TMX Equity Trading Notice

Alpha-X™ and Alpha DRK™ Books Webpage and Specification Details

Further to Equities Trading Notice 2023-006, TMX Equities is pleased to provide specification details related to the proposed implementation of the Alpha-X and Alpha DRK books (subject to regulatory approval). We are also announcing the launch of a new Alpha-X and Alpha DRK webpage, which includes an FAQ on the new order books, and where we intend to provide further implementation details as we move closer to the launch date.

The new Alpha-X and Alpha DRK order books aim to provide a democratized trading environment, with focus on innovation and execution quality. Innovative new order types, together with an order processing delay, are expected to afford the natural investor a high-quality trading experience, with protections against adverse selection.

The order books are expected to be launched in September 2023 (subject to regulatory approval), with GTE availability in June 2023.
