Yesterday I lost again. To put it simply, it's still caused by lack of sleep. When in a bad state, the originally clear trading logic becomes blurry, hesitant to cut losses on certain orders, and stubbornly chasing the market when it should be observed. In the end, it results in a series of reckless operations, and the account suffers. It seems that without sufficient rest, discussing any trading strategy is just nonsense. I need to reflect properly and make sure to get enough sleep before trading.
