About Risk/Reward Ratios

The risk/reward ratio is a fundamental concept in trading that compares the potential loss (risk) to the potential gain (reward) of a trade. It helps traders evaluate whether a trade is worth taking and is a key component of risk management.

Interpreting the Ratio

A risk/reward ratio of 1:2 means you're risking $1 to potentially gain $2. Lower ratios (like 1:3 or 1:5) are generally more favorable as they indicate a greater potential reward relative to the risk.

倉位管理

Proper position sizing ensures you're risking an appropriate amount of your trading capital. The recommended approach is to risk a small percentage (1-2%) of your account on any single trade.

Break-Even Win Rate

This is the minimum winning percentage needed to break even over time. With a 1:2 risk/reward ratio, you only need to be right on 33.3% of your trades to break even.

Expectancy

Expectancy combines win rate with risk/reward to determine the expected return per dollar risked. Positive expectancy is essential for long-term profitability.

Tips for Using Risk/Reward Effectively

  • Aim for a risk/reward ratio of at least 1:2 to maintain profitability even with a win rate below 50%.
  • Always define your stop loss and take profit levels before entering a trade.
  • Consider adjusting your position size to keep risk consistent across different trades.
  • Track your actual results to determine your empirical win rate and adjust your strategy accordingly.
  • Remember that a favorable risk/reward ratio doesn't guarantee success; market analysis is still crucial.

本工具計算什麼

潛在回報與所承受風險的比例。

公式
風險回報比 =（目標價 − 入市價）÷（入市價 − 止蝕價）
計算示例
入市 1.0850、止蝕 1.0800、目標 1.0975。風險 50 點、回報 125 點，比率為 2.5:1。
何時使用
入市前評估，判斷該筆交易是否值得進行。
常見錯誤
比率高不代表交易好。5:1 的機會若勝率只有 10%，長遠仍會虧損。
