Moomoo announced the launch of extended US equity-options trading on 19 October, giving customers access to Cboe’s new sessions from their first day. The initial offer covers options on 25 stocks and five ETFs. Securities are offered through Moomoo Financial Inc.; access depends on the customer’s eligibility and options approval level.[1]
Published session windows
| Session | US Eastern Time |
|---|---|
| Premarket | 07:30–09:25 |
| Regular single-stock session | 09:30–16:00 |
| Post-close curb | 16:00–16:15 |
The broker’s operating guide specifies limit orders in the extended sessions: market, stop and stop-limit orders are unavailable. Good-till-cancelled and good-till-date instructions may persist across sessions according to their session designation. Inclusion of a stock in the programme does not guarantee that every strike and expiry is open; the order ticket identifies the available session.[2]
That changes how an existing trading plan carries into the extra window. A customer relying on a stop order during ordinary hours cannot assume the same instruction will provide protection in the curb session. The 15-minute post-close window also ends before an announcement released at 16:20; access still depends on when the news arrives.[2]
Moomoo cautions that extended sessions can have wider spreads, lower liquidity and greater execution uncertainty. The launch gives customers another opportunity to adjust eligible positions around news, while the price and quantity available on the order book determine whether that opportunity is usable.[1]
