- Margin Call
A call from a broker or firm to a customer, to bring margin deposits up to a required minimum level. Exchange rules state that margin calls must be satisfied by bringing your account equity back to the Initial Margin level. Failure to meet a margin call immediately may result in some or all of the trader’s positions being liquidated by the firm without prior notification.
