In a long trading career, among millions of trades, any single transaction is just a drop in the ocean. Many people understand this principle, but truly practicing it is very difficult.

When you make a profit, you tend to get carried away; when you suffer a loss, you feel regret. Success makes you proud, failure leads to self-doubt. These emotional fluctuations seem normal, but in reality, they are the most dangerous signals in a trading career. When you find yourself becoming impatient, blind, fearful, or anxious due to market fluctuations and asset changes, regardless of whether your account is in profit or loss, you have already lost psychologically.

The market is like a magnifying glass; it amplifies every trader’s emotions infinitely. Your greed, fear, and luck-driven psychology are all pushed up and down by the market waves, eventually exhausting you. When you are exhausted to the limit, the market often delivers the most deadly blow at this moment.

This is why a calm mind is the most core competitive advantage of a professional trader. Not because it is high-end, but because it is rare.
