How Position Sizing Works
Position sizing ensures you never risk more than a predetermined percentage of your account on any single trade.
Formula:
Position Size = (Account × Risk %) ÷ (Entry Price − Stop Loss Price)The 1% Rule
Most professional traders risk no more than 1% of their account per trade. With a $10,000 account, this means risking only $100 per trade. Even after 10 consecutive losses, you'd still have $9,000 — staying in the game.
Why It Matters
- Consistent risk — Every trade risks the same percentage regardless of asset or timeframe
- Survivable drawdowns — Even long losing streaks won't blow your account
- Emotional control — Knowing your max loss reduces trading anxiety
