The first timestamp of the timeseries.
Accepted formats:
- ISO 8601 date stamp (e.g. "2021-03-16", parsed as UTC)
- ISO 8601 datetime (e.g. "2021-03-16T18:38:01Z", "2021-03-16T18:38:01-04:00")
- Unix timestamp
Defaults to end - period.
When timeframe=1D, if start occurs any time on a trading day (including outside of market hours), start is set to the closing time of the current trading day. Otherwise, start is rolled forward to the closing time of the next available trading day.
When timeframe != 1D, one of the following rules is applied.
- When
intraday_reporting=continuous, start is rolled back to the nearest timeframe interval.
- When both
start and end are omitted, start is rolled back to the first market/session open that is encountered.
- When
intraday_reporting != continuous and start is a trading day:
- roll forward to the first market/session open if
start is outside of market/session hours, or
- roll back to the nearest
timeframe interval if start occurs during trading hours.
- Roll forward to the next market/session open if
start does not fall on a trading day.
start may be combined with end or period, but cannot be combined with both.
