A risk-reward ratio compares the amount a trade plans to lose if wrong with the amount it aims to gain if right. Risking $1 to make $2 is commonly described as 1:2. It describes payoff structure, not the probability of success.
How it works
Risk-reward must be evaluated together with win rate. A 1:3 payoff looks attractive, but a strategy that wins only 10% of the time can still lose money. A 1:1 strategy can work if the win rate and execution quality are strong enough.
The ratio should use realistic executable prices. A planned 2% stop and 4% target looks like 1:2, but if event slippage turns the actual loss into 3%, the realized ratio is worse than the plan.
Why it matters
The ratio forces a trader to define downside and upside before entry instead of focusing only on the profit scenario.
It also exposes fragile high-win-rate trades that collect many small gains but occasionally suffer losses large enough to erase them.
A simple market example
The July 29, 2026 FOMC meeting is a useful event-risk example. The Fed held the federal-funds target at 3.50%–3.75%, broadly as expected, but three policymakers dissented in favor of a 25-basis-point hike. The S&P 500 only pared part of its decline, the 10-year Treasury yield was still slightly higher, and the dollar fell. A trader could therefore be 'right' that the Fed would hold and still earn very little if that outcome was already priced in. The real pre-trade question is how much the position could lose on a surprise versus how much it could reasonably make on the expected outcome. That distance is the practical meaning of risk-reward.
Common mistakes
Creating a huge target price and calling the trade 1:5 or 1:10 without evidence that the target is realistically reachable.
Confusing risk-reward with win probability. The ratio tells you the size relationship between winners and losers, not how often each occurs.
Frequently asked questions
Is a 1:2 trade automatically good?
No. Win rate, execution costs, market regime, and the quality of the underlying edge still matter.
Is a higher risk-reward ratio always better?
No. Farther targets are usually less likely to be reached, so the ratio cannot be judged separately from probability.
What if the actual loss exceeds the planned stop?
Use the real fill to evaluate the strategy and incorporate slippage into future sizing and risk budgeting rather than keeping idealized numbers.
