Order Routing System


The ISE Order Routing System serves as a front-end for the OTS, which allows Electronic Access Members to submit orders to and receive execution reports from ISE in their preferred message formats and communications protocols.

ISE’s Order Routing System software is supplied by GL TRADE Americas.

Scalable Configuration

ISE’s Order Routing System operates on redundant pairs of servers. Each pair of servers handles a subset of ISE’s order routing members. As new order routing firms connect to ISE, additional servers can be installed as necessary.

Full Redundancy

The hardware, software and network components in the Order Routing System are fully redundant and operate in a distributed environment across geographically diverse sites. The system is designed to recover quickly from any single point of failure.
