MIAX (formerly MGEX) will begin handling futures and options order routing and data dissemination using their own proprietary platform starting on June 30th, 2025. This will result in a change in price quotation from cents to whole dollars. Futures and options prices in decimal formatted client daily files will be smaller by a factor of 100.
