Customer Certification and Testing Services

London Stock Exchange Group offers a broad range of reliable and flexible testing services. Developed in-house, our technically advanced services allow our customers to perform various tests against our Trading and Market Data testing services and interfaces.

Customer Development Service

The most comprehensive testing service provided by the Group, Customer Development Service (CDS) is a fully functioning simulation of the Group’s production environment against which our customers can run their Trading and Information applications.

Market activity is determined by the interaction between customers on the service. Our tools ensure that there is background activity in selected market segments, whilst a number of scripted scenarios allow our customers to follow pre-defined marker actions.

There is specialist support available during market hours, should they be required to assist with testing or certification within the environment.

All production market segments are supported on CDS and constituents are regularly aligned with the live service.

CDS sessions can be pre-booked and allow access to the service for a full trading day with extended hours.

For customers that test regularly or appreciate the convenience of uninterrupted access we also offer a Continuous Access Service as a cost effective and efficient means of testing.

Certification Testing Service

A testing service that supports mandatory testing as part of the Group’s software Accreditation policy, our Certification Testing Service has been designed to allow customers to “self” certify their applications. Customers are able to develop and certify their software on our customer development environment, using a single set of enablement details.

Legacy Customer Development Service

The Legacy Customer Development Service (LCDS) provides a scaled down functioning simulation of the Exchange's production environment that uniquely always run current live production software and reference data, thus enabling clients to always have the ability to test and certify any necessary changes they need to make their systems against production version software in line with MiFIDII directives.

LCDS operates and is supported as per the standard Exchange trading hours, reference data will be refreshed on a weekly basis.

A valid Testing Services Agreement is required to be able to access the CDS or LCDS environments.

Live Connectivity Test

Live Connectivity Test allows our customers to test connectivity to the live environment prior to go-live and on any major changes to a customer’s configuration.

Participant Test Weekends

A Participant Test Weekend (PTW) offers our customers the opportunity to test their trading and information systems in the production environment.

The service is designed for instances where performance is the main driver for customer testing or if customers wish to test their own disaster recovery or other business continuity scenarios.

PTW sessions can be pre-booked and scheduled on a regular basis throughout the year. Each PTW provides access during a Saturday for a shortened trading day.
