Most of the time, stocks are rational and regular. Although each stock has a different personality, they are all the same. You need to keep researching and observing, and until your experience is accumulated to a certain point, you will know how to follow the trend. Wait, be patient, observe, and only enter the market if the stock's movements meet your entry requirements. Only then can you be sure that your chance of winning if you enter the game is greater than 50%. On this basis, continuous profit is possible. Of course, don't forget to protect your capital.
