How Position Size Calculators Work
A position size calculator determines the number of lots (or units) to trade based on three inputs: your account balance, your risk percentage, and your stop loss distance. The formula is:
Each instrument has a different pip value. EUR/USD has a pip value of $10 per standard lot per pip. USD/JPY pip values vary with the exchange rate. Gold (XAU/USD) is $10 per pip but each pip is $0.10 — so a $1 move equals $100 per lot. Our calculators handle all of this automatically.
Professional traders and FTMO-funded accounts typically risk 0.5%–1% per trade. This allows recovery from losing streaks while keeping position sizes large enough to generate meaningful returns.
