Two decades of serious technical analysis, rebuilt for every desktop. AptiStockX is a professional charting workspace for self-directed traders — local data you own, 200+ indicators that just work, and a native app on Windows, macOS, and Linux.
AptiStockX is designed around the real workflow of technical analysts and active traders — deep indicator coverage, data you control, and a desktop application that respects your screen, your keyboard, and your time.
SMA, EMA, MACD, RSI (Wilder), Bollinger Bands, ATR, ADX/±DI, CCI, OBV, Parabolic SAR, Stochastic, Williams %R, and many more — every series computed locally from your own data.
Historical prices live as local CSV files you own and back up. Load from Stooq (free), Alpha Vantage, Tiingo, Alpaca, or your own files — no mandatory subscriptions, no rate limits on your own history.
A native Qt application that runs identically on Windows, macOS, and Linux. Workspaces, watchlists, chart templates, and indicator settings roam with you across every machine.
An MDI workspace with as many charts as you need — tabbed or tiled. Each chart keeps its own symbol, period, indicators, and saved studies. A live watchlist dock tracks all your symbols.
AptiStock has been the trusted charting companion of self-directed traders since 2005. Built before the cloud, it was always about one thing: giving serious traders a powerful, private workspace on their own machine.
I've been using AptiStock for 15 years. The indicator depth is unmatched for a desktop tool at this price point — everything from basic MAs to Gann angles. I've never had to install a plugin.— AptiStock user
What I love most is that my data is mine. I have daily data going back to 1990 for 3,000 stocks. It lives on my drive. No subscriptions, no expiry.— AptiStock user
It's fast. No spinners. I open it, load my watchlist, draw the setup. That's the workflow. Nothing gets in the way.— AptiStock user
I run the EOD download every evening, draw my levels, save the chart. The next morning everything is exactly where I left it. That kind of reliability matters when you trade seriously.— AptiStock user
Everything that made AptiStock trusted for 20 years is the foundation of AptiStockX — rebuilt for every platform, extended with modern data sources, and ready for the next two decades.
A redesigned chart engine, sharper price action, and an interface that gets out of your way. Same indicator depth, same local-first philosophy — now on every platform you use.

We're rebuilding AptiStock as a modern, cross-platform desktop charting application — keeping the local-first philosophy, the deep indicator library, and the focused workflow that long-time users rely on. The new release isn't available for download yet.
We're prioritizing features based on input from real users — analysts, swing traders, and long-term investors. If you used the legacy AptiStock, your feedback is especially valuable as we redesign the workflow.
Reach us at support@aptistock.com with feature requests, bug reports, or platform-specific notes.
We'll send one email when the download is ready. Nothing else — no newsletters, no marketing.
