Executive Summary

The SEC has published NYSE American’s notice of filing and immediate effectiveness for a proposed rule change introducing a new One-Minute Interval Intra-Day Report, a version of the NYSE Options Open-Close Volume Summary. The new report will be available to all subscribers and will provide the same data categories as the current Intra-Day Volume Summary, but snapshots will be taken every one minute during the trading day instead of every ten minutes. NYSE American states that each one-minute update will be available within five minutes after the relevant one-minute period and will contain proprietary Exchange trade data only, not consolidated options market data. The product is voluntary and does not impose a mandatory reporting obligation on members or market participants. The Exchange will file a separate proposed rule change to establish monthly subscriber fees before launch and will announce the implementation date by Trader Update, with implementation no later than the end of the fourth quarter of 2026, subject to effectiveness.
