#风险回报比 The risk-reward ratio (R/R ratio) is a core indicator for assessing the value of each trade. A good risk-reward ratio, such as 1:2 or 1:3, means that even with a low win rate, long-term profit can still be achieved. Blindly chasing after price increases and decreases often ignores risk control, while setting clear stop losses and target levels is a reflection of rational trading. High-reward opportunities often come with high risks, and the key is whether it is worth taking that risk. Mastering the risk-reward ratio is the first step towards stable profit and an important foundation for building a trading system.
