TSX Alpha Minimum Interaction, Quantity

Published on: Apr 8, 2025

On Apr. 3, TSX Alpha proposed amendments to order size features.

  • TSX Alpha proposed changes to minimum interaction size, minimum quantity features.
  • Proposed Amendments
  • Amends the functionality of the minimum interaction size (MIS) and minimum quantity (MinQty) features to meet the diverse needs of market participants, trading strategies.
  • When MinQty order’s remaining size falls below MinQty thresholds, remaining volume of the MinQty order will be permitted to trade in any board lot amount by default.
  • Participants may opt out of using default current functionality and instead choose to have the order canceled when MIS, MinQty order's remaining size fall below threshold.
  • Modifies current MIS eligibility to consider the remaining tradeable volume of an incoming contra-side order, instead of entered size of an incoming contra-side order.
  • Will enhance the overall effectiveness and predictability of trade executions, as participants would be able to decide what they want to allow on order by order basis.
  • By offering flexibility, participants can retain autonomy, gain greater precision, over how orders are handled, by ensuring all trade executions align with initial conditions.
  • Consultation
  • Written comments on proposed amendments due by May 5, 2025.
