System Changes to Be Validated

Testing of the New Network
We are continuing Phase 2 of the project, now for the Binary Order Entry of Equities and Derivatives as planned and previously announced.
Additionally, as part of the validation process for the new network, there will be a special opportunity for additional testing this Saturday, October 11. On this day, users will be able to connect to the new network to access the binary Order Entry and Market Data systems. This is an excellent chance for all involved to experience the functionalities of the new infrastructure and validate their connections. We encourage all users to take advantage of this opportunity to validate the connection of the new network and identify any unexpected aspects in their systems.
