Logical Port Fees only when live
The Exchange clarified that monthly Logical Port Fees apply only if the corresponding logical port type is available in the live production environment. The change was filed on January 29, 2026 and is effective immediately, so you will not be charged the monthly Logical Port Fee for a port type until that port type is offered in the live production environment.
Weekend production testing remains free
The Exchange states weekend testing in the production environment is voluntary and logical ports that support a protocol not yet launched in live production will be free during weekend testing until that protocol and port type are available live. Members and non‑Members may use the production weekend testing without being assessed the monthly Logical Port Fee until the port type goes live.
