FAQ
How do I calculate position size in forex?
Position size = (Account balance × Risk %) ÷ (Stop loss in pips × Pip value). A $10,000 account with 1% risk and 20 pip stop on EUR/USD = $100 ÷ $200 = 0.5 lots.
What percentage of my account should I risk per trade?
Professional traders typically risk 1-2% per trade. Beginners should start at 0.5-1% until they have a proven edge.
