💡 FX Risk Management Insights

📐 How Lot Size is Calculated

Lot size = Risk Amount ÷ (Stop Pips × Pip Value per Lot). The pip value depends on your pair's quote currency and is converted to your account currency using live FX rates. Always verify pip value for exotic pairs or metals.

Gold (XAUUSD): pip = $0.01, lot size = 100 oz. 1 pip per lot = $10.

🔵 Why Fusion Markets?

Fusion Markets charges $4.50 per standard lot round trip — one of the lowest ECN commissions globally. IC Markets charges $7.00 and IG charges variable spreads often exceeding $10/lot. On high-volume trading, the difference compounds to thousands per year.

⚖️ Commission as % of Risk

If your commission exceeds 15% of your risk capital on a single trade, your statistical edge is being significantly eroded. Reduce position size, widen your stop, or switch to a lower-commission broker to protect your edge.

Target: commission < 10% of risk per trade for a healthy risk model.
