Exchange to Transmit Odd‑Lot Trading Data

The exclusive consolidated data processors (SIPs) will begin disseminating the BOLO and best odd‑lot bid and offer priced at or better than the NBBO in May 2026, and will begin disseminating odd‑lot quotations at each exchange's best odd‑lot bid or offer and the NBBO in May 2028.
