One-minute intra-day options data for buyers
MIAX introduced a new One-Minute Interval Intra-Day Open-Close Report that produces data snapshots every one minute during the trading day and will be available to purchase by Exchange Members and non-Members. Subscribers would receive each one-minute snapshot within about five minutes after the interval (the Exchange expects delivery to range from 2–5 minutes after each one-minute snapshot); the first example delivery would be approximately 9:34 a.m. ET for data captured from 9:30–9:31 a.m. The report provides the same option-level fields as the existing intra-day product (by origin, buy/sell, open/close, and trade-size buckets) but at one-minute intervals, and the Exchange intends to file fees for the product in a separate rule filing.
