How to calculate risk-to-reward, connect it with win rate and apply it to real trading decisions.
Introduction
A risk-to-reward ratio compares the amount you could lose on a trade with its potential gain. It is an essential planning tool, but it works best as part of a complete trading risk-management framework rather than as a stand-alone rule.
The ratio does not predict whether a trade will succeed. A realistic assessment must also consider win rate, position size, transaction costs, slippage, gaps and whether the target is achievable in the prevailing market.
Key Takeaways
Define the entry, stop and target before placing the trade.
Calculate potential reward from realistic price levels—not the ratio you want to see.
Judge risk-to-reward together with win rate and expectancy.
Use position sizing to keep the cash risk consistent when stop distances vary.
Treat every calculation as an estimate because execution and market gaps can change the result.

Video Summary
The video explains how entry, stop-loss and target prices determine the ratio, why waiting for a later entry can increase risk, and why risk-to-reward must be considered alongside win rate and expectancy. The central lesson is to define risk first and use realistic price levels rather than forcing a preferred ratio.
What Is a Risk-to-Reward Ratio?
Risk is the difference between the planned entry and stop-loss price. Potential reward is the difference between the entry and target price. Traders commonly express the relationship as 1:R.
Formula: potential reward ÷ amount at risk = reward multiple (R).
Risk £100 to make £100: 1:1.
Risk £100 to make £200: 1:2.
Risk £100 to make £300: 1:3.
A higher number is not automatically better. A distant target may look attractive mathematically while being unlikely to occur.
Worked Risk-to-Reward Example
Assume a trader identifies a breakout with an entry at $51, a technically justified stop at $49 and a target at $57.
Practical Checkpoint
Define the setup, entry and invalidation level before acting.
Compare the potential payoff with risk-reward planning.
Set the trade size using consistent position-sizing rules.
Risk per share: $51 − $49 = $2.
Potential reward per share: $57 − $51 = $6.
Risk-to-reward ratio: $2:$6, or 1:3.
If entry is delayed until $52.25 while the stop and target remain unchanged, risk becomes $3.25 and potential reward falls to $4.75. The ratio deteriorates to approximately 1:1.46. The setup has not changed, but paying a higher entry price materially changes its profile.
Why Entry Quality Matters
Chasing an extended candle often increases the distance to a logical stop while reducing the remaining distance to a realistic target. Passing on a late entry can therefore be a risk decision rather than an attempt to predict the next price move.
Risk-to-Reward, Win Rate and Expectancy
Risk-to-reward must be assessed alongside win rate. Expectancy estimates the average outcome per trade across a sufficiently large sample.
Expectancy = (win rate × average win) − (loss rate × average loss).
40% wins with an average 2R gain and 1R loss produces an expectancy of 0.2R before costs.
60% wins with an average 1R gain and 1R loss also produces 0.2R before costs.
30% wins with an average 3R gain and 1R loss produces 0.2R before costs.
Different combinations can therefore produce similar expectancy. The goal is not a perfect ratio on every trade; it is a repeatable process that keeps the probability of risk of ruin acceptably low.
Common Risk-to-Reward Mistakes
Selecting an unrealistic target simply to manufacture an attractive ratio.
Placing the stop at an arbitrary percentage rather than where the trade thesis is invalidated.
Moving the stop farther away after entry without reducing position size.
Ignoring spreads, commissions, slippage and overnight price gaps.
Taking profits early while repeatedly allowing losing trades to reach the full stop.
Assuming one high-reward winner proves that a strategy has positive expectancy.
A written stop-loss process and consistent trade-management rules help prevent emotional decisions from changing the original calculation.
Position Sizing From the Stop Distance
Once the stop distance is known, use position sizing to translate that price risk into a consistent cash amount. The Kelly Criterion is one reference method, although many traders use a more conservative fractional approach.
Position size = maximum account risk ÷ risk per share.
Evidence Check
Is the sample broad enough to include difficult markets?
Do the results include spreads, fees, slippage and failed signals?
Could hindsight, survivorship or selective examples explain the result?
£50,000 account with a 1% maximum risk: £500.
Entry at £50 and stop at £48: £2 risk per share.
£500 ÷ £2 = a maximum position of 250 shares before costs and slippage.
This calculation is illustrative, not a recommendation. Leverage, contract multipliers, liquidity and gaps can make actual losses larger than planned.
Applying the Ratio to Breakout Trading
In breakout trading, the consolidation area can provide a logical reference for invalidation while nearby resistance, volatility and market structure help assess the target. The strongest-looking breakout is not always the best trade if the entry is already too extended.

Pre-Trade Risk Checklist
Is the entry clearly defined?
Where is the trade thesis invalidated?
What is the risk per share or contract?
Is the target supported by price structure and volatility?
What position size keeps account risk within the chosen limit?
Does the trade still make sense after costs and possible slippage?
Will the plan remain unchanged if the first few minutes move against the position?
Frequently Asked Questions
What is a good risk-to-reward ratio?
There is no universally best ratio. A useful ratio is based on a technically justified stop and a realistic target, then assessed alongside the strategy’s win rate, costs and historical expectancy.
How do you calculate a risk-to-reward ratio?
Subtract the stop price from the entry price to calculate risk, then subtract the entry price from the target to calculate potential reward. Divide potential reward by risk to obtain the reward multiple.
Is a 1:2 ratio always profitable?
No. Profitability also depends on win rate, transaction costs, slippage, execution and whether the stated targets are actually reached. Risk-to-reward is one input into expectancy, not a guarantee.
Does a higher risk-to-reward ratio mean a better trade?
Not necessarily. Moving the target farther away improves the ratio on paper but may reduce the probability of reaching it. The stop and target should reflect market structure rather than an arbitrary number.
How does position sizing relate to risk-to-reward?
The stop distance defines the risk per share or contract. Dividing the maximum acceptable account risk by that amount gives a position size designed to keep cash risk consistent across trades.

Practical Limitations
Historical examples, interviews, backtests and indicator results are educational illustrations rather than forecasts. Outcomes depend on the market, timeframe, data, transaction costs, financing, taxes and execution assumptions. Test complete rules across varied conditions and define the maximum acceptable account risk before taking a position.
Put This Into Practice
These ideas become more useful when selection, entry, stop placement, position sizing and trade management form one repeatable process. The Financial Wisdom Trading Blueprint connects those decisions in a practical weekly framework.

So something I have been wondering about is taking the trade when the breakout happens instead of waiting for the weekly candle to close. Obviously this will lower the overall win rate of the strategy but it will also insure lower entry prices for better risk/reward. Is the trade does fail that week there is nothing stopping us from taking the trade the next time it tries to break out assuming that the fundamentals have not changed much in a few weeks time. Let’s look at the AFL trade from last week. If the trade was take. on the initial break out we would have entered around 59.80 instead of 62.74 Clearly I understand that breakouts often fail and thi…
