Futures

As previously announced in the May 27, 2025 Alert, MIAX Futures is preparing for the migration of Minneapolis Hard Red Spring Wheat Futures from CME Globex to the new MIAX Futures Onyx Trading Platform on Sunday, June 29, 2025 (Trade Date: June 30, 2025).

Pre-Production Readiness Verification:
 

1. For pre-production readiness verification, network and application layer connectivity testing to the MIAX Futures production environment will be available during trading hours by request between Monday, June 16, 2025 and Friday, June 27, 2025. 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. As a precaution, trading in HRSW products will be halted immediately upon system startup. The trading halt will disable trading in HRSW but will allow other message traffic to be supported during the testing period.
5. During the testing period, MIAX Futures will use a test product (“TST”), that will be used to simulate trading during the testing period. Please refer to the attached documentation for additional Test Symbol details.
6. Firms may receive market data and trade messages for TST across the market data feeds. Firms may use TST for testing purposes while interacting with the FOI, FEI and FIX drop interfaces.
7. 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.

Testing Dates:

1. Industry Testing is scheduled between 8:00 a.m. - 12:00 p.m. EDT on the following dates:
   1. Mock Trading Industry Test #3: Saturday, June 14, 2025
   2. Final Confidence Test: Saturday, June 28, 2025
