The Art of Position Sizing
Master the most important skill in trading: protecting your capital.
Position sizing determines exactly how much to invest per trade based on your risk tolerance. The 1% rule — never risk more than 1% of your portfolio on a single trade — is the foundation of professional risk management. Use our calculator to find your ideal position size.
What Is the 1% Rule?
Professional traders rarely risk more than 1% to 2% of their total account balance on a single trade. This ensures that even a string of losses won't blow up your account.
- Preserve your capital for the next day
- Reduce emotional stress during trades
- Allow for a series of losses without bankruptcy
- Focus on process rather than money
How Do You Calculate Position Size?
To calculate your size, you need three numbers: your account balance, the percentage you want to risk, and the distance to your stop loss.
Position Size = (Account Balance * Risk %) / (Entry Price - Stop Loss Price)What Is a Position Sizing Example?
Account: $10,000. Risk: 1% ($100). Entry: $50,000. Stop Loss: $49,000. Your position size should be 0.1 BTC ($5,000). If you hit your stop, you only lose $100.
What Are the Benefits of Proper Position Sizing?
- Consistency in your trading results
- Mathematical edge over the market
- Better sleep at night
- Professional approach to risk
| Account Balance | Risk % | Risk $ | Stop Loss | Position Size |
|---|---|---|---|---|
| $5,000 | 1% | $50 | 2% | $2,500 |
| $5,000 | 2% | $100 | 2% | $5,000 |
| $10,000 | 1% | $100 | 2% | $5,000 |
| $10,000 | 2% | $200 | 2% | $10,000 |
| $50,000 | 1% | $500 | 5% | $10,000 |
| $50,000 | 2% | $1,000 | 5% | $20,000 |

FAQ
1. Why can't I just go "All In"?
Going "All In" is gambling, not trading. One bad move or market flash crash can wipe out your entire life savings.
2. What is a "Stop Loss"?
A stop loss is an automatic order to close your trade at a specific price to prevent further losses.
3. Should I change my risk % based on confidence?
Generally, no. Consistency is key. If you vary your risk, one large loss on a "confident" trade can erase many small wins.
4. Does this apply to HODLing?
While less critical for long-term investors, position sizing still helps you diversify and avoid over-exposure to a single asset.
5. Can I use leverage with this?
Yes, but your risk amount ($) remains the same. Leverage just allows you to open the same position size with less collateral.
