Risk/reward is a planning ratio, not a guarantee.
A risk/reward ratio compares potential loss to potential gain before a trade is entered. For example, risking 100 to target 200 is commonly described as 1:2 risk/reward.
The ratio does not say whether the trade is good. It must be combined with probability, spread, slippage, position size, order type, market conditions, and the trader's ability to follow the plan.
How the ratio is calculated
The basic calculation starts with three prices: entry, stop-loss, and target. The planned risk is the distance from entry to stop. The planned reward is the distance from entry to target. The ratio compares those two distances.
| Example | Entry | Stop | Target | Risk | Reward | Ratio |
|---|---|---|---|---|---|---|
| Long trade | 100 | 95 | 110 | 5 | 10 | 1:2 |
| Short trade | 100 | 104 | 92 | 4 | 8 | 1:2 |
| Weak setup | 100 | 98 | 103 | 2 | 3 | 1:1.5 |
For forex, futures, and CFDs, the same idea applies but the distance must be converted into money using pip value, tick value, contract size, or position size.
A high ratio does not automatically make a trade better.
A 1:5 target can look attractive, but if the target is unrealistic or rarely reached, the setup may still be poor. A 1:1.5 trade may be reasonable if the process has strong evidence and disciplined execution. Beginners should avoid judging a trade only by the size of the target.
The better question is whether the stop and target are located for logical market reasons. If the stop is too tight, normal noise may remove the trade. If the target is too far, the trade may rarely complete.
Break-even win rate
The ratio can help estimate the minimum win rate needed before costs. This is only a simplified planning concept, not a forecast.
| Risk/reward | Simple break-even win rate before costs | Beginner caution |
|---|---|---|
| 1:1 | About 50% | Costs and mistakes push the real requirement higher |
| 1:1.5 | About 40% | Still needs realistic targets and consistent execution |
| 1:2 | About 33% | A few large losses can still damage results |
| 1:3 | About 25% | Targets may be harder to reach consistently |
Transaction costs, spreads, commissions, slippage, missed trades, early exits, and emotional rule-breaking can all change the real break-even level.
What can distort the ratio
Spread
The distance between bid and ask can reduce the practical reward or increase effective entry cost.
Slippage
Fast markets can execute stop or entry orders at a worse price than expected.
Partial exits
Scaling out changes the average reward and should be planned before entry.
Moving the stop
Expanding risk after entry can destroy the original ratio and risk plan.
Unrealistic targets
A far target that price rarely reaches may only make the plan look good on paper.
Step-by-step workflow
- Define the trade idea before entering.
- Choose the invalidation level first, not the profit target.
- Measure the distance from entry to stop.
- Choose a realistic target based on structure, volatility, or planned exit logic.
- Convert the distance into money risk using position size.
- Include spread, commission, and slippage assumptions.
- Decide before entry whether partial exits or trailing stops are part of the plan.
- Record the planned ratio and actual exit result in a journal.
Risk/reward and position sizing work together
Risk/reward describes the shape of the trade. Position sizing describes the money at risk. A trade with an attractive ratio can still be dangerous if position size is too large. A beginner should usually decide account risk first, then calculate position size, then verify whether the stop and target still make sense.
| Decision | Question | Tool |
|---|---|---|
| Account risk | How much money can this trade lose? | Risk percent or fixed currency amount |
| Stop distance | Where is the idea invalidated? | Chart structure or volatility reference |
| Position size | What size matches the planned loss? | Position size calculator |
| Target | Where is reward realistic? | Support/resistance, range, trend, or planned exit method |

FAQ
Is 1:2 risk/reward always good?
No. The target still needs to be realistic, and the trade needs a process with enough probability after costs.
Can risk/reward be used for investing?
Yes, but long-term investing usually uses broader risk, valuation, time horizon, and portfolio allocation concepts rather than a single stop-and-target calculation.
Should beginners chase high reward ratios?
No. Very high targets can encourage unrealistic plans. Start with disciplined risk control and realistic exits.
