Risk-reward ratio in trading
How to calculate risk-reward ratio from entry, stop, and target—and why R:R pairs with invalidation and win rate before you take a setup.
The risk-reward ratio (R:R or reward-to-risk) compares potential profit on a trade to potential loss—usually measured from entry to target (reward) versus entry to stop (risk). It is a core discipline tool for deciding whether a setup is worth taking before you enter.
ChartGuru derives risk/reward from suggested entry, stop (invalidation), and target levels on technical analysis—and emphasizes invalidation on every scored read.
How to calculate risk-reward ratio
Formula: Reward ÷ Risk
| Input | Definition |
|---|---|
| Entry | Your planned entry price |
| Stop / invalidation | Price where the thesis fails |
| Target | Planned take-profit or structural objective |
| Risk | |
| Reward |
Example: Entry $100, stop $95 (risk $5), target $115 (reward $15) → R:R = 3:1.
Why risk-reward matters
- Filters bad setups—low R:R trades need very high win rates to survive costs and variance
- Pairs with win rate—a 1:1 R:R strategy needs >50% wins before costs; 2:1 needs lower win rates
- Forces planning—you define invalidation before hope sets in. See invalidation points
ChartGuru landing and Guru outputs emphasize invalidation and key levels even when a numeric R:R is not displayed—you stay responsible for sizing.
Common mistakes
| Mistake | Fix |
|---|---|
| Measuring R:R without a real stop | Use invalidation, not arbitrary percentages |
| Targeting unrealistic extensions | Anchor targets to structure, not fantasy numbers |
| Ignoring win rate | High R:R with rare wins can still lose over time |
| Moving stops after entry | Honor invalidation; see confidence scores to compare setups, not to avoid stops |
Risk-reward by asset class
Stocks
Gap risk can skip stops—define pre-market vs RTH stop rules.
Crypto
Use zone-based stops; wicks overshoot lines. Wider invalidation → smaller size for same dollar risk.
Forex
Pip-based R:R on majors; watch spread and session volatility around news.
Gold
Macro events (CPI, FOMC) can blow through tight stops—widen invalidation or stand aside.
FAQ
What is a good risk-reward ratio?
There is no universal number—2:1 or 3:1 is a common minimum filter for discretionary traders, but win rate and execution quality matter as much as the ratio.
How is risk/reward calculated on ChartGuru?
On Technical Analysis, ChartGuru derives R:R from entry, stop (invalidation), and target: reward is distance to target, risk is distance to stop, R:R is reward divided by risk.
Is high risk-reward enough to take a trade?
No. You still need edge, confluence, and acceptable probability. See confluence in trading.
Does ChartGuru tell me position size?
No. ChartGuru is analysis-only—you size positions and set stops; confidence helps compare setups, not replace risk management.
What's the difference between R:R and invalidation?
Invalidation is where the thesis breaks; R:R compares that risk to potential reward. Invalidation is the logic; R:R is the math.
