The risk/reward ratio compares how much you stand to lose on a trade with how much you stand to gain. A 1:3 ratio means you risk $1 to make $3. It's one of the most important numbers in trading because it sets the win rate you need to be profitable.

## Risk/reward and break-even win rate

The higher your reward relative to risk, the fewer trades you need to win to come out ahead. The break-even win rate is 1 / (1 + R), where R is your reward:risk ratio.

- 1:1 → you need to win 50% of trades just to break even.
- 1:2 → break-even at ~33%.
- 1:3 → break-even at 25%.
- 1:5 → break-even at ~17%.

> A trader who wins only 40% of the time can still be very profitable at 1:3 risk/reward. Being right less often is fine if winners are bigger than losers.

## Placing your stop-loss

Your stop-loss defines the 'risk' side of the ratio, so place it where your trade idea is proven wrong — beyond a support level, a swing low, or a volatility-based distance — not at an arbitrary round number. Then set your take-profit to give you the reward multiple you're targeting.

## Tie it together with position sizing

Once your stop distance is set, position sizing decides how many units to buy so that hitting the stop only costs a fixed small percentage of your account. Risk/reward, stop placement and position size work as a system — get all three right and no single trade can hurt you badly.

## Frequently asked questions

### What is a good risk/reward ratio?

Many traders aim for at least 1:2 or 1:3, meaning potential reward is two to three times the risk. Higher ratios lower the win rate you need to be profitable.

### Where should I place my stop-loss?

At the price that proves your trade idea wrong — beyond a support/resistance level, swing point, or a volatility-based distance — rather than an arbitrary amount. That makes the risk side of your ratio meaningful.

### Can a low win rate still be profitable?

Yes. With a 1:3 risk/reward, you only need to win about 25% of trades to break even, so a strategy that wins 40% can be very profitable if it sticks to that ratio.
