AptiStockX is a local-first desktop stock charting and portfolio research application for Windows, macOS, and Linux. It is the modern continuation of AptiStock, first released in 2005.
AptiStockX focuses on native desktop charting, local chart files, local workspaces, watchlists, downloaded market data, provider-separated data workflows, technical indicators, drawing tools, multi-monitor charting, and optional AI-assisted chart review.
Basic is free for core charting workflows. Pro is a paid license that unlocks deeper charting workflows, more workspace flexibility, multi-monitor features, advanced studies, intraday workflows where provider data allows, and AI Assistant features.
AptiStockX is research and charting software for self-directed traders and researchers. It is not a broker, investment adviser, financial adviser, market-data vendor, or trade execution service.
