Risk-Reward Ratio (Trading)
Compares the potential profit of a trade to its potential loss, a core risk-management calculation for crypto and stock traders.
Interpretation
R:R = (Target Price − Entry Price) / (Entry Price − Stop-Loss Price). The ratio of potential profit to potential loss. Used in trading to evaluate trade setups.

What it means
The risk‑reward ratio is a fundamental concept in trading that compares the potential profit of a trade to the potential loss. A ratio of 2:1 means the target profit is twice the stop‑loss distance. This is used to evaluate whether a trade is worth taking. A good risk‑reward ratio can make a strategy profitable even with a low win rate. It is used in position sizing and in setting take‑profit and stop‑loss levels. Understanding this is essential for disciplined trading and for managing risk effectively.

Common mistakes
- Target price: The price at which you plan to take profit.
- Entry price: Your average purchase price.
- Stop‑loss: The price at which you will exit to limit losses.
- Result: A ratio >1 means the potential reward exceeds risk.
- Use absolute differences: Ensure numerator and denominator are positive.
Applications
The risk‑reward ratio (R:R) compares the potential profit of a trade to its potential loss, calculated as the distance from entry to target divided by the distance from entry to stop‑loss. This is a cornerstone of trading discipline, helping traders evaluate whether a trade is worth taking. By setting a favourable R:R (e.g., 2:1 or higher), traders ensure that their wins, when they occur, are larger than their losses. This ratio is used to filter trade setups and to manage position sizing. It also helps in backtesting strategies and in developing a consistent trading plan. Understanding the R:R ratio is essential for profitable trading, as it directly impacts the expectancy of a system.

Frequently Asked Questions
The ratio is (Target Price - Entry Price) / (Entry Price - Stop-Loss Price). This tells you how many dollars you stand to gain for every dollar you risk. A ratio of 2:1 means you risk $1 to gain $2.
Many traders look for at least 2:1, but some require 3:1 or higher. The higher the ratio, the lower your win rate needs to be to remain profitable. The choice depends on your strategy.
A wider stop-loss increases the risk (denominator), reducing the ratio for the same target. A tighter stop-loss improves the ratio but increases the chance of being stopped out prematurely.
Yes, it's part of position sizing. You decide how much of your account you are willing to risk (e.g., 1%), then use that risk amount and the stop-loss distance to calculate the position size.
No. You also need to consider the probability of the trade working out (win rate). A high risk-reward ratio with a very low win rate may still be unprofitable. Combine both for better analysis.
It becomes dynamic. You can use your initial stop-loss for the risk calculation, and the target price for the reward. The ratio at entry is fixed; afterwards, it improves as the stop moves up.
For a short, the formula is (Entry Price - Target Price) / (Stop-Loss Price - Entry Price). The logic is the same: potential gain divided by potential loss.
You should recalculate if you move your stop-loss or target. Some traders re-evaluate after significant price moves to lock in profits or adjust targets.
