Every blown account tells the same story: not a bad strategy, but bad size. The 1% rule is the single habit that separates traders who survive their learning curve from those who fund it. It's one sentence long.
What the rule says
Risk no more than 1% of your account on any single trade. “Risk” is not what you invest — it's what you lose if your stop is hit. On a $1,000 account, that's a maximum $10 loss per trade, and your position size is whatever makes that true.
The math that saves accounts
| Risk per trade | 10-loss streak costs | Gain needed to recover |
|---|---|---|
| 1% | −9.6% | +10.6% |
| 2% | −18.3% | +22.4% |
| 5% | −40.1% | +67% |
| 10% | −65.1% | +186% |
Loss streaks are not bad luck — they're statistics. A strategy with a genuine 50% win rate will hit 8–10 consecutive losses multiple times per year. At 1% risk that's a bad month; at 5% it's account-ending. Same strategy, same trades — only sizing differs.
Apply it in 4 steps (per trade)
- Set the risk budget: balance × 1%. Write the dollar figure down.
- Find the stop on the chart — at structure (swing high/low), never at a round number. Count the pips.
- Size with the Position Size Calculator: balance, risk %, stop → exact lots (it rounds down and warns below 0.01).
- Verify margin with the Margin Calculator — if the trade doesn't fit the account, skip it. Skipping is a position too.
When to risk less than 1%
- Under $500: 0.5%, or a cent account — minimum lot sizes make 1% awkward on tiny balances.
- First 3 months live: you're paying tuition; pay it slowly.
- Prop-firm accounts: daily drawdown caps (often 5%) make 0.5–1% the professional norm.
- After 2 losses in a week: halve size until your next winner. Tilt-proofing is sizing's real job.
Two myths worth killing
“1% is for cowards.” Funds risk 0.25–0.5% per position with teams of analysts. You, alone, at 1% — you're already the aggressive one.
“I'll size up when I'm profitable.” Profitability comes from surviving. The account that compounds +3%/month at 1% risk beats the one that made +40% in March and died in April. Run your own numbers in the Compounding Planner.
Frequently asked questions — 1% Rule
Is risking 1% per trade good?
Yes — it is the standard recommendation for retail traders because a 10-loss streak costs about 10% of the account, which is painful but fully recoverable. Beginners with small accounts often do better at 0.5%.
How do I calculate 1% risk position size?
Lots = (balance × 1%) ÷ (stop in pips × pip value). Example: $1,000, 25-pip stop, EURUSD → $10 ÷ $250 = 0.04 lots.
When should I risk more than 1%?
Almost never before you have 12+ months of profitable, journaled results. Even then, most professionals cap at 2%. Aggressive risk is how good strategies die in bad months.
