Data Sources #

Authoritative market and instrument data sources used by AIMS and the boundaries for durable knowledge updates.

Repository facts #

AIMS fetches daily OHLCV history from Stooq using its free CSV download API. Configured Stooq symbols are maintained in data/stooq_symbols.txt.

The CFD instrument master is a separate data source maintained in data/cfd_instruments.csv. It is refreshed by the weekly updater workflow and validated before the daily market analysis workflow runs.

Source-of-truth boundary #

AIMS keeps numeric market facts, scores, ranks, dates, risk gates, and data availability in generated artifacts and validated reports. This OKF concept captures durable repository knowledge only.
