Frequently Asked Questions
How much should I risk per trade?
Professional traders typically risk 1–2% of their account per trade. This means even 10 consecutive losses only reduce your account by 10–20%.
How is position size calculated?
Position Size = (Account × Risk%) / Stop Loss Distance%. For example: $10,000 account, 1% risk, 5% SL → $100/$0.05 = $2,000 position.
