market-data-fetcher

You can fetch historical market data from multiple sources by running the unified fetch script with a ticker and date range. The skill intelligently routes requests across Yahoo Finance, Stooq, and other configured providers, returning standardized columns.

Resolving ISIN numbers to tickers for cross-source comparison is handled by a centralized security master called the TickerRegistry. This registry maps ISINs to provider symbols, enabling seamless cross-source data validation.

Yes, you can retrieve cryptocurrency prices and FX rates alongside stock indices. The skill supports intelligent routing for crypto via CCXT, FX rates via NBP, and indices via Yahoo Finance, consolidating them into a unified format.

Yes, the market data fetcher works with pandas-datareader and FRED to retrieve economic indicators. It integrates these sources into its intelligent routing system, allowing you to download historical economic data alongside financial asset prices.

Using a multi-source routing approach instead of querying yfinance directly eliminates manual data alignment from disparate providers. It provides built-in caching for fast repeatable queries and cross-source validation that single-source APIs lack.

Limitations when fetching historical data from multiple providers depend on the rate limits and data availability of underlying sources like CCXT and beautifulsoup4. Built-in caching mitigates repeated request issues, but cross-source gaps may still occur.
