Research and choose real market data source #32
Description
Goal
Research and choose a real data source for ARGUS analytics.
Why
ARGUS currently uses mock time-series data for early analytics development. Sprint 2 needs a real data client next to the existing ExchangeRate API client so market metrics can be calculated from real data.
The existing ExchangeRate API client should remain useful for live currency conversion, while the new client should focus on exchange-rate and market data.
Scope
- Compare possible data sources
- Check API capabilities:
- historical date ranges
- supported currency pairs or symbols
- response format
- rate limits
- authentication requirements
- pandas compatibility
- Decide which client should replace the mock time-series client first
- Document the decision in
docs/
Acceptance criteria
- At least two data-source options are compared
- Existing ExchangeRate API role is clarified
- Recommended first historical data source is selected
- Data format and response structure are documented
- Limitations and trade-offs are documented
- No production implementation is required in this ticket
