**Why is trading a practice? **

1. **Complexity of the market**: Facing the complexity and volatility of the market, the key to trading is to simplify and find a way out of uncertainty.

2. **Practice in actual combat**: The true knowledge of trading can only be obtained in real trading. Only by experiencing counter-trend trading, holding orders, liquidation and doubling, can we truly understand the market.

3. **Multiple challenges**: Traders need to overcome multiple levels such as technology, system, fund management, emotions, psychology and unity of knowledge and action. Without self-improvement, these obstacles cannot be broken.

4. **The way of giving up**: It is impossible to seize all opportunities in trading. You must learn to make choices and focus on the areas you are familiar with, so as to achieve "three thousand weak waters, only take one scoop".

5. **Consistency of execution**: It is extremely difficult to maintain the consistency of trading strategy execution, which is easily disturbed by the fluke mentality and requires strong inner determination.

Trading behavior reflects the inner world of traders. From greed, fear to obsession and regret, various mentalities are reflected through the appearance of trading. Only through introspection and self-cultivation can traders find their true selves and continue to grow in trading.
