Why Position Sizing Matters
Position sizing is arguably the most important skill in trading. Even with a 50% win rate strategy, poor position sizing can wipe out your account, while correct sizing can make it highly profitable. The general rule used by professional traders is to never risk more than 1–2% of your total account balance on a single trade.
This calculator uses the standard formula: Position Size = (Account Balance × Risk%) ÷ (Stop Loss in Pips × Pip Value). It gives you the exact lot size to trade so your maximum loss on any single trade never exceeds your predefined risk amount.
