When the market is not open, the response provides details about the closure reason and expected reopening time. **Typical Market Sessions** The following table outlines the standard market sessions with brief transitional pauses between each session period. | **Session** | **Start Time** | **End Time** | |:-----------------|:---------------:|:--------------:| | Pause | 3:55 AM ET | 4:01 AM ET | | **Premarket** | **4:01 AM ET** | **9:29 AM ET** | | Pause | 9:29 AM ET | 9:31 AM ET | | **Regular** | **9:31 AM ET** | **3:59 PM ET** | | Pause | 3:59 PM ET | 4:01 PM ET | | **Postmarket** | **4:01 PM ET** | **7:59 PM ET** | | Pause | 7:59 PM ET | 8:05 PM ET | | **Overnight** | **8:05 PM ET** | **3:55 AM ET** | **Typical Holidays** GM observes the same holiday schedule as the [New York Stock Exchange](https://www.nyse.com/markets/hours-calendars). 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. **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](https://docs.ondo.finance/api-reference/status/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](https://docs.ondo.finance/api-reference/assets/get-market-data-for-an-asset) / [Get Market Data for All Supported Assets](https://docs.ondo.finance/api-reference/assets/get-market-data-for-all-supported-assets)) For caching details on this endpoint, please see: [Endpoint Caching](https://docs.ondo.finance/api-reference/endpoint-caching). ## OpenAPI ````yaml /gm-be-api-spec.json get /v1/status/market openapi: 3.0.4 info: title: GM Backend API description: An API spec for the Ondo GM Backend API. version: 1.0.0 servers: - url: https://api.gm.ondo.finance description: GM Backend API security: [] tags: - name: Attestations description: Get Mint and Redeem Attestations - name: Assets description: Get Asset Price Information - name: Tickers description: Get Ticker Information - name: Chains description: Get On Chain Data - name: Limits description: Get Trading Limits - name: Status description: Get Market and Trading Statuses paths: /v1/status/market: get: tags: - Status summary: Get Current Market Status description: > 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.
