Maintenance Margin×

A sum usually smaller than, but part of, the original margin (security deposit) that must be maintained on deposit at all times. If your account falls below the maintenance margin requirement, you will receive a margin call. If you wish to continue to hold the position, you will be required to restore your account to the full initial margin level (not to the maintenance margin level). See Margin.
