Position Size Calculator
Stop-loss based sizing: set how much of your account you risk to the stop, then get notional, quantity, and leverage for your margin. Optional take-profit shows risk:reward and reward at target. LeverUp liquidation is checked against your stop.

Worked example
Account $10,000, risk 1% → $100 at risk. Long BTC entry 60,000, stop 59,400 → stop distance 1%. With 0% fees, notional = 100 ÷ 0.01 = $10,000. If you post $1,000 margin, leverage ≈ 10x. Net PnL at exit 61,000 uses the same engine as the main calculator.
