U.S. Options

The MIAX Options Exchange will introduce modifications to the following functionality beginning Monday, October 9, 2017.

Opening 

• MIAX is modifying the Opening to enhance the speed of the opening. In a given class, once all opening requirements are met, the Exchange will open all options in the class which do not have any locking or crossing events. Once all of those options are open, the Exchange will open the remaining options, using the current methodology. There is no direct impact on Members.

Complex Order Pricing

• MIAX is modifying the methodology used to determine the individual component prices resulting from the net price of a complex trade.  The change is being made to optimize the component prices to the prevailing market.

Rollout Schedule

• October 9, 2017: All options associated with underlying symbols starting with the letter Z (Match Engine 21) 
• October 10, 2017: All options associated with the underlying symbols starting with the letters U-Y (Match Engines 18-20) 
• October 11, 2017: All options associated with the underlying symbols starting with the letters A-L (Match Engines 1-11, 22-23)
• October 12, 2017: All options associated with all remaining underlying symbols (Match Engines 12-17, 24)

All interface specifications are currently available at MIAX Options Interface Specifications.

The above updates are currently available in the MIAX Firm Test Bed #2 (FTB2) environment.
