📖 Factor breakdown & global trading standards (incl. USA)
📌 Risk % per tradeRecommended 1-3% per trade by most regulators. In the USA, pattern day trading rules for forex still enforce reasonable risk management. Global retail traders use fixed fractional risk.
📊 Stop Loss (pips)Distance from entry to stop. US brokers require FIFO but stop loss is crucial for defining risk. Worldwide, ATR-based stops are standard.
💱 Pip ValueValue per pip movement per standard lot (100k units). Accurate conversion respects pair & account currency. For US traders, pip value affects margin & tax reporting.
⚡ LeverageUS maximum retail leverage is 1:50 for major pairs (NFA/CFTC). EU/ESMA restricts to 1:30, other regions up to 1:1000. Our calculator adapts to your local leverage.
🧾 Margin RequirementFunds needed to open position. Based on lot size, pair price, leverage. US brokers impose minimum margin rules; always monitor usage.
🌍 Cross-currency conversionSupports any account currency (EUR, GBP, JPY, etc). Uses reference USD rates for accurate pip conversion—suitable for global traders.
✨ All calculations follow forex industry standards: 1 standard lot = 100,000 units, pip size = 0.0001 for most pairs, 0.01 for JPY pairs & Gold (XAUUSD: 0.01 pip step = $0.01 per unit for gold but here we treat with standard 0.01 increment per pip for simplicity). The advanced algorithm ensures correct position sizing worldwide.
