Position Sizing 101: The Key to Surviving Drawdowns

Position Sizing 101: The Key to Surviving Drawdowns

Most traders fail not because their strategy doesn't work, but because they don't size positions correctly. Position sizing is how you survive drawdowns and stay in the game long enough to profit.

The 1-2% Rule

Risk no more than 1-2% of your account per trade. If your account is $10,000, risk $100-200 per trade.

Why? Because even great traders have 5-10 consecutive losses. If you risk 5% per trade, five losses = 25% drawdown. At 10% per loss, ten losses = 100% account blow-up.

At 1% per loss, ten losses = 10% drawdown. You survive and can keep trading.

Position Size Calculation

Position Size = (Account Size × Risk %) / Distance to Stop Loss

Example: Account $10,000, Risk 1%, Stop Loss 2%

Position Size = ($10,000 × 0.01) / 0.02 = $5,000 notional ($100 risk)

If price moves against you 2%, you lose exactly $100 (1% of your account).

The 2% Rule Won't Make You Rich (And That's Okay)

A 2% per-trade strategy with 60% win rate makes ~1% monthly return. Over a year, that's ~12% return. It's boring. But it's safe. You'll still be trading in 5 years.

A 10% per-trade strategy makes ~5% monthly return. Sounds better. But one bad month and your account is half. Most traders blow up this way.

Scaling Up Over Time

Start at 1% per trade. After reaching $20,000, scale up to 1.5% per trade. After $50,000, scale to 2% per trade. This lets your profits compound while keeping drawdowns manageable.

Action Plan

Calculate your maximum risk per trade at 1% of your account. Commit to this for 3 months. Track your drawdown. Most traders find 1% keeps them calm and helps them execute their plan better.
