TSX Alpha Exchange Receives Regulatory Approval Regarding its Static Order Processing Delay

TMX Equities is pleased to announce that it has received regulatory approval regarding its proposed static order processing delay ("Static Order Processing Delay") on TSX Alpha Exchange ("Alpha"), as described in Equities Notice 2023-017 and 2023-021.

The Static Order Processing Delay is being updated to statically hold all messages for 1 millisecond instead of dynamically randomizing between 1-3 milliseconds as Alpha currently does today. Orders marked as post only which meet the minimum size requirements will continue to bypass the delay.

The Static Order Processing Delay will be implemented on July 17, 2023.
