In fact, Yi Lihua's first operation can be described as perfect. The first buy was on the right side, and then he held the position steadily until exiting near the last high point of $4110, which is completely reasonable; the second buying operation was also fine, buying again in the last rising consolidation area, which is probably the cost area of many buying chips. This is very normal and has no issues; however, the biggest problem was not withdrawing in time after the trend turned bad. No one can always make the right judgment; the biggest obstacle for most people is to correct their views in time and withdraw promptly when they are wrong.
