Get Current Market Status
This endpoint retrieves the current status of the market, including whether it is open or closed, and any relevant information about trading pauses or restrictions. When the market is not open, the response provides details about the closure reason and expected reopening time.

GM observes the same holiday schedule as the New York Stock Exchange. This includes early closes and observed holidays.
Unscheduled Downtime
In the case of unscheduled downtime, trading may be paused without prior notice. This includes unexpected outages or maintenance events that impact GM’s functionality.
Market Status Reason Codes
When the market is not open, the response will include a reason field which may include one of the following common codes:
MARKET_CLOSED: Market is closed.MARKET_PAUSED: Market is temporarily paused.
Off-Hours Trading
The offhours object reports the off-hours trading window as a parallel track alongside the conventional sessions. marketStatus, isOpen, nextOpenSession, nextOpen, and nextClose only reflect the four conventional sessions (regular, premarket, postmarket, overnight); a weekend or holiday with no active conventional session reads as closed on these fields. Off-hours tradability is reported separately via offhours.isOpen, offhours.nextOpen, and offhours.nextClose. The offhours.nextOpen and offhours.nextClose schedule fields are reported regardless of the off-hours global switch, while offhours.isOpen is true only when the off-hours window is tradable.
Asset Tradability This endpoint only returns market-wide closures. For per-asset tradability, use the following endpoints:
- Individual assets may pause for dividends and other events, as indicated by
/v1/status/assets. (See Get Asset Statuses) - Certain assets do not trade during the overnight and pre/postmarket session, as indicated by
/v1/assets/{symbol}/market. (See Get Market Data for an Asset / Get Market Data for All Supported Assets)
