Let’s review. Last night, I saw a one-hour effective rebound and the MACD showed a bullish crossover, so I changed my previous bearish view and, with a probing mindset, decided to be a bit aggressive and make a short-term trade. In the end, the rebound effectively broke above 4350 and fluctuated around 4370 several times. From this, I judged that it was a tug-of-war to increase liquidity. Although I thought about making a short-term trade within this range, I ultimately gave up considering how difficult it would be to grasp. After setting a stop-loss, I took a break. In the morning, the price remained below 4300 and I couldn't see any effective rebound. It eventually broke below the stop-loss level of 4240, and I initially planned to stop loss. I was also worried about the support level at 4200 being only 40 points away; if it rebounded after I stopped loss, I wouldn’t have an effective strategy to defend. Ultimately, it not only broke 4200 but also fell below that level. Therefore, I added a position at 4192, as this level was only 30 points away from the strong support at 4160. Even if it reached the stop-loss level, I could accept the profit drawdown, and I prepared a final defensive strategy (below 4160) and executed it resolutely. Currently, I have observed an effective rebound on the left, but I still need to review. When the profit margin is low and the position is not good, even if I judge that there is an opportunity, I should not blindly make trades, as a small margin for error can lead to an imbalanced mindset and continuous mistakes.
