SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

yfinance removes the friction of collecting Yahoo Finance market data so traders can immediately feed OHLCV, corporate actions, and holdings into backtests without API keys or manual scraping.

Core Features & Use Cases

  • Unified loader: The built-in yfinance DataLoader (or auto source) translates project tickers into Yahoo format and handles batching for US, HK, ETF, index, and FX assets.
  • Comprehensive coverage: Download minute-to-month OHLCV, company info, financial statements, dividends, splits, and institutional or insider records through the same interface.
  • Use case: Backtest a cross-market strategy by setting source to yfinance (or auto) and pulling AAPL.US, 0700.HK, and SPY.US data plus the latest quarterly financials in one go.

Quick Start

Ask the agent to fetch AAPL.US daily OHLCV for January 2025 through yfinance to seed a new strategy run.
