Frequently Asked Questions
How do I calculate position size from risk?
Position size = max loss / loss per unit. Loss per unit = |entry − stop| + fees. This ensures your worst-case loss never exceeds your limit.
What is the 1–2% rule?
Risk no more than 1–2% of your account per trade. If your account is $10,000 and you risk 1%, your max loss per trade is $100.
What are OKX perpetual futures fees?
OKX charges maker fee 0.02% and taker fee 0.05%. Maximum leverage is 100×. This calculator uses these defaults but you can adjust them for your actual rate tier.
