HistoricalDataResult

Common result-page metadata shared by NAV and metric responses.

Field	Type	Required	Nullable	Default	Description
ContinuationToken	str	No	Yes		Pagination token for the next page. For Raw open-ended tail-following queries, this stays non-null even when the current tail is exhausted. For bounded queries, null/empty means all points in the effective window were returned.
RawAvailableFromUtc	datetime	No	Yes		Oldest UTC instant for which HistoricalDataResolution.Raw points can be served by this API. This is the later of the hub's raw access cap and the raw storage retention cutoff. Null when raw serving does not apply.
RawStitchStartUtc	datetime	No	Yes		UTC instant where HistoricalDataResolution.Auto switches from rollup buckets to raw samples. Clients can use this as the intraday chart stitching/smoothing boundary. Null when no stitch boundary applies, including Auto queries that are served from rollups only because the intended raw tail is no longer fully retained.
EffectiveEndUtc	datetime	No	Yes		Effective exclusive upper bound used by the server. For Auto/Rollup queries with null EndUtc, this is the materialized snapshot end. Null only for Raw open-ended tail-following queries.
Payload	HistoricalDataPayload	Yes	No		Compressed or uncompressed UTF-8 JSON payload containing the page series.
