Parameters
Query Parameters
The symbol of the security. Option underlyings for indices might have special tickers.
The start date (inclusive) of the request formatted as YYYYMMDD.
The end date (inclusive) of the request formatted as YYYYMMDD.
The interval size in milliseconds. 1 minute intervals is 60000. Omitting this value or setting it to 0will provide tick-level data instead of aggregated / intervalized data.
If this value is set to false and the request is for aggregated / intervalized data, the response will contain intervals from 00:00:000 ET to 23:59:999 ET. If the ivl is 0 or is unspecified, then rth will be forced to false. This means that all data for the day, even if it was outside regular trading hours would be returned. The default behavior is to only return data during regular trading hours (09:30:00.000 ET to 16:00.000 ET).
If specified, the response will include all ticks on or after this number of milliseconds since midnight ET.
