How do I calculate position size in forex?

Position size (lots) = (account balance × risk %) ÷ (stop-loss pips × pip value per lot). This keeps every trade to a fixed % of your account.

What's a safe risk per trade?

Most professionals risk 0.5%–2% per trade. Under 1% is common for prop-firm challenges and long-term consistency.

Results assume your account currency matches the pair's quote currency. If different, multiply by the exchange rate between them.

Size every trade to a fixed % of your account — the discipline that separates lasting traders from blown accounts.
