#风险回报比 Risk/Reward Ratio (R/R) is one of the core reference indicators for my trading strategy. The calculation method is: expected profit / expected loss. For example, if the target profit is $300 and the stop loss is $100, then the R/R is 3:1. In real trading, I only choose opportunities with an R/R greater than 2, and evaluate the expected value of the strategy (profit/loss ratio × win rate - loss ratio × failure rate) in conjunction with the win rate. I use the TradingView backtesting tool combined with indicators such as ATR, moving averages, and Bollinger Bands to set reasonable entry and exit points. The risk/reward ratio helps me filter better trading opportunities in a choppy market, reduce frequent trading, and improve overall returns and capital efficiency.
