What this tells you

Margin is not a fee — it is the slice of your balance the broker reserves so the position can exist.

Method

Notional = lots × contract size × price. Required margin = notional ÷ leverage. Free margin = balance − used margin, and margin level = equity ÷ used margin × 100. Leverage and stop-out level come from the values you enter, which must match your broker.

Where the numbers come from

Contract sizes, pip conventions and session hours come from one published specification table, and the same class answers on the page and through the API. A conversion rate is only ever the figure you enter — the site does not fetch a price, because a hardcoded quote would be wrong for your broker and stale in seconds.

Which leverage should I enter?

Your own account's leverage. It differs by jurisdiction and by instrument, so there is no single correct number we could assume for you.
