Limit order

A limit order is a buy or sell order with a specified price limit, where buy orders can be executed at the limit price or lower and sell orders can be executed at the limit price or higher. Limit orders may be partially executed.

User-defined block order

A block order consisting of one or several (up to 24) consecutive hourly products. User-defined block orders are all-or-nothing orders where only the entire volume may be executed.

Predefined block order

UK-specific block orders.

Iceberg order (IBO)

A type of limit order, usually with a large volume, with the purpose of hiding the full size of the order by dividing it into smaller clips. The first clip is shown to the market and the next clips will be visible when the previous ones have been fully matched. New clips receive a new time stamp.

Execution constraints

-Fill-or-Kill (FoK)

A limit order where the entire volume of the order will be either matched immediately upon submission or withdrawn from the market.

-Immediate-or-Cancel (IoC)

A limit order where as much as possible of order volume is matched immediately upon submission and remaining volume is withdrawn from the market.
