Gold and Index Position Size Calculator
Size a CFD using the exact tick size and loss tick value from your broker. Generic gold and index contract assumptions can produce the wrong volume.
Use the actual symbol specification
Loss per lot = absolute entry-to-stop distance ÷ tick size × loss tick value, plus entered commissions and extra price-tick costs. Risk budget is equity × risk percentage. Volume is rounded down to the lot step and capped by the maximum. The minimum is never forced when it would exceed the budget.
The inputs are an illustrative contract, not a claim about a particular XAUUSD or index CFD. A broker may use a different contract size, lot minimum or point value. Copy tick size, tick value and volume limits from that broker’s exact symbol and verify a one-lot hypothetical loss using the platform.
Limits of the estimate
Tick values may change with currency conversion or instrument price. Use a loss tick value in account currency appropriate to the planned exit. This constant-tick estimate does not model nonlinear products, futures expiry adjustments, guaranteed-stop premiums or a margin close-out. Standard stops can slip.
Frequently asked questions
Why not assume that one gold lot is always 100 ounces?
Brokers and instruments can use different contracts. This calculator uses the loss tick value and tick size from your own symbol specification rather than a fixed gold or index contract.
Where do I find the inputs in MT5?
Open the symbol’s Specification from Market Watch. Check tick size, tick value, minimum volume and volume step. Confirm the loss tick value is expressed in your account currency.
