Direct answer
In forex, a risk reward target matters because it turns a general idea of “limiting loss and aiming for a gain” into a measurable relationship between the distance to your stop level and the distance to your take-profit level. That relationship helps you compare plans consistently and evaluate whether a setup is coherent under the rules you chose.
However, it is not a prediction and it does not remove uncertainty. Real outcomes depend on how price moves (including whether it reaches the target or stop first), transaction costs, execution quality, and the measurement conventions used.
Mechanism and definition
A “risk reward target” is typically expressed as a ratio:
- Risk (R): the planned loss distance from an entry to a stop level.
- Reward (T): the planned gain distance from an entry to a take-profit level.
- Risk reward ratio ≈ T ÷ R, as long as both distances use the same units and measurement method.
In practical terms, you choose levels (entry, stop, target). Then you compute the ratio and use it to understand the plan’s shape:
- If the target is farther than the stop, the ratio is larger.
- If the stop is farther than the target, the ratio is smaller.
A material point is that the ratio alone does not define the dollar amount at risk or the dollar amount of potential gain. To translate distances into monetary effects, you must apply additional assumptions such as position size and how pip/point value maps to your instrument.
Evidence or example (scenario-impact-4)
Assume a hypothetical plan with these fixed distances (no live prices):
- Entry at the current price.
- Stop is 20 pips away.
- Target is 50 pips away. Then the risk reward ratio is 50 ÷ 20 = 2.5.
Now consider two realistic scenario impacts:
- Price path uncertainty: Even if the ratio is 2.5, price can reach the stop before the target, or never reach the target.
- Cost and execution effects: Spreads, commissions, slippage, and order type can change the effective entry/exit points, meaning the “planned” R and T distances used in the ratio may not match “achieved” results.
This is why the target matters: it is a consistency tool for your planning, not a guarantee about which outcome occurs.
Limitations and risks (material failure modes)
At least one common limitation is measurement mismatch. Many traders compute risk reward from the intended levels, but real fills can differ. If your stop or target is triggered using broker execution rules, the realized distance can change.
Other material risks:
- Model oversimplification: A ratio summarizes distance but ignores how price behaves between levels.
- Cost sensitivity: When trading frequency increases or costs are larger, net outcome may diverge from the geometric ratio.
- Assumption dependence: If pip value, position size, or contract specifications differ from what you assumed, the monetary meaning of “risk” and “reward” changes.
Because historical relationships do not establish future results, a plan with a certain ratio may perform differently across market regimes.
Verification and next question
You can independently verify a risk reward target by checking the exact inputs used for R and T:
- Confirm your stop and target distances were measured from the same reference point (for example, your actual intended entry).
- Recalculate the ratio using T ÷ R with those distances.
- If you want to validate monetary risk/reward, also confirm the position sizing and pip/point value assumptions.
A useful next question is: “When the order is executed, do the actual fills produce the same effective distances you used in the calculation?” That question directly targets the biggest practical failure mode: planned numbers that do not match execution reality.
