The 1% Rule in Trading: Why Small Risk Per Trade Protects Your Account
The 1% rule is simple: never risk more than 1% of your trading account on a single trade. It does not mean you can only buy 1% of your account's worth — it means the loss you take if your stop-loss is hit should be no more than 1%.
What the rule really means
With a $20,000 account, 1% is $200. You might buy $5,000 or $10,000 of a coin, as long as your stop-loss is placed so that hitting it costs about $200.
Position size = (Account × 1%) ÷ Stop distance per unit

Every strategy has losing streaks. The question is whether you survive them.
| Consecutive losses | Account left at 1% risk | At 5% risk | At 10% risk |
|---|---|---|---|
| 5 | 95.1% | 77.4% | 59.0% |
| 10 | 90.4% | 59.9% | 34.9% |
| 15 | 86.0% | 46.3% | 20.6% |
| 20 | 81.8% | 35.8% | 12.2% |
At 1% risk, even 20 losses in a row leave over 80% of your account. At 10%, ten losses leave about a third.
Recovering from drawdowns
Losses are harder to recover than they look. A 10% drawdown needs an 11% gain to recover. A 65% drawdown needs a 186% gain. Small risk per trade keeps drawdowns in a range where recovery is realistic.
Why 1% works psychologically
When each loss is small, it is easier to follow your plan: take the stop, avoid revenge trading and keep executing your strategy. Large risks create stress, and stress causes mistakes.
Variations
- 0.5% rule: common for new traders or highly volatile assets.
- 2% rule: used by some experienced traders with proven strategies.
- Reduced risk after losses: some traders cut risk to 0.5% after a set drawdown and restore it after recovery.
Applying it to crypto futures
The rule works the same way with leverage. Leverage reduces your margin but should not change your risk. With a $10,000 account and a 1% rule, a trade stopped out should cost about $100 whether you use 2× or 10×. Make sure your liquidation price sits beyond your stop. Read liquidation price explained.
Limits of the rule
- Gaps and wicks. In extreme moves, your stop may fill worse than planned, causing a loss larger than 1%.
- Correlated trades. Five 1% trades in highly correlated coins can behave like one 5% trade.
- It is not a strategy. The 1% rule controls damage; it does not create an edge on its own.
