# Trading halts

`GET` `https://api.unusualwhales.com/api/socket/trading_halts`

**NOTE:**
This is the documentation for websocket channel `trading_halts`.
Websocket access for personal use is only available through the [Advanced plan](https://unusualwhales.com/pricing?product=api).

You can find fully-functional examples that stream data from many channels here:

- Python: [https://github.com/unusual-whales/api-examples/tree/main/examples/ws-multi-channel-multi-output](https://github.com/unusual-whales/api-examples/tree/main/examples/ws-multi-channel-multi-output)
- Javascript: [https://github.com/unusual-whales/api-examples/tree/main/examples/ws-multi-channel-multi-output-nodejs](https://github.com/unusual-whales/api-examples/tree/main/examples/ws-multi-channel-multi-output-nodejs)



Connect to the websocket URI:

`wss://api.unusualwhales.com/socket?token=<YOUR_API_TOKEN>`

then `join` the channel you wish to stream: `trading_halts` for live trading-state changes (halts, resumes, LULD pauses, etc.) sourced from UTP/CTA.

Payload format:

```

    "state": "halted",
