What does Initial Margin Requirement and Maintenance Requirement mean?

In finance, the initial margin requirement is the amount that must placed in collateral in order to open a position. This requirement can come from regulators, the exchange or the broker.

The amount required to be kept in collateral until the position is closed is called maintenance requirement, and it not necessarily the same amount as the initial margin requirement. Generally, the maintenance requirement is smaller than the initial margin requirement. A maintenance requirement equal to the initial margin requirement is typically only set for especially risky instruments.

What does Margin Call mean?

A margin call is a request (typically from a broker, clearinghouse or exchange) for the holder of a security to add additional funds to cover losses on an outstanding open position.

A margin call is made when the collateral posted in the margin account is less than the minimum margin requirement. The holder of the security can chose between increasing collateral or closing the position. If the holder fails to act, the position can be closed anyway by the broker / clearinghouse / exchange.

The reason behind a margin call is often a change in market value of the asset used as collateral. It can also be caused by an increased margin requirement, e.g. due to legislation or increased volatility.

What does Market On Close (M.O.C.) Order mean?

If you want your order to be executed as close to the end of the market day as possible, you place a Market On Close Order (also known as an at-the-close order).

By placing this type of order, you leave it up to the trader to decide exactly how late in the day the execution will take place.

Many exchanges have rules for how late MOC orders can be submitted. At the New York Stock Exchange MOC orders must be submitted by 15:45, while Nasdaq permits submission of MOC orders until 3:50 EST. After that time, MOC orders can not be submitted, canceled or modified.
