Pre-Test Requirements

Pre-test participation is optional and on a voluntary basis, but Cboe highly encourages participation during available testing opportunities.

In addition to the aforementioned scheduled pre-tests, Cboe also supports connectivity (telnet) testing to our secondary site ports in Chicago for BYX, BZX, EDGA, EDGX, Cboe Options, C2 Options, and CFE for telnet testing at any time. Secondary site ports are also available for session level connectivity during normal trading hours. Orders submitted during trading hours outside of a DR scenario will result in rejects.
