Risk Reward Ratio: meaning for forex traders explained
By Ken Chigbo, Founder, KenMacro. Published 2026-05-13.
Quick answer
The risk reward ratio measures a trade’s potential reward divided by its potential risk, where risk is the distance from entry to stop and reward is the distance from entry to target. A 1:3 ratio means the trader is risking one unit to make three. It is a core filter for setup quality and long-run profitability.
What is risk reward ratio?
Risk reward ratio is a simple arithmetic measure used to evaluate a trade before execution. It is calculated by dividing the planned profit distance, from entry price to target, by the planned loss distance, from entry price to protective stop. A ratio expressed as 1:2 indicates that the trader stands to gain two units of price for every one unit risked. The metric is independent of position size and currency, which makes it directly comparable across markets, timeframes, and instruments. It is one of the foundational risk management inputs alongside position sizing and win rate.
How traders use risk reward ratio
The desk applies the risk reward ratio as a pre-trade filter rather than a post-trade scorecard. A setup is mapped using structural levels: the stop sits beyond an invalidation point such as a swing high, a session low, or a volatility band, while the target sits at a credible liquidity pocket or measured move. The ratio then falls out mechanically. Retail traders typically demand a minimum of 1:2 to compensate for variable execution and slippage, while institutional desks may accept lower ratios on mean-reversion strategies where hit rates are structurally higher. The metric pairs with win rate to define expectancy: at a 40 percent win rate, a 1:2 ratio produces positive expectancy, while a 1:1 ratio does not.

Worked example of a risk reward ratio
Consider a EUR/USD setup where price is trading at 1.0850. The trader identifies structural invalidation at 1.0820, twenty pips below entry plus a ten pip buffer, placing the stop at 1.0820. The next significant liquidity level sits at 1.0940. The risk distance is 30 pips, the reward distance is 90 pips, and the resulting ratio is 1:3. If position size is set so that the 30 pip stop equals one percent of account equity, a winning outcome returns three percent. The ratio holds regardless of whether the account is one thousand or one million units.

Frequently asked
What is a good risk reward ratio for forex trading?
There is no universal answer because the appropriate ratio depends on the strategy’s win rate. A trend-following approach with a 30 to 40 percent win rate generally requires a minimum of 1:2 or 1:3 to remain profitable after costs. A mean-reversion or scalping approach with a 60 percent plus win rate can sustain ratios closer to 1:1. The desk recommends calculating expectancy rather than fixating on the ratio alone, since the two metrics must be assessed together.
Does a higher risk reward ratio mean a better trade?
Not necessarily. A 1:10 ratio looks attractive on paper but typically implies a target far from current price, which lowers the probability of the trade reaching it. Pushing targets further to inflate the ratio without structural justification reduces win rate faster than it improves payoff. The desk treats the ratio as a constraint, not a goal: it should reflect the actual structure of the market, not be engineered for appearance.
How does risk reward ratio interact with win rate?
The two metrics together define expectancy, which is the average outcome per trade. Expectancy equals win rate times average win minus loss rate times average loss. A strategy with a 1:3 ratio needs only a 26 percent win rate to break even before costs, while a 1:1 strategy needs above 50 percent. This is why the desk evaluates both numbers as a pair when assessing whether a system has a genuine edge.
Should the risk reward ratio include spread and commission?
Yes. Realised reward is reduced by the spread paid on entry and exit, plus any commission on raw spread accounts. On tight intraday setups where the stop sits twenty pips away, a one pip spread can shift the effective ratio meaningfully. The desk calculates the ratio using net distances after costs, which gives a truer picture of expectancy. This adjustment matters most for scalpers and least for swing traders holding multi-day positions.
