Position Sizing: The Skill That Keeps You Alive
Risk a fixed percentage, size from your stop, and let every trade carry the same weight — no more emotional bet-sizing.
Why Sizing Beats Everything
You can have a brilliant strategy and still blow up with bad sizing. Position size decides how much of your account a single mistake costs.
Consistent sizing is what turns a good win rate into a survivable equity curve.
Fixed-Percentage Risk
The standard: risk the same small % (commonly 0.5–1%) on every trade.
- Account = $10,000, risk = 1% → $100 at risk per trade.
- Stop = 50 pips → size so 50 pips = $100.
Every trade now risks the same amount, no matter the pair or setup.
Size From The Stop, Not The Dream
Place your stop where the trade is invalidated first, then size the position to fit your risk. Never pick a lot size and squeeze a stop into it.
Surviving Losing Streaks
Even a 50% strategy can lose six in a row. At 1% risk that is a 6% drawdown — recoverable. At 10% risk it is a 48% hole — brutal.
Small fixed risk keeps you in the game long enough to let your edge play out.
