Margin

Margin is eligible collateral or account value required to open and maintain leveraged exposure rather than the full economic value of the position.

Margin supports potential obligations arising from a position and is recalculated as prices, positions, and account equity change. It should not be confused with a fee or with the maximum possible loss, because the account remains exposed to the position’s notional movement. Initial, maintenance, and platform-specific risk requirements can differ, and reserved margin is generally unavailable for other uses elsewhere in the account.
