Nasdaq Sets May 14 Launch for New Post-Trade Risk APIs

Nasdaq said it will launch new REST APIs for its Post Trade Risk service on 14 May 2026, expanding access beyond the existing WorkX interface. In an April 30 Equity Trader Alert, the exchange said the APIs will allow clearing firms, executing brokers, correspondent firms, and eligible counterparties to monitor limit settings and real-time risk levels programmatically across Nasdaq exchanges, RASH, and the FINRA/Nasdaq TRFs.

The new API layer will cover two live functions at launch: limit settings and risk monitoring. Nasdaq said clearing firms will be able to create or modify limit settings by API, while counterparties will be able to see real-time risk levels against established limits where access is permitted. The service itself will be free for PTR-enabled TRF participants, although standard WorkX fees still apply for firms using the separate WorkX front end.

Nasdaq also signaled a later API expansion for trade actions, including access to held and killed trades and the ability for clearing firms to action held trades electronically. That follow-up is not live yet, but it shows where the workflow is heading: less manual screen-based oversight and more direct integration into broker risk infrastructure.

Why it matters

For traders and broker desks, post-trade controls increasingly shape how quickly issues are spotted and how efficiently limits are managed. API-based access can make risk oversight more continuous and easier to connect with internal monitoring tools instead of relying on a separate UI.

What to watch next

Watch for the 14 May production launch, testing uptake through Nasdaq’s test facility, and any later trader alert covering the promised trade-action APIs.
