Size your positions based on your actual drawdown allowance
Heads up: Prop firms advertise large account sizes (e.g. "$100K account"), but your real capital at risk is the drawdown limit — typically only 4–10% of that number. A "$100K account" with a 5% max drawdown means you have $5,000 to work with before you breach.
