It definitely makes sense. K-line form can best explain the current long and short power. Take the nearest market as an example. On the fourth day, it rebounded for three consecutive days, with a super big yinxian line, one yin eating three yang, and 99.99% predicted that the short-term market would fall. Basically, as long as you know a little, you will lighten up your position. If you don't lighten your position, the bank's support index will not fall much, but basically, it is very easy for individual stocks to fall by 20%.
