Risk management
The risk-reward ratio is one of the simplest and most powerful concepts in trading. It tells you how much you stand to gain for every dollar you risk. Once you understand it, you will never look at a trade the same way again.
The risk-reward ratio (often written as R:R) compares the potential loss of a trade to its potential gain. It is calculated by dividing the distance from your entry to your stop-loss by the distance from your entry to your profit target.
Risk-Reward Ratio = (Entry Price − Stop-Loss) ÷ (Target Price − Entry Price). A ratio of 1:2 means you are risking $1 to make $2. A ratio of 1:3 means you are risking $1 to make $3. The lower the first number relative to the second, the better the trade looks on paper.
You buy a stock at $50. Your stop-loss is at $48 (risking $2 per share). Your target is $56 (potential gain of $6 per share). R:R = $2 ÷ $6 = 1:3. For every dollar you risk, you stand to make three. This is a strong setup.
You buy at $120. Stop at $115 (risk $5). Target at $130 (reward $10). R:R = $5 ÷ $10 = 1:2. You need to be right on only about one-third of these trades to break even. More on that below.
You buy at $75. Stop at $70 (risk $5). Target at $78 (reward $3). R:R = $5 ÷ $3 ≈ 1:0.6. You are risking more than you stand to gain. You would need to win nearly two-thirds of the time just to break even. Most traders should skip this trade.
Use your broker platform or a simple spreadsheet to measure distances to stop and target before you enter — TradingSignalNow rows are for bias and levels; execution math stays on your side.
This table shows the minimum win rate you need to break even at each risk-reward ratio (expressed as risk:reward in line with the examples above).
Minimum win rate to break even (simplified model).
| Risk:Reward | Break-even win rate | Interpretation |
|---|---|---|
| 1:0.5 | 67% | Need to win about 2 out of 3 trades |
| 1:1 | 50% | Need to win half your trades |
| 1:1.5 | 40% | Can lose 3 out of 5 trades |
| 1:2 | 33% | Can lose 2 out of 3 trades |
| 1:3 | 25% | Can lose 3 out of 4 trades |
| 1:4 | 20% | Can lose 4 out of 5 trades |
| 1:5 | 17% | Can lose 5 out of 6 trades |
The idea behind the table: Break-Even Win Rate ≈ 1 ÷ (1 + Reward/Risk), where Reward/Risk is the “second number over the first” when you write the setup as risk:reward. At 1:2, that is 1 ÷ (1 + 2) ≈ 33%.
Many traders have a decent win rate but still lose money. The reason is almost always a bad risk-reward profile: small wins taken fast, large losses allowed to run. You might win 60% of trades and still finish negative if your average loss dwarfs your average win.
Trader A: wins 70% of trades. Average win: $200. Average loss: $600. After 100 trades: (70 × $200) − (30 × $600) = −$4,000. Trader B: wins 40%. Average win: $600. Average loss: $200. After 100 trades: (40 × $600) − (60 × $200) = +$12,000. Trader B wins less often but finishes far ahead — the difference is risk-reward discipline.
As a general rule, be careful with trades worse than about 1:1.5 on a risk:reward basis. Many swing traders use 1:2 as a minimum standard. Day traders with very high win-rate systems can sometimes work with 1:1, but they need consistency.
The best setups pair a clear pattern with a stop that makes sense and a target that is realistic — when the chart gives a tight stop and an obvious objective, the math tilts in your favor.
Before every trade, write down risk per share, reward per share, and the implied R:R. Compare the required break-even win rate to your actual historical win rate for similar setups. If you need 60% to break even but you only win 45% on that pattern, pass. Combine this with position sizing and you have a coherent risk framework — not personal advice; always verify with your broker and jurisdiction.
