The risk-reward ratio (R/R ratio) of #风险回报比 is a core indicator for evaluating 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, one can still achieve long-term profits. Blindly chasing after prices while buying high and selling low often neglects risk control, while setting clear stop-loss and target levels is a reflection of rational trading. High-reward opportunities are often accompanied by high risks; the key is whether it is worth taking that risk. Mastering the risk-reward ratio is the first step towards stable profitability and an important cornerstone for establishing a trading system.
