Margin Call

When the margin posted in the margin account is below the minimum margin requirement, the broker or exchange issues a margin call. The investor now either has to increase the margin that he has deposited, or he can close out his position. He can do this by selling the securities, options, or futures if he is long; and by buying them back if he is short.
