HistoricalData.net: U.S. Market History for Research and Backtesting
HistoricalData.net provides accurate, research-ready U.S. stock and options historical market datasets at affordable prices. Coverage includes U.S. stock history from November 2003 onward and U.S. options end-of-day (EOD) history from May 2002 onward, covering thousands of symbols and major indexes across the U.S. market.
The datasets are built for backtesting, quantitative research, academic studies, and data analysis. Researchers can use the data to study investment approaches, evaluate trading strategies, and build repeatable backtests with reproducible CSV/ZIP archives rather than a real-time trading feed.
