#风险回报比 I adhere to the 1:3 principle: potential profit must be at least three times the risk. For example, buying ETH with a 5% stop loss and a 15% take profit target. Using the ATR indicator to measure volatility, combined with support and resistance levels to calculate the ratio. Strict execution allows me to be profitable even with a win rate of only 40%. How do you calculate the risk-reward ratio? Chart tools or fixed ratios?
