Why position sizing matters
Consistent position sizing is what separates traders who last from those who blow up. By risking a fixed small percentage of your account per trade, no single loss can take you out of the game.
The formula
Amount at risk = balance × risk%. Position size (lots) = amount at risk ÷ (stop-loss in pips × pip value per lot). Most traders risk 0.5–2% per trade.
