Summary:

From February to early April, there was a unilateral decline, and I specifically took short positions on rallies, which went very smoothly.
On April 12, both 74666 and 76666 showed signs of bottoming out, but due to frequent changes in tariff information, it was hard to hold long positions. Initially, it was just a rebound, and it oscillated around 86000 for about 11 days. When it strongly broke through 86000, it became very certain that the bearish trend had reversed into a bullish one, so on April 24, it was anticipated to reach around 105000, and it was said it would get there within 3 weeks. However, out of habit, the short positions in between were often not monitored for profit-taking or stop-loss, which resulted in a significant loss of profits on long positions. Therefore, to summarize, once the reversal of a bearish trend is confirmed or anticipated, one can only take one direction, which is to buy on dips. Just like when it fell below 92000 in February, I said the bullish momentum was gone, and it turned into a one-sided decline, focusing only on short positions, which resulted in almost no losses. From this perspective, shorting can be quite addictive.
Many people believe that it has already risen significantly and are hesitant to go long. This is a cognitive error; it is precisely because it has broken through key resistance that one should go long. Follow the trend; when it's time to go long, just do it without regrets. The higher it rises, the more one can try shorting with a light position in the high sell zone (such as 107125, 110000) to nurture the position, and take profit when it peaks and pulls back.
