Analyzed Economic Effects

Logical Port Fees Only When Live
The Exchange clarified that monthly Logical Port Fees only apply if the corresponding logical port type is available in the live production environment. This clarification was filed January 29, 2026 and is effective immediately, so you will not be charged for a logical port type that is only available during testing and not yet live.
Weekend Testing Ports Free Until Launch
The Exchange will make logical ports that support an updated or new protocol available for weekend testing in the production environment at no charge until that protocol and corresponding port type are launched in the live production environment. For example, ports supporting a protocol not yet live will be free during designated weekend testing periods until the protocol is available live.
No New Fees — Only Clearer Rules
The filing states that the change does not add any new fees but clarifies when existing Logical Port Fees apply. The Exchange emphasized the change is to reduce confusion about when charges begin, and participation in weekend testing remains voluntary.
