The Mathematical Formula for Position Sizing
Exact breakdown of the variable equation used by professional institutional desks.
Position Size (Lots) = [Account Balance ($) × Risk Percentage (%)] ÷ [Stop Loss Distance (Pips) × Pip Value ($)]
By anchoring your position size to the distance of your stop loss, a trade with a wide 60-pip stop loss risks the exact same dollar amount as a high-precision scalp with an 8-pip stop loss. Your dollar risk remains constant regardless of market volatility.
