Always stay vigilant when trading, never have a mindset of luck. Today, the SUI short position was originally profitable by about $60. Clearly, I saw the four-hour bottom divergence, and I knew that after the big coin broke the new low a few days ago, it would rebound. However, during the rebound process, there were always profit opportunities that I didn't take. Now I have endured until now and lost over $100, considering the original profit, today I lost two positions of over $100. Learn the lesson!
