Market Hours and Extended-Hours orders

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

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.

Contact support if

• An order cannot be submitted even though the ticket appears to allow it.

• A submitted order was rejected and you need an account-specific explanation.
• A live order cannot be canceled.
• You have a financial harm concern, a missing fill, a wrong fill, or another trade dispute.
