What “risk reward” means in forex
Risk reward in forex usually refers to a comparison between the potential upside of a trade idea and the potential downside. The key is that both amounts should be measurable from the same trade reference points (typically entry, stop-loss level, and take-profit level).
In practice, people often express risk reward as a ratio:
- Risk: the absolute distance (or monetary amount) from entry to the stop-loss.
- Reward: the absolute distance (or monetary amount) from entry to the take-profit.
Because currencies move in both directions, you should treat “distance” as a magnitude. For example, if the stop is below entry for a long trade, the risk distance is entry minus stop (a positive number).
The calculation method
Step 1: Define your measurement basis
You can calculate the ratio using either:
- Price distance (in pips or points), or
- Monetary amount (profit or loss in account currency) for the same position size.
Using price distance is common for conceptual understanding. Using monetary amounts is useful if you want the ratio to reflect actual money rather than just movement.
Step 2: Compute reward and risk
Let:
- R = reward (distance or money)
- D = risk (distance or money)
Then:
- Reward: absolute(Entry − Target)
- Risk: absolute(Entry − Stop)
Step 3: Compute the risk-reward ratio
- Risk-Reward Ratio = Reward ÷ Risk
If Reward is 2 units and Risk is 1 unit, the ratio is 2:1.
Example and independent checks
Example using price distance
Assume a setup with:
- Entry
- Stop-loss at a distance of 20 pips from entry
- Take-profit at a distance of 40 pips from entry
Risk = 20, Reward = 40. Risk-Reward Ratio = 40 ÷ 20 = 2:1.
Example using money (conceptual)
If you compute monetary loss and gain from the same position size, you should:
- Use the same entry, stop, and target levels.
- Ensure the position size is unchanged.
- Use consistent conversion (so gains and losses are in the same account currency).
Consistency checks
To keep the ratio meaningful, verify:
- Both distances are measured from the same entry price.
- Stop and target are on the correct sides of entry for the intended direction.
- Risk is not zero (a zero-risk setup makes the ratio undefined).
Limitations and risks
Risk-reward calculation is a simplified model. It focuses on predefined levels (entry, stop, take-profit), but real outcomes can differ because prices may gap, spreads may widen, and execution may occur at different levels than expected.
Also, the ratio alone does not determine results. It does not include:
- probability of reaching the target versus the stop,
- time spent in the trade,
- transaction costs (spread, commissions) or slippage,
- how frequently the trade plan will be followed.
A practical verification method is to evaluate how your measured risk and reward relate to your actual execution costs in backtests or historical observation for your specific assumptions—without assuming future performance.
If you want, share a numeric scenario (entry, stop, target, and whether you prefer pips or money). I can show how to compute the ratio using the same definitions above.
