# Oracle Candles

> 5-minute OHLC candles from PolyNode's live Chainlink tick archive.

Returns 5-minute OHLC candles from PolyNode's live Chainlink tick archive for a given crypto asset. Approximately 30 candles (\~2.5 hours of history) are returned.

These are the same oracle prices used to resolve Polymarket's short-form crypto markets.

<ResponseExample>
  ```json theme={null}
  {
    "candles": [
      {
        "time": 1774665300,
        "open": 65954.03,
        "high": 65992.01,
        "low": 65947.14,
        "close": 65949.69
      },
      {
        "time": 1774665600,
        "open": 65949.69,
        "high": 65987.20,
        "low": 65949.69,
        "close": 65987.20
      }
    ]
  }
  ```
</ResponseExample>

<Note>
  Cached for about 5 seconds. The `symbol` parameter accepts bare asset symbols like `BTC` and feed names like `BTC/USD`. Each candle's `time` field is a Unix epoch timestamp marking the start of that 5-minute window.
