How to achieve low suction practical skills

Selling high and buying low is an effective strategy for stock investment, and it has almost become the motto for investors to trade stocks, but there are few successful ones. Why is that so? Is the difficulty of the operation technique too high? Not really. But it is a weakness of human nature - caused by greed. When the stock price in your hands skyrockets, the desire to conquer will change the direction of your thinking and become an infinitely inflated desire for profit. After a wave of gains, you still hold onto the stock and look forward to the second and third waves. Rising one limit up, waiting for the second and third limit up. When the stock price rises and falls, staring at the gradually decreasing price, even when the stock returns to the starting point, the desire to get the highest price has been frozen in one's heart, unwilling to reduce profits or stop loss and lose the opportunity to profit.  
Generally speaking, the safety factor of low-level fundraising is higher, and the probability of profit is greater. However, waiting for the best opportunity to attract requires patience and endurance. At this time, one should firmly believe in oneself. No matter how long the night is, it will always be replaced by a brilliant dawn, and no matter how painful the suffering is, there will always be an end. However, what stage and time are the best opportunities for low suction?
The following examples are provided for investors' reference:
1、 Stocks that are trading sideways at the bottom and are not affected by the rise or fall of the market are safe to buy at any time, especially when the last bearish candlestick or the start of an upward breakout is the best opportunity to buy low with huge profit margins. Many dark horse stocks in the stock market have experienced such a trend.
2、 The K-line chart has been bearish for a long time, the stock price has fallen several steps, has not stopped falling below all moving averages, the daily trading volume has gradually shrunk, the K value is negative, the J value has been inactive for several days at negative values of 10-20, the divergence rate has been inactive above 1 to 10, and the strength indicator has been inactive below 10. If stocks with one of the above characteristics appear, they will have a certain degree of increase. Stocks with all of the above characteristics will have a huge increase, and profits will not only be reliable but also considerable.
3、 Stocks that run at the bottom of the price box and do not have significant new low technical indicators can be boldly absorbed, and investing in such stocks can yield stable returns.
4、 The market has been stimulated by negative news and has been plummeting for days, with individual stock prices falling to historical lows, mostly by more than 10%. At this time, absorbing any stock can yield unexpected returns.
High throwing and low sucking require decisive and quick entry and exit, a slight hesitation will result in losing the best opportunity. Opportunities are flashes in the flow of time, and it is difficult to obtain similar opportunities after losing them. The opportunities in the stock market are fleeting.
Seizing opportunities and utilizing time differences to make profits is the focus, focal point, and core of stock trading. Profit and loss are determined at this critical moment
