Position Sizing Rules for Success

Master these four rules and you'll never blow an account.

The 1% Rule

Never risk more than 1-2% of your account on a single trade. This ensures you can survive a losing streak without blowing your account.

Stop Loss First

Always set your stop loss BEFORE calculating position size. Your stop loss determines your risk, not the other way around.

Stay Consistent

Don't increase position size after wins or decrease after losses. Emotional sizing leads to blown accounts.

Account for Spreads

Your actual risk includes the spread. Add spread pips to your stop loss for more accurate risk calculation.

The Position Size Formula

Position Size = (Account Balance × Risk %) (Stop Loss in Pips × Pip Value)

Example: $10,000 account × 1% risk = $100 risk ÷ (50 pips × $10/pip) = 0.20 lots
