NYSE Texas Extends Trade Clock to 2030: Yawn-Worthy Update
Published Date: 9/15/2025
Notice
Summary
NYSE Texas 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 system, giving them more time before stricter timing rules kick in. The update is effective immediately, so everyone can plan ahead without any surprise costs.
Analyzed Economic Effects
2 provisions identified: 2 benefits, 0 costs, 0 mixed.
Timestamp Exemption Extended to 2030
If your firm submits trade data to the Consolidated Audit Trail (CAT), the rule now says you must truncate timestamps to the nanosecond level for submission until April 8, 2030. The Exchange replaced the previous expiration date of April 8, 2025 with April 8, 2030, so the truncation (not rounding) requirement continues through that date.
Amendment Became Operative Immediately
The Exchange's amendment became operative upon filing (filed August 27, 2025) after the SEC waived the usual 30-day delay. This immediate effectiveness lets Industry Members plan now for the extended April 8, 2030 timestamp rule without facing surprise compliance costs when the rule becomes operative.
