Understanding Position Sizing in Forex

Many new traders focus solely on entry/exit points, neglecting the critical role of position sizing. It's not about how often you're right, but how much you risk when you're wrong. A common approach is to risk a fixed percentage of your total account balance per trade, say 1-2%. If your account is $10,000, risking 1% means you're willing to lose $100 on that specific trade. Now, relate this to your stop-loss distance. If your stop for a $USDZAR long is 50 pips, and each pip is worth $10 for a standard lot, you'd be risking $500 per lot. To stick to your $100 risk, you'd only trade 0.2 lots. This prevents any single loss from being catastrophic and ensures long-term viability, even with a moderate win rate. It's the most effective defense against blowing up your account.
