#风险回报比 1. For funds within 100,000, buy only one currency; for 200,000 to 300,000, buy two; for under 500,000, buy 3-4. Even if the funds are more, do not hold more than 5 positions. Concentrate funds in a bull market, and hold a small amount during poor market conditions to be able to stop losses in time.

2. The only purpose of watching news and learning techniques is to improve the win rate. Trends determine everything: rebounds in a downtrend are often traps to entice buyers, while declines in an uptrend are often for digging pits. Do not fantasize about bottom fishing, nor speculate on the main force's direction.

3. Only operate when the market is active, and maintain flexibility in response.
