The risk/reward ratio compares what you risk to what you aim for on a trade. It's one of the most misunderstood concepts in trading, and one of the most powerful: handled well, it makes you profitable even while being wrong more often than not. As long as you avoid its traps, starting with the ratio that looks great on paper but never actually happens.
- You don't need to be right often: a 1:2 ratio makes you profitable from around a 34% win rate.
- Ratio and win rate are inseparable: one means strictly nothing without the other.
- Beware the unrealistic ratio: a target too far away collapses your win rate and destroys expectancy.
- What matters is the realized ratio, not the one you had in mind at entry.
The risk/reward ratio compares what you risk to what you aim for on a trade. If you risk 100 to target 200, your ratio is 1 to 2. It's simple to state, yet almost everyone uses it wrong: either they look at it alone, without crossing it with their hit rate, or they write a beautiful 1:5 on their plan when the market never actually gives it.
Understanding it changes how you judge your trades: you stop trying to 'be right' and start hunting for favorable asymmetries. This guide breaks down what the ratio really means, why it transforms your profitability, its mechanical link with win rate, the gap between planned and actual ratio, and how to measure it honestly instead of kidding yourself.
What the ratio really means
The risk/reward ratio is the relationship between two price distances: the one separating you from your stop loss (what you risk) and the one separating you from your target (what you aim for). If your stop is 20 pips away and your target 40 pips away, your ratio is 1:2. It's a measure of asymmetry: it tells you how much you make per unit of risk when the trade works.
The word 'reward' is misleading: it isn't a guaranteed gain but a potential one, the gain you'll get if price reaches your target before your stop. A 1:3 ratio doesn't mean you'll make three times your stake, it means that if this trade wins, it will make three times what a losing trade cost you. That nuance is crucial for everything that follows.
Why it changes your profitability
A good ratio lets you lose more often than you win while staying profitable. With a 1-to-2 ratio, you can be wrong 6 times out of 10 and still make money: your four winners at +2 bring 8 units, your six losers at -1 cost 6, leaving you +2. It's liberating, because it breaks the obsession with being right.
Most beginners do the opposite: they cut winners fast (fearing they'll evaporate) and let losers run (hoping they'll come back). Trade after trade, they build an inverted ratio where every gain is small and every loss is big. Even with an excellent hit rate, that profile ends up in the red. Taking care of your ratio simply means you stop sabotaging yourself on that side.
The inseparable link with win rate
Ratio and hit rate are two sides of the same coin: neither means anything on its own. A high win rate with a bad ratio can perfectly well lose money; a low win rate with a good ratio can make it steadily. What decides is their combination, which we call expectancy.
Every ratio has its breakeven point, the minimum win rate below which you lose. Here are the benchmarks worth knowing by heart:
| Risk/reward ratio | Breakeven win rate | What it means |
|---|---|---|
| 1:1 | 50% | You must win more than one trade in two |
| 1:1.5 | 40% | Comfortable margin for most styles |
| 1:2 | ≈ 34% | One in three winners is enough |
| 1:3 | 25% | One in four winners is enough |
| 1:5 | ≈ 17% | Profitable on paper, rarely reached |
The formula is simple: breakeven = 1 / (1 + ratio). For a 1:2, that's 1 / 3 ≈ 33%. Above that win rate you're a winner; below it, a loser. Above all, remember the logic: the higher your ratio, the more often you can afford to lose, but only under one condition nobody ever mentions.
The unrealistic-ratio trap
Aiming for huge ratios (1:8, 1:10) sounds brilliant: the table above tells you a 1:10 is profitable with just a 10% hit rate. The problem is that win rate isn't independent of ratio. The further your target, the more chances price has to reverse before reaching it. A 1:10 target is mechanically hit far less often than a 1:2 one.
In other words, you don't choose your ratio and your win rate separately: when you raise one, you lower the other. So the best ratio isn't the biggest, it's the one that maximizes expectancy on your market and your style. For many intraday traders, that optimum sits between 1:1.5 and 1:3, rarely beyond. Above that, the win rate collapses faster than the ratio grows, and expectancy falls back down.
A 1:10 ratio with a 5% hit rate is a dreamer's ratio. A 1:2 ratio with a 45% hit rate is a profitable trader's ratio.
Planned ratio versus realized ratio
Here's the point almost nobody measures. The ratio you write on your plan before entering (the planned ratio) has almost nothing to do with the ratio you actually realize. You exit before target because it's stressful, you move your stop 'just a little', you cut a +3 trade at +1, you let a gain drift back to entry. In the end, the realized ratio is systematically lower than the planned one.
That's why judging your trading on intentions is useless. A 1:3 plan executed like a 1:1 is a 1:1 plan. The only data that counts is the average ratio of your actually closed trades. And it's almost always an unpleasant revelation the first time you measure it: most traders discover they realize a far lower ratio than they thought they held.
How to set a reachable ratio
A good ratio isn't decided at random or out of ambition. It's derived from your method and verified on your data. Here's the healthy approach:
- Place your stop where your thesis is invalidated, never at an arbitrary distance chosen to 'make a nice ratio'.
- Place your target on a real market level (support, resistance, liquidity), not on a theoretical multiple of your risk.
- Compute the resulting ratio. If it's bad, don't cheat on the stop: skip the trade.
- Over 30 to 50 trades, measure your average realized ratio and your real win rate, then check that expectancy is positive.
- Adjust your method, not your numbers: if the real ratio is too low, the problem is in your exits, not in your spreadsheet.
Thinking in R: the right unit
The cleanest way to use all this is to measure your trades in R, where 1 R is your initial risk (the distance between entry and stop, expressed in money). A trade that wins twice your risk is +2 R; a stopped-out trade is -1 R; a trade cut halfway is +0.5 R. Thinking in R, you compare all your trades on the same scale, whatever their size.
R turns the ratio from an intention into a measurement. Instead of saying 'I aim for 1:2', you can say 'my average realized R is +0.6 over my last 40 trades'. That's a concrete number, comparable over time, that tells you whether you're improving or kidding yourself. Add up your R over a period and you get your performance directly in units of risk, independent of your position size.
Classic mistakes to avoid
- Judging the ratio alone: a ratio without a win rate says nothing. Always read both together.
- Widening the stop to 'improve' the ratio: you reduce your displayed risk but increase your real loss. That's lying to yourself.
- Aiming too far: the dream ratio that never happens costs more than a modest ratio that does.
- Moving the target mid-trade: every time you cut a winner early, you degrade your realized ratio.
- Never measuring the realized side: without data on your closed trades, your ratio is just an opinion.
The ratio varies by trading style
There's no universal ideal ratio, because the right ratio depends directly on your style. A scalper, aiming for small moves with a high win rate, naturally works with modest ratios (often around 1:1) and compensates with a high hit rate. A trend follower, letting big moves run with a low win rate, needs high ratios (1:3, 1:5) to be profitable despite their many small losses. Both can win, with opposite ratios.
The mistake would be to slap a 'recommended' ratio onto your method without regard for its nature. A scalper forcing themselves to aim for 1:3 would miss most of their targets and collapse their win rate; a trend follower cutting at 1:1 would kill their edge. The right ratio isn't a magic number, it's the one that fits your style and that your data confirms as profitable. Start by understanding how you win, then calibrate your ratio accordingly, never the reverse.
The ratio isn't fixed during the trade
The ratio you compute at entry is only a starting point, not a rigid constraint for the trade's whole life. As price evolves and new information arrives, the remaining risk/reward changes. A trade entered at 1:3 that has already covered half the distance now offers only 1:1 on the rest: the question is no longer the same, and managing that evolution intelligently is part of the craft.
That's where tools like moving to breakeven (shifting your stop to entry once a certain profit is reached) or partial exits (securing part of the gain while letting the rest run) come in. These techniques let you adjust the risk/reward profile along the way without ever moving a stop against yourself. Handled well, they improve your realized ratio; handled badly, they make you cut too early. The rule stays the same: decide these adjustments cold, in your plan, never under the sting of emotion.
Ratio and transaction fees
A point beginners systematically forget: fees erode your real ratio. The spread, commissions and swap add to your risk and subtract from your gain, so a theoretical 1:2 ratio can turn into a real 1:1.7 once fees are accounted for. On small moves, where fees represent a large share of the distance covered, this effect is even more pronounced and can be enough to flip a strategy from profitable to losing.
It's one more reason to measure your realized ratio on your actually closed trades, fees included, rather than trusting your plan's theoretical ratio. The ratio that counts isn't the one you had in mind at entry, it's the one that appears in your account after everything has been paid. Ignoring fees in your ratio calculation means telling yourself a flattering story that doesn't match what your capital actually feels.
Measuring it automatically with Tradoshi
Computing your real R by hand is tedious and error-prone, which is exactly why most traders never do it. Tradoshi does it for you: it reads your stop loss from your orders and derives your R-multiple on every trade, without you entering anything. You see your realized ratio, not the one you imagined.
- Automatic R-multiple: your initial risk is read from your stops, your R is computed on every closed trade.
- Average realized ratio: you see at a glance whether your exits keep their promises or betray them.
- Crossed with win rate: ratio and hit rate are shown together, never one without the other.
- Tracked over time: your average R per period shows you whether you're truly improving.
Frequently asked questions
Can a 1:1 ratio be profitable?
Yes, provided you have a win rate above 50%. The ratio is never judged alone: it's the combination of ratio and win rate that determines expectancy. A 1:1 at 55% is a winner; the same at 45% is a loser.
What's a good risk/reward ratio?
There's no magic number, but aiming for at least 1:1.5 or 1:2 is a healthy benchmark for most styles. The best ratio is the one that stays reachable on your market while keeping a decent win rate. The balance between the two matters more than the displayed number.
Why does my win rate drop when I aim further?
Because the further your target, the more chances price has to reverse before reaching it. A 1:5 target is mechanically hit less often than a 1:2 one. That's the fundamental trade-off between ratio and hit rate: you can't maximize both at once.
What exactly is an R?
1 R is your initial risk on a trade, i.e. the distance between your entry and your stop, expressed in money. A +2 R gain means you made twice what you risked. Thinking in R lets you compare trades of different sizes on the same scale.
Are planned and actual ratios often different?
Yes, very often, and almost always in the wrong direction. You exit before target, move a stop, cut early: the realized ratio drifts from the planned one. That's why measuring your real R, from your executed trades, is far more useful than the ratio you had in mind at entry.
Should I widen my stop to improve my ratio?
No, that's the classic mistake. Widening the stop reduces your displayed ratio but increases your real loss in money. The stop goes where your thesis is invalidated, not where it makes the ratio look nice. If the resulting ratio is bad, the right answer is to skip the trade.
How do I compute a ratio's breakeven point?
The formula is: breakeven = 1 / (1 + ratio). For a 1:2, that's 1 / 3 ≈ 33%. Above that win rate you win, below it you lose. It's a useful benchmark, but remember that a higher ratio mechanically lowers your real win rate.
