Additional margin
Collateral furnished by holders of options or non-spread futures contracts to cover the potential costs of closing out their positions.
The additional margin covers the losses that would result from the worst-possible price development (worst-case loss) during the following 24-hour period. The margin is paid to the central clearinghouse by the contract holder.
