Frequently Asked Questions
How do I calculate forex position size?
Position Size = (Account Balance × Risk%) ÷ (Stop Loss in pips × Pip Value per lot). Example: $10,000 account, 1% risk, 20-pip stop on EURUSD = $100 ÷ (20 × $10) = 0.50 lots.
What percentage should I risk per trade?
Most professional traders risk 1–2% of account equity per trade. Risking a small fixed percentage ensures a losing streak cannot wipe out the account.
What lot size for a $1000 account?
With $1,000, risking 1% ($10) on a 20-pip EURUSD stop = $10 ÷ (20 × $10) = 0.05 lots (a micro-lot position). Keep leverage and risk low on small accounts.
