Why Position Sizing Matters
Position sizing is the most important risk management tool. It determines how much you can lose on a single trade. Even with a 50% win rate, proper position sizing can make you profitable over time.
The 2% Rule
Most professional investors risk only 1-2% per trade. This means even 10 consecutive losses only costs 20% of your account - recoverable! Compare this to risking 10% per trade where 5 losses = 50% drawdown.
⚠️ Risk Warning
Trading involves substantial risk of loss. This calculator is for educational purposes only. Past performance does not guarantee future results. Only trade with capital you can afford to lose.
