NYSE National Extends Trade Deadline—More Time, Same Grind
Published Date: 9/12/2025
Notice
Summary
NYSE National is updating a rule about how it tracks trade times to match a new exemption that extends the deadline from 2025 to 2030. This change affects traders and firms using the Exchange’s systems, giving them more time before stricter timing rules kick in. The update is effective immediately and won’t cost anyone extra right now.
Analyzed Economic Effects
2 provisions identified: 2 benefits, 0 costs, 0 mixed.
Timestamp Truncation Exemption Extended
If your firm is an Industry Member that captures timestamps finer than nanoseconds, you must continue truncating timestamps after the nanosecond level (not rounding) when submitting data to the Consolidated Audit Trail (CAT) until April 8, 2030. The Exchange amended Rule 6.6860(a)(2) to replace the prior expiration date of April 8, 2025 with April 8, 2030.
Amendment Effective Immediately Upon Filing
The Exchange filed the proposed rule change on August 27, 2025 and the Commission designated the proposal to be operative upon filing, so the amendment reflecting the April 8, 2030 expiration is effective immediately. The Exchange requested a waiver of the normal 30-day operative delay and the Commission granted that waiver.
