Amendment Of EMS Subscriber Agreement Related To Your Use Of The Eze EMS (Formerly Realtick EMS)

Effective as of December 1, 2017, the EMS Subscriber Agreement (and its equivalent forms) that you or your firm (“You” or “Customer”) have signed will be amended to add new terms which will apply to your use of the Eze EMS. Highlights of the changes are provided below and the full text of the new terms are provided in the "December 1, 2017 EMS Subscriber Agreement Updated Terms” document.


  • Following a corporate restructuring that occurred on October 1, 2015, Eze Castle Software LLC (“Eze Software”) operates the Eze EMS business that was previously operated by RealTick LLC (formerly known as Townsend Analytics, Ltd.).

  • The Eze EMS is provided via a service based model to You by Eze Software. All licensing oriented terms in the EMS Subscriber Agreement have been replaced with corresponding service oriented terms.

  • Eze Software will not seek to collect fees from You which are incurred by broker-dealers for any services provided to such broker-dealers, including, but not limited to, FIX connections or fees related to any order flow that You may submit to any execution destinations via the Eze EMS. You are only responsible for the fees arising from your use of the Eze EMS service. You are still responsible for payment of all other fees that You incur by using the Eze EMS as stated in your EMS Subscriber Agreement and Order Form if You or your Billing Party fails to pay any amounts when due. This is a clarification of third party billing aspect of the EMS Subscriber Agreement and it will not change your use of or fees associated with the Eze EMS.
