The risk-to-reward ratio (R:R) answers the core question in trading: is the potential profit worth the risk I’m taking? This metric determines whether a trade makes sense by showing where you’ll exit at your stop loss, where you’ll take profit, and how often you need to be right for your strategy to be profitable. Using this ratio enforces discipline, eliminates impulsive entries, and builds a system that survives losing streaks.
Understanding Risk and Reward
The risk-to-reward ratio uses a simple formula:
Risk-to-Reward Ratio = Potential Profit ÷ Potential Loss
- Risk (R) — the predetermined loss in dollars or pips when your stop loss is triggered.
- Reward — the calculated potential profit when your target price is reached.
Common examples:
- 1:1 — risk 100 pips to gain 100 pips profit.
- 1:2 — risk 100 pips to gain 200 pips profit.
- 1:3 — risk 100 pips to gain 300 pips profit.
Your stop and target must be based on market structure, not forced to fit a round number.
Why Win Rate Alone Doesn’t Matter
Consider two traders: Trader 1 wins 75% of trades, while Trader 2 wins only 40%. Which is more successful? You cannot answer without knowing how much each trader makes on winning trades and loses on losing trades. Win rate is not the most important factor in trading success. The risk-to-reward ratio is what separates profitable traders from those who break even or lose money despite high win rates.
How to Calculate Before Every Entry
The calculation takes under a minute and must be done before every single trade:
- Identify your stop level on the chart (typically below a key support level).
- Subtract the stop price from your entry price — this is your risk per share.
- Identify your first realistic target (prior day high, gap fill level, or measured move extension).
- Subtract your entry price from the target — this is your reward per share.
- Divide reward by risk.
- If the ratio is below 2:1, pass on the trade. This is a hard rule, not a guideline.
Practical Example: The 1:2 Ratio
The 1:2 ratio is one of the most effective setups. If you open a trade risking 25 pips, set your take-profit at 50 pips.
Here’s how to manage it:
- You buy at 1.2500 and set your stop loss at 1.2475 (25 pips risk).
- Set your take-profit at 1.2550 (50 pips profit).
- When price reaches 1.2525 (halfway to your target), move your stop loss to 1.2500 (your entry price).
- Now you either lock in profit or break even — you cannot lose.
- Once your stop is at breakeven, you can look for additional entry points with the remaining position or close it entirely.
This approach protects your capital while keeping upside potential intact.
Position Sizing and Risk Percentage
Risk percentage determines how much of your account you risk on each trade. If you have a $10,000 account and are willing to lose $500 per trade, your risk percentage is 5%. This means each position should not exceed $500. Your account size directly determines how much capital you allocate to each trade, which then influences your position size based on your stop distance.
FAQ
What is a good risk-to-reward ratio in trading?
Many traders aim for at least 1:2, but the right ratio depends on your strategy, win rate, and the structure of the setup.
Can you be profitable with a low win rate?
Yes. If your average winning trade is much larger than your average losing trade, you can still be profitable with a modest win rate.
Should I force every trade into a 1:2 ratio?
No. The stop loss and target should come from the chart and market structure first, then you evaluate whether the ratio is acceptable.
