MIAX Futures Exchange - Onyx Trading Platform - Financial Futures - Reminder: Final Confidence Test and Launch on May 17, 2026

As previously announced in the April 29, 2026 and May 11, 2026 Alerts, MIAX Futures will introduce functionality to support trading of financial futures products on the MIAX Futures Onyx trading platform on Sunday, May 17, 2026 for the Monday, May 18, 2026 trade date. The MIAX Futures Financials Market Identifier Code (MIC) is XMFE. Financial futures products will trade in the NY5 data center.

The Final Confidence Test will take place this Saturday, May 16, 2026 from 8:00 a.m. to 1:00 p.m. ET.

Pre-Production Readiness Verification:

  1. For pre-production readiness verification, network and application layer connectivity testing to the MIAX Futures production environment is available during trading hours by request between now and Friday, May 15, 2026. Please contact  MIAXfuturestradingoperations@MIAXGlobal.com to arrange for testing.
  2. Connectivity to the FOI, FEI and the FIX Drop interfaces will be provided via production credentials. The entering of test orders, among other supported message types, will be supported.
  3. The dissemination of data across production ToM and DoM multicast feeds will be supported during the testing period. Firms enabled to read the market data feeds may receive test data during the testing period.
  4. Firms intending to utilize the pre-production readiness period for production connectivity testing MUST take necessary steps to avoid unintended data leakage into their production systems. Firms MUST insulate their own production systems from this test data activity as needed. If this is not possible, firms MUST avoid establishing production connectivity during this time. Firms using an extranet provider may need to work with them directly to avoid receipt of the multicast data feeds during this period if that is the intent.
