TMX Equities QuantumFeed Services (QFS) – Stream ID Expansion

TMX Market Operations would like to inform clients of upcoming changes to the TSX QuantumFeed Service ("QFS").

To support system capacity and optimize data delivery across TMX equities marketplaces, additional Stream IDs have been introduced across TSX, TSXV, TSX Alpha Exchange, and TSX Alpha X/DRK feeds. Effective Monday, October 5th, 2026, production symbols will be allocated to the new Stream IDs.

Recipients of the QFS binary feeds should ensure their system configurations are updated by October 5th to accommodate the expanded stream ranges. Test symbols are currently available in the new Stream IDs for validation purposes.

The updated QuantumFeed Service Access Guide is available on the TMX Webstore.
