Market Hours and Extended-Hours orders

Last updated: October 23, 2026

Clear Street supports four U.S. equity trading sessions. All times are Eastern Time (ET).

Session	Hours (ET)	Days
Pre-market	4:00 AM – 9:30 AM	Monday – Friday
Regular	9:30 AM – 4:00 PM	Monday – Friday
After-hours	4:00 PM – 8:00 PM	Monday – Friday
Overnight	8:00 PM – 4:00 AM	Sunday evening – Friday morning

Regular hours exclude market holidays and early closes. See 📄 Market Holidays, Early Closes, Trading Halts, and Delays

Pre-market, after-hours, and overnight trading require the Extended Hours setting on your order ticket, and fewer order types are available. See 📄 Placing Orders in Pre-Market and After-Hours (Extended Hours) and 📄 Overnight Trading (24/6)

Order types outside regular hours

Supported order types may differ outside regular market hours. Use only the order types, time-in-force values, and extended-hours settings shown in your ticket. Not every account, symbol, venue, or order type is eligible for extended-hours trading.

Market orders generally seek immediate execution at available market prices and are normally associated with regular market-hours liquidity. Outside regular market hours, available order types may be limited, and displayed prices, bids, asks, or previews are not execution guarantees.
