The Golden Rule
Never risk more than 1-2% of your total capital on a single trade.
With $10,000 total capital and 2% risk per trade:
- Maximum loss per trade = $200
Position Size Calculation
Position Size = (Account Balance x Risk %) / (Stop-Loss Distance x Leverage)
Example:
- Account: $10,000
- Risk per trade: 2% = $200
- Stop-loss: 5% from entry
- Leverage: 10x
Margin needed = $200 / (5% x 10) = $400 Position size = $400 x 10 = $4,000
If stopped out, you lose $200 (2% of capital).
Key Principles
- Define risk before entry: Know your maximum loss before placing a trade
- Scale with account size: As your account grows/shrinks, adjust position sizes
- Account for leverage: Higher leverage means less margin but same dollar risk
- Include fees: Factor in trading fees and funding rates
- Leave buffer: Never use 100% of your capital
Risk Tiers
| Risk Level | % Per Trade | Suitable For |
|---|---|---|
| Conservative | 0.5-1% | Beginners |
| Moderate | 1-2% | Intermediate |
| Aggressive | 2-5% | Experienced only |
| Reckless | 5%+ | Not recommended |
Common Mistakes
- Sizing by gut feeling: Always calculate mathematically
- Ignoring stop-loss distance: Position size must account for your stop
- Adding to losing positions: "Averaging down" increases risk
- Full account risk: Using all capital on one trade
- Increasing size after losses: Revenge trading is destructive
Practical Tips
- Use Binance's position calculator before each trade
- Keep a trading journal tracking your position sizes and outcomes
- Reduce position sizes during high volatility
- Start with minimum positions when learning
FAQ
Does leverage change my risk? Leverage amplifies gains AND losses per dollar of margin, but your actual dollar risk depends on position size and stop-loss, not leverage alone.
Should I use the same position size for all trades? Size based on risk per trade (% of capital) and stop-loss distance. This means different trades may have different position sizes.
How do I calculate position size for different leverage levels? At higher leverage, you need less margin for the same position size. But the dollar risk per percentage move stays the same.

- Use position sizing consistently -- discipline is key
- Reduce size during drawdowns -- protect remaining capital
- Keep records of all trades with position sizes and outcomes
