#风险回报比 1. Dynamic Adjustment of Stop Loss and Take Profit

• Volatility Adaptation: High volatility assets (such as altcoins) require a wider stop loss distance to avoid frequent stop outs.

Example: ETH daily volatility 5%, stop loss can be set at 2%-3%.

• Technical Pattern Combination: Set stop losses near support/resistance levels, for example, exit when breaking below the Fibonacci 61.8% retracement level.

2. Trade-Off Between Win Rate and Ratio

• Break-Even Formula: Break-even win rate = 1/(Risk-Reward Ratio + 1)

◦ A 3:1 ratio requires ≥25% win rate

◦ A 5:1 ratio requires ≥16.7% win rate.

• Practical Suggestions: Preferably choose a 1:2 or 1:3 ratio to balance returns and feasibility.
