Trading rules: order and off order book


Off order book trading rules

The order book trading rules are aligned closely with the operation and system rules of the trading system.  In general the order book trading rules are high level and reference the trading system and parameters where applicable.

They are designed to be resilient to system configuration changes at segment and sector level within the trading system.

The rules primarily cover how member firms access the trading system and the responsibilities of member firms for their order management.  These include order routing and member authorised connections.  They also cover contra requests and the reversal of erroneous trades.

Off order book trading rules

The off order book trading rules are less reliant on the system rules of the trading system and govern how member firms must interact when trading on Exchange away from the order book.

This section of the rules is more extensive than the order book trading rules and covers subjects such as the determination of an on Exchange trade, trade reporting, trade publication, and obligations of member firms to market makers.
