning trend. The extremes of things must reverse from strong to weak, and from weak to strong. When will the kinetic energy exhaust? First, look at whether a large amount is released in a single day or several consecutive days, and see whether the MACD red column shortens. At a high level, see whether the stock price is weak in rising. If the stock price is sluggish at a high level, it indicates that the strength of many parties has weakened. Generally, stocks will have selling opportunities for a few days when they are at a high level. It is difficult to judge the decline. You don't need to coordinate the decline with volume, and the stock price can drop infinitely. If you can't judge the bottom, you can wait for the market to come out on its own before participating. The top will be short, and the bottom will be long.
