Source provenance
Data Sources
The European Central Bank is the raw official provider for the five launch products; Chronoverse owns the separate normalization and intelligence layer.
Launch universe
Current launch coverage is limited to EUR/USD, EUR/JPY, EUR/GBP, EUR/CHF, €STR. No additional market is implied by historical editorial coverage or legacy code.
European Central Bank observations
EUR/USD, EUR/JPY, EUR/GBP, and EUR/CHF use European Central Bank daily reference-rate observations. €STR uses the European Central Bank's official €STR series.
These sources provide official daily or reference observations. They are not real-time traded prices, streaming feeds, tick data, intraday data, or OHLC market bars.
Provider and Chronoverse boundaries
The ECB is the source of the raw official observations. Chronoverse validates identity and timestamps, normalizes those observations, and produces the analytical presentation. Chronoverse transformations are independent and are not produced, endorsed, or warranted by the ECB.
Provenance and revisions
Source identity, series identity, reference date, retrieval context, and availability should be read together. Upstream corrections, revisions, or gaps may change later analytical output.
