Nasdaq Explains How to Pause Trading in the 23/5 Era

Published Date: 10/16/2026

Notice

Summary

Nasdaq is updating its rules to clearly explain how and when trading in Exchange-Traded Products (ETPs) will pause and restart during its new 23-hour, 5-day trading week. This change affects traders and investors using Nasdaq’s extended hours, making trading smoother and more predictable. The new rules took effect right after filing on October 1, 2026, with no extra costs involved.

Analyzed Economic Effects

2 provisions identified: 2 benefits, 0 costs, 0 mixed.

Newly‑listed ETPs halted at 9:00 p.m.

If an Exchange-Traded Product (ETP) listed on Nasdaq does NOT elect the Initial ETP Open, Nasdaq will halt that ETP at the start of the Night Session at 9:00 p.m. Eastern Time (ET) on its first day of trading. Trading in that ETP will not resume earlier than the start of the Day Session at 4:00 a.m. ET and the Exchange generally expects to open the ETP at 9:00 a.m. ET on the following business day via the Nasdaq Halt Cross.

Issuers can keep the Initial ETP Open

An ETP issuer can elect the Initial ETP Open (under Rule 4120(b)(1)(B)(viii) and (b)(4)(A)(i)d.) so the ETP would be halted from 4:00 a.m. ET and released for trading via the Nasdaq Halt Cross between 9:40 a.m. and 9:45 a.m. ET instead of being subject to the new Night Session halt. Nasdaq carved out ETPs that elect this option so issuers retain the existing Initial ETP Open process.
