The SOL market has been fluctuating throughout the weekend, and I didn't dare to hold a heavy position. I opened a long position of 10 contracts at the 0.42 level, feeling a lot of psychological pressure—then suddenly it dropped to 0.13, and I didn't even have the courage to add more. Fortunately, after holding for a while, the minute chart started to show signs of recovery, so I waited. In the end, I sold at the 0.82 level. The principal was 4.2u, and when I exited, it became 8.2u, netting a profit of 4u. Honestly, I didn't dare to wait for the market to finish, as today's choppy market is hard to predict, so I was satisfied with taking some gains along the way. This round was quite lucky; the key is that I didn't be greedy and took profits in time.
