About Norgate Data
Norgate Data is a premier provider of historical and end-of-day market data specifically engineered for rigorous quantitative analysis. Unlike standard retail data feeds, Norgate's architecture focuses on the removal of survivorship bias by providing comprehensive access to delisted securities and historical index constituents. By 2026, Norgate has solidified its position in the 'Quant-Stack' by offering a seamless bridge between high-quality normalized data and Python-based machine learning environments. The tool utilizes the Norgate Data Updater (NDU), a localized database management system that synchronizes cloud-hosted data to a local machine, allowing for ultra-fast, low-latency access during backtesting without the overhead of REST API calls. Its technical superiority lies in its granular treatment of corporate actions—such as splits, dividends, and spin-offs—offering users the choice between total return or price-only adjustments. This makes it an essential utility for institutional-level backtesting on platforms like AmiBroker, Wealth-Lab, and specialized Python libraries where data integrity is the primary determinant of model alpha.
