Mental performance in trading refers to a trader's ability to maintain focus, discipline, and emotional stability under the pressure of fast-moving markets. High mental performance allows traders to make clear, rational decisions even during periods of volatility or after experiencing losses. It involves managing stress, staying resilient, and maintaining confidence without becoming impulsive or overconfident. Factors such as sleep, physical health, mindfulness, and routine all play a role in supporting mental sharpness. Consistently strong mental performance helps traders execute their strategies effectively, avoid emotional mistakes, and adapt to changing conditions with clarity and control.
