When the K-line goes up, the screen lights up. Staring at it for too long starts to cause soreness, blurriness, and distraction. It used to be manageable, but now I realize that my body is giving me stop-loss signals before the market does. Someone joked that with myopia, I should get lens implants, or it could affect my crypto trading. It sounds funny, but it's actually quite true. This market tests not only your cognition and emotions but also your hardware conditions, which are draining you. If your eyes are not good, your judgment becomes slow; if your condition is poor, your operations tend to distort. In the end, I realize that the body is the earliest to be neglected but the most important position.
