#交易心理学 The study of trading psychology examines the impact of emotions and cognition on investment decisions. The core issue is overcoming human weaknesses—fear induces irrational selling, greed leads to excessive risk-taking, and herd mentality triggers collective misjudgment. Traders must constrain instinctive reactions through strict discipline, establish verifiable trading systems, employ stop-loss rules to manage risk, and regularly review decision-making biases. It is crucial to distinguish between market fluctuations and cognitive biases, avoiding loss aversion and confirmation bias that interfere with judgment. Long-term profitability depends on emotional stability and depth of self-awareness.
