Earlier, it opened above 2178, reached 2260 but didn't exit, then washed out at 2180, and later opened a position at 2193. The lowest dropped to around 2150, which was quite scary, but fortunately held on. Unfortunately, half was cut at 2253, and another half at 2370. I initially thought about reaching 3000 points, but I still didn't achieve unity of knowledge and action. I was still shaken out by the volatility.
