FINRA Flags NSCC Trade-Processing Requirements for 24x5 Trading

FINRA published a technical notice on 14 August alerting members that use FINRA Trade Reporting Facilities to clear trades about new NSCC requirements connected to 24x5 trading.

The notice says FINRA’s TRFs are expected to extend operating hours to support 23x5 trade reporting from 6 December 2026, with a one-hour technical pause each weeknight at 8 p.m. Eastern Time. FINRA said DTCC’s NSCC subsidiary expanded its operating hours on 28 June 2026 to support 24x5 trading.

The practical issue is relationship management for overnight clearing. FINRA said NSCC will require separate 9A/9B trading relationships for the overnight session for Correspondent Clearing and Qualified Special Representative relationships. Those relationships can be established through NSCC’s Automated Special Representative Facility.

FINRA stressed that the relationship requirement is an NSCC requirement rather than a FINRA requirement. It also said it will not require firms to update Uniform Reporting Agreements for overnight trade reporting, but warned that trades could be accepted by a TRF and then rejected at NSCC if the overnight clearing relationship is not in place.

Why it matters

For brokers and active equity traders, extended-hours access depends on more than the front-end order ticket. Clearing, trade reporting and locked-in agreement setup all need to work during the overnight session.

If a broker is not operationally ready, traders may see rejected trades, narrower overnight access or limits on which accounts and order flows can use near-continuous U.S. equity trading.

What to watch next

Watch broker notices before the December TRF schedule change. The key details are which venues and account types support overnight trading, whether clearing arrangements are complete, and how firms handle risk controls around the nightly technical pause.
