Reward-to-Risk & R-Multiples,
geometry is not probability.
Reward-to-risk compares a potential gain with a defined amount of risk. An R-multiple expresses an outcome relative to that initial risk. A 2R target means twice the risk distance or amount. It does not mean the trade is twice as likely to win.
Quick answer
What does 2R mean?
If 1R represents the amount you defined as initial risk, a +2R outcome gains twice that amount and a -1R outcome loses one unit of risk. The framework makes different trades easier to compare without requiring the same dollar size.
What does reward-to-risk actually tell you?
It tells you the geometry of the proposed outcome. For example, risking $1 of price movement to target $2 produces a 2:1 reward-to-risk ratio before costs and execution effects.
It does not tell you whether the target is realistic or how often that outcome occurs.

You can lose more often than you win. And still make money.
A good strategy is not simply one that guesses correctly most of the time. What matters is how often it wins, how much it makes when it wins, how much it loses when it doesn’t, and what it costs to execute.
Win rate across the bottom · illustrative net expectancy (A$) above each bar · zero line separates gains and losses
Illustrative only. Assumes each winner realises +2R, each loser −1R, A$100 initial risk per trade and A$10 all-in round-trip costs. This is a worked mathematical example, not observed BowerLine performance.
What’s the minimum win rate to break even?
Without costs, a strategy that actually earns 2R on wins and loses 1R on losses needs to win one trade in three (33.3%) just to break even. Trading costs push that threshold higher.
| Average win | Average loss | Break-even win rate |
|---|---|---|
| +1R | −1R | 50% |
| +1.5R | −1R | 40% |
| +2R | −1R | 33.3% |
| +3R | −1R | 25% |
These break-even rates exclude costs. Under the bar chart’s A$100 risk/A$10 cost assumptions, break-even rises to approximately 36.7% for a 2R winner.
But a good-looking target isn’t proof of an edge.
The math only works if the trades actually realise those payoffs. A stock finishing higher after five days is not the same thing as a trade reaching its profit target before its stop. A backtest isn’t a live result. And a strategy that rises less than the market may not have demonstrated useful stock-selection skill.
BowerLine’s test: show verified entry and exit evidence, net results after brokerage and slippage, the number of observations, how often the stop or 2R target came first, and performance compared with a relevant market benchmark. Until then, call a promising idea a hypothesis — not a proven edge.

Why does win rate matter too?
A strategy with large wins can still lose money if wins occur too rarely. A strategy with many small wins can still fail if occasional losses are huge. Long-term expectancy depends on the combination of win frequency, average win, average loss and costs.
Common mistake
Do not choose a target just because it creates a prettier R ratio.
A 5R target drawn in empty space is not automatically better than a 2R target near a meaningful structural level. The target still needs market context.
Worked technical example
See how an R-multiple starts with volatility.
A 2R target is only useful once the initial risk distance is defined. The historical BowerLine PME alert shows the entire process: a 14-day ATR of A$6.6357, a suggested A$169.06 stop and an A$208.87 2R target from a reference price of A$182.33.
