The Lot Size Formula
Lot Size = (Account Balance × Risk %) / (Stop Loss in Pips × Pip Value)
Pip Value depends on the currency pair and contract size. For most forex pairs (e.g. EUR/USD), 1 pip = 0.0001, and a standard lot (100,000 units) has a pip value of $10.
Example: With a $10,000 balance, 2% risk, and 50-pip stop loss on EUR/USD: Lot Size = ($10,000 × 0.02) / (50 × $10) = 0.40 lots.
