1. Use affordable money for investment, especially when the trading system is not yet mature. 2. Do not use high leverage, the maximum is no more than 10 times. 3. Open a position with a stop loss, unless it is spot, but I think it is better to sell when the spot price falls below the psychological price, and then it is safer to enter again when the opportunity arises. 4. Light position on the left, and increase the position on the right. 5. Always think that you may make mistakes and constantly improve the safety margin. 6. Do not do overnight orders, unless it is spot. Poor sleep will affect your life and trading judgment. These points are very simple, it seems that everyone knows them, but in fact, I have learned them by spending money and time. How many people here are repeating mistakes? If you don’t correct your mistakes, you can only keep paying tuition. This is the cruelty of the market itself. I can only say this. Encourage each other.
