The single biggest difference between traders who survive and those who blow up is position sizing. Here is how to do it properly.
The formula
لوتات = (رصيد الحساب × المخاطر%) ÷ (Stop-loss in pips × Pip value per lot).
A worked example
الحساب: $5,000. المخاطر: 1% = $50. وقف الخسارة: 25 pips on EUR/USD, where one standard-lot pip ≈ $10. لكل لوت stop cost = 25 × $10 = $250. لوتات = 50 ÷ 250 = 0.20 لوتات.
Why fixed-percentage risk works
متى أنت always risk the same small percentage, no single trade can seriously damage your حساب, and your dollar risk stays steady whether your stop is tight or wide. This is the mechanical foundation of طويلة-term survival.
