Cboe Options has made immediately effective a fee-credit program for redundant logical ports created during an exchange-initiated protocol migration, such as BOEv2 to BOEv3. To receive the credit, a TPH must designate the port to the Trade Desk, cancel it within 30 calendar days, request the credit within 30 days after cancellation—and send orders or quotes through it only when an exchange migration problem prevents use of the new port. Cboe will inspect actual usage before crediting a later invoice. Member-initiated changes such as FIX-to-BOE do not qualify. SEC notice, September 1
Treat the redundant session as a break-glass route, not ordinary active-active capacity: explicit enablement, usage alarms, evidence retention, a decommission date and invoice reconciliation. One enthusiastic production test can turn the “free” port into a small lesson in why fee schedules belong in operational requirements.
