Extended Hours Are Coming to OPRA Options Data

Jul 23, 2026

TL;DR: Starting August 17, 2026, Cboe's Options Exchange is extending trading hours for select single-stock equity options with a morning GTH session (7:30–9:25 am ET) and Curb session (4:00–4:15 pm ET). All activity routes over existing OPRA RTH feeds, so Massive customers get the extended data seamlessly, with zero code changes required.

What's changing

Cboe is adding two sessions on either side of the regular trading day for a set of high-liquidity equity options. Effective August 17, 2026, the schedule for eligible classes looks like this:

SessionTime (ET)
Pre-opening Queuing7:15 am
Global Trading Hours (GTH)7:30 am – 9:25 am
Regular Trading Hours (RTH)9:30 am – 4:00 pm
Curb Trading Hours4:00 pm – 4:15 pm

There are no sessions on market holidays. Quoting and trading activity in these sessions will be disseminated over the existing OPRA RTH channels, which is why it will land in Massive's options feeds alongside the regular session with no changes required on your end.

Which options are eligible

Cboe designates the eligible equity option classes based on its own criteria, targeting the most actively traded and liquid names.

Anticipated initial list:

AAPL AMD AMZN AVGO BABA GOOG GOOGL HOOD INTC META MSFT MU NFLX NVDA ORCL PLTR TSLA

What it means for your data

More session time means more options activity to capture, analyze, and act on. The practical effects for data users:

  • Pre-market and post-close quotes and trades for these symbols will now appear directly in your existing trades and quotes streams, extending the daily window of available options activity.
  • Backtests and intraday models that assume a 9:30 am–4:00 pm options session for these names should account for the wider window.
  • Event-driven strategies around earnings and overnight macro releases can reference options activity closer to the news, rather than waiting for the RTH open.
  • The daily bar represents the official regular-session summary, so its OHLC, volume, VWAP, and transaction counts stay based on regular hours and are unaffected by the extended sessions. All shorter aggregate timeframes include the extended sessions, as do the Trades and Quotes endpoints and the pre-market and after-hours fields of the Daily Summary API.
