The risk-reward ratio (RRR) expresses how much potential profit you are targeting relative to the amount you are risking on a trade. A 2:1 risk-reward ratio means you are targeting a gain of AUD 2 for every AUD 1 you risk losing. A 3:1 ratio means AUD 3 of potential gain for every AUD 1 of risk.
The ratio is calculated from three points: your entry price, your stop loss (defining maximum loss), and your take profit target (defining the expected gain). Risk = entry price minus stop loss price. Reward = take profit price minus entry price. Ratio = reward divided by risk.
The risk-reward ratio is one of the most fundamental concepts in professional trading because it determines whether a trading strategy is mathematically profitable over time. A trader with a 50% win rate and a 2:1 RRR will be profitable over the long run. A trader with a 70% win rate but a 0.5:1 RRR (risking more than they can win) will lose money over time despite winning more often than they lose.
The minimum acceptable risk-reward ratio for most traders is 2:1. Below this threshold, trading costs (fees, spreads, slippage) and the reality that many trades miss their targets by small amounts make it difficult to achieve consistent profitability.
At a 2:1 RRR with a 50% win rate: 100 trades, 50 winners at AUD 200 gain, 50 losers at AUD 100 loss. Net result: AUD 10,000 gain minus AUD 5,000 loss = AUD 5,000 profit before fees. The same 50% win rate at 1:1 RRR: breakeven before fees, likely a loss after fees. Trading fees across a crypto exchange at 0.1% per side and considering the hidden costs of crypto trading means 1:1 strategies are economically marginal even before accounting for any statistical variance.
At 3:1 RRR, you can be wrong 60% of the time and still be profitable: 60 losers at AUD 100 = AUD 6,000 lost. 40 winners at AUD 300 = AUD 12,000 gained. Net: AUD 6,000 profit. High-quality setups with 3:1 or better ratios should be prioritised over marginal setups with lower ratios.

The reward side of the ratio must be anchored to a realistic, technically or fundamentally justified target rather than an arbitrary number. Setting a target at the next significant resistance level on a chart ensures the target reflects where actual sellers are likely to emerge, not just a level that produces a favourable-looking ratio.
Common technical target-setting methods include measured moves (where the expected gain equals the height of a pattern such as a head and shoulders or cup-and-handle), Fibonacci extension levels from the previous swing, and prior resistance levels that now act as targets. Each of these methods grounds the target in market structure rather than wishful thinking.
In a strong bull market with broad momentum, extending targets to 3:1 or 4:1 ratios makes sense because trends carry further. In choppy or ranging conditions, more conservative 2:1 targets are more likely to be hit before the price reverses. Calibrating the target to the prevailing market conditions improves the probability that the reward side is achievable.
A critical discipline is calculating the risk-reward ratio before entering any trade, not after. This prevents entering trades that look promising in the moment but have unfavourable ratios when analysed objectively.
The process: identify the entry level, define the stop loss at a technically justified level (below support for a long trade, above resistance for a short trade), define the take profit target, then calculate the ratio. If the ratio is below 2:1, either the stop loss is too wide (entry is too far from support), the target is too conservative, or the trade is not worth taking.
This pre-trade analysis also connects directly to position sizing. Once the stop loss level is defined, position size is calculated using the 1% risk rule to ensure the stop loss amount equals no more than 1% of total capital. The risk-reward ratio and the 1% rule work together: the ratio determines whether a trade is worth taking and the 1% rule determines how big the position should be.
Risk-reward ratio and win rate are the two variables that determine trading profitability over time. Every trader must understand the relationship between them for their own strategy.
High win rate, low RRR: day traders using scalping strategies often have 60-70% win rates but achieve 1:1 to 1.5:1 ratios per trade. Their profitability comes from volume and consistency, not individual trade size.
Low win rate, high RRR: trend followers often have 30-40% win rates but achieve 5:1 or higher ratios on their winning trades. Their profitability comes from letting winners run far and cutting losers quickly.
Both approaches can work if applied consistently. The mistake is having a low win rate AND a low RRR: being wrong often AND losing more per loss than you gain per win. This combination cannot be profitable regardless of other factors. Understanding your own trading style and what RRR is consistent with it guides the calibration of targets and stop losses.
Combining the risk-reward framework with the buy-the-dip strategy, momentum strategy, or any other entry methodology creates a complete trade management system. The entry methodology identifies where to get in; the risk-reward framework governs how to manage and exit.
