Formula & Mathematical Methodology: Position Sizing Financial Formula

RiskAmount = Account × RiskPct
Shares = RiskAmount / |Entry − StopLoss|
RiskAmount = Account × RiskPct; Shares = RiskAmount / |Entry − StopLoss|
  • accountEquity: Account Equity (currency)
  • maxRiskPct: Max Risk Pct (%)
  • entryPrice: Entry Price (currency)
  • stopLossPrice: Stop Loss Price (currency)
  • targetPrice: Target Price (currency)

Rounding: Internal compounding uses full floating-point precision; currency outputs round to 2 decimal places.
