Concepts

Use these pages when you need to understand what yfin returns, not just which endpoint to call.

Core Topics​

  • Symbols: ticker formats, lookup, regions, and asset types.
  • Data Freshness: how to think about quote freshness, delayed markets, and historical updates.
  • Historical Prices: ranges, intervals, candles, and chart response shape.
  • Adjusted Prices: adjusted close, dividends, splits, and yfinance-compatible adjustment options.
  • Market Hours & Timezones: market state, session times, and timestamp handling.
  • Missing Data: null fields, unavailable datasets, empty result sets, and invalid symbols.
  • Financial Fields: common quote and fundamentals field meanings.

Where Concepts Fit​

Concept pages explain durable behavior across endpoints. For exact parameter lists, response schemas, and examples, use the API Reference. For copy-paste tasks, use the Guides.
