Terms of use.

Last updated: July 2026

Introduction

These Terms of Use govern your access to and use of the mmsys.xyz website (the "Site"), operated by ModernMarkets. By using the Site, you agree to these terms. If you do not agree, please do not use the Site.

About ModernMarkets

ModernMarkets is a technology vendor. We design and support FIX protocol connectivity software and related managed infrastructure services for brokerages and other institutional counterparties. ModernMarkets is not a broker-dealer, exchange, investment adviser, or other regulated financial-services firm, and nothing on this Site should be read to suggest otherwise. Our services are made available exclusively to institutional counterparties, and only under a separate written services agreement negotiated directly with the customer. No services are offered to retail consumers through this Site.

Informational purpose only

This Site is provided for general informational purposes about ModernMarkets and its technology offerings. Nothing on the Site constitutes an offer to sell, a solicitation of an offer to buy, or a recommendation regarding any product, service, security, or financial instrument. Nothing on the Site constitutes investment, financial, legal, tax, or trading advice. Any description of our technology, its capabilities, or performance characteristics is general and illustrative; binding commitments, if any, exist only in a signed services agreement.

Intellectual property

All content on this Site, including text, graphics, logos, and design elements, is owned by ModernMarkets or its licensors and is protected by applicable intellectual property laws. You may view and reference this content for your own informational purposes, but you may not copy, reproduce, distribute, or create derivative works from it without our prior written consent.

Acceptable use

You agree to use the Site only for lawful purposes. You may not attempt to interfere with the Site's operation, probe or scan its infrastructure without authorization, submit false or misleading information through any form on the Site, or use the Site to transmit harmful code.

No warranty; limitation of liability

The Site and its content are provided "as is" without warranties of any kind, express or implied, including as to accuracy, completeness, or fitness for a particular purpose. To the fullest extent permitted by law, ModernMarkets disclaims liability for any loss or damage arising from your use of, or inability to use, the Site or its content. This limitation applies only to use of the Site itself; it does not govern any services provided under a separate services agreement, which is governed by its own terms.

Services governed separately

Any actual technology or managed services provided by ModernMarkets are governed exclusively by the terms of a separate, mutually executed services agreement between ModernMarkets and the institutional customer. These Website Terms of Use do not create, amend, or supersede any such agreement.

Changes to these terms

We may update these Terms of Use from time to time. The "Last updated" date above reflects the most recent revision. Continued use of the Site after changes are posted constitutes acceptance of the revised terms.
