Position Sizing Rules

Professional traders risk 1-2% per trade. This ensures you can survive 50+ consecutive losses without blowing your account. Position size = Risk Amount ÷ (Stop Loss pips × Pip Value).

What is the 1% rule in forex?

Never risk more than 1% of your account on a single trade. With $10,000, max risk = $100 per trade. This rule preserves capital during losing streaks.

How do I use this with MetaTrader?

Enter your account balance, set risk %, enter your stop loss in pips for the trade setup. Use the resulting lot size directly in your MT4/MT5 order.

What lot size is right for beginners?

Beginners should start with micro lots (0.01) and risk no more than 1-2%. As you gain confidence and consistency, you can gradually increase position size.
