In the investment market, the first thing to understand is: the market is always right. The market doesn't make mistakes; the real issues often stem from human cognition and emotions. Many people focus all their energy on technical analysis, but in reality, if a person's mindset is unstable, even the best technical skills are meaningless. Once emotions spiral out of control, the system deforms, execution goes awry, and ultimately, technical skills become zero. This is the most core aspect of trading. All the ups and downs and fluctuations seen in the market are essentially just “appearances.” If you cling to these superficial phenomena, it's easy to be led astray: first greed, wanting to earn more; then delusions, having unrealistic expectations about the market; followed by biased judgments, intensified emotions, and finally, obsession that causes one to lose objectivity. The true practice of trading is not to conquer the market but to correct oneself. Reduce attachment, minimize emotional interference, and prevent oneself from being driven by short-term fluctuations. In the end, those who can maintain long-term stability rely not on predictions but on a calm, unwavering mind. When the mind is steady, trading is steady. This is the “Dao” in trading.
