Pre-Testing

To facilitate readiness for the formal testing on October 24, 2026, Cboe in coordination with other market centers, as part of the annual SIFMA/FIA industry test and in support of Reg SCI requirements, will facilitate two pre-tests from the Chicago (Secondary) site. The September 26, 2026 pre-test will allow connectivity testing only, while the October 10, 2026 pre-test will involve a failover from Secaucus (Primary) to Chicago (Secondary) site like the formal test does.
