Nasdaq Testing Facility (NTF)

Customers are reminded that the fee-based Nasdaq Testing Facility (NTF) allows firms to test their automated systems that integrate with Nasdaq’s services. The NTF service supplies firms with a venue to test upcoming Nasdaq releases and product enhancements. In addition, firms may use the NTF to test their new software development prior to implementation. The NTF operates weekdays, Monday through Friday, 7:00 a.m. to 11:50 p.m., ET.

Additionally, product specific User Acceptance Tests (UATs) will continue to be scheduled in addition to the predetermined Saturday general customer testing dates. Nasdaq market participants can subscribe for new connectivity or update an existing service by completing the Nasdaq Port Request Form and faxing it to Nasdaq Subscriber Services at +1 212 231 5426.
