A true trader should remember these four points:

1. Don't be greedy or panicked; decisively exit when you incur losses, and diligently safeguard every hard-earned dollar.

2. If you don't understand something, don't force yourself to enter the market. Trade less, stay calm, avoid fighting the market, and don't make things difficult for yourself.

3. Keep a small position, follow the trend, stay disciplined, and proceed steadily. Take your time to go further and feel more secure.

4. Maintain a stable mindset, and profits will come as expected. Trading is a form of cultivation; keep your mind steady to protect your wealth.
