The server returns an acknowledgement first. Channels with cached state may send a snapshot; trades is delivered as update events. Subsequent messages use type: "update".

`pred.trades`

Subscribe with condition_id. Response example

{
  "t": 1720000000124,
  "trace_id": "trace-1",
  "type": "update",
  "ch": "pred.trades",
  "err": null,
  "result": {
    "condition_id": "ge_condition-1",
    "token_id": "ge_token-yes",
    "outcome": "Yes",
    "side": "BUY",
    "px": "0.45",
    "qty": "10",
    "ts": 1720000000123
  }
}

`pred.depth`

Subscribe with token_id and level. Supported levels are 5, 10, 20, and 50. The response is a full book, not a delta. Response example

{
  "t": 1720000000124,
  "trace_id": "trace-1",
  "type": "snapshot",
  "ch": "pred.depth",
  "err": null,

    "full": true,
    "bids": [
      ["0.44", "100"]
    ],
    "asks": [
      ["0.46", "80"]
    ],
    "hash": "book-hash",
    "ts": 1720000000123
  }
}

  }
}

    "condition_id": "ge_condition-1",
    "slug": "example-market",
    "status": "ACTIVE",
    "closed": false,
    "accepting_orders": true,

        "token_id": "ge_token-yes",
        "px": "0.45"
      },

        "px": "0.55"

    "price_timestamp": "1720000000123",
    "ts": 1720000000123
  }
}

`pred.candlestick`

Subscribe with symbol and interval. Response example

    "h": "100010.00",
    "l": "99990.00",
    "c": "100005.00",
    "v": "0",

A cached candlestick snapshot contains symbol, interval, and history.

`pred.oc_price`

  "type": "update",
  "ch": "pred.oc_price",

    "price_to_beat": "100000.00",
    "final_price": "100120.00"
  }
}

Unless a field is explicitly documented as seconds, timestamps are Unix timestamps in milliseconds.
