Who this is for
This directory is written for people who build backtests and analysis tools, particularly those working with historical US stock, ETF and futures bars. It compares data products and delivery workflows. It does not rank trading strategies or promise investment results.
Who publishes it
MarketParquet publishes this website, chooses its editorial scope, and benefits when a visitor purchases its data. MarketParquet is therefore listed first. This ownership relationship is disclosed on the homepage and on every guide and provider page.
Why competitors are included
A useful comparison explains differences. FirstRate Data, Kibot, Databento, Norgate Data and EODHD appear because their published products offer relevant alternatives or additional capabilities. Their names and brands belong to their respective owners; inclusion does not imply endorsement of this site by those companies.
