Market Access

Once firms have made the decision to access TMX markets as a Participating Organization or through Direct Market Access, there are a variety of ways to electronically access TMX markets depending on your needs and objectives.

  • Certified Access Providers

    Access Vendors

    Access Vendors are firms that provide comprehensive technology solutions and network access to TMX order-entry gateways and market data feeds.

    Application Vendors

    Application Vendors are firms that provide the application level for integrated technology platforms, including OMS/EMS solutions.

  • Session Bundle Setup & Certification

    Once access is established at the network level, order entry application access (via session bundles) is configured and managed through the TMX Market Operations group both for the production and the testing environment. Each order entry session provides secure access for individual clients to send and receive order entry and confirmation messages between the clients' systems and TMX gateways and matching engines. Certification in the testing environment is required for all new customers, and if needed, for existing customers prior to scheduled upgrades.

    Gateway Test Environment ("GTE")

    The GTE environment is a functional test environment which mimics the functionality of the Production environment. Users may use GTE for application certification, User Acceptance Testing, or other required functional testing. Performance or load testing is not permitted.

    New functionality and code changes are deployed in GTE prior to Production, in order to provide users an opportunity to test future functionality in advance of Production go-live.

    The GTE environment is available for order entry as well as some market data feeds. Content on GTE market data feeds is generated by GTE order entry activity.

    For information regarding GTE connectivity, order entry session bundles, market data feeds or general inquiries, contact TSX Market Operations at or 416-947-4705.
