Read the markets with precision, not guesswork.
A professional desktop charting suite for serious traders. 200+ technical indicators, your own local data, native on Windows, macOS, and Linux. Built on two decades of AptiStock heritage.
A real screenshot from the desktop build — not a mockup.
Hollow candles on a daily AAPL chart, four moving averages stacked, a horizontal volume profile on the right, a volume pane, and a MACD subpane — all rendered locally from your own data.
1M · 5M · 30M · 1H · D · W · M
One-click switching across intraday and end-of-day bars, with the same indicator stack preserved.
Multiple moving averages
Color-coded SMAs and EMAs render in real time over hollow candles, OHLC bars, Heikin-Ashi, Renko, or range bars.
Price-by-volume on the right edge
Horizontal histogram of traded volume by price level, computed locally from your own data — no external feed required.
Volume & MACD, deterministic
Standard volume bars and a fully-tuned MACD with histogram and signal lines. Every value is reproducible, every time.
Built for traders who do their own analysis.
No black boxes. No mandatory subscriptions. No browser tabs in the way of your charts.
200+ technical indicators
SMA, EMA, MACD, RSI, Bollinger, ATR, ADX, CCI, OBV, Parabolic SAR, Stochastic, Williams %R — the full library, computed locally with no rounding.
Your data stays on your machine
CSV files you own, back up, and control. Stooq, Alpha Vantage, Tiingo, Alpaca, or your own files. No mandatory subscriptions.
Cross-platform desktop
Native Qt application — runs identically on Windows, macOS, and Linux. Workspaces, watchlists, and templates roam with you.
Customizable workspaces
Multi-pane layouts, MDI tabs, dark/light themes, persistent .acht chart files — your setup is exactly where you left it.
AptiStock has been trusted by self-directed traders for nearly 20 years.
AptiStock was created in 2005 as a Windows desktop application for individual traders who wanted serious technical analysis without a brokerage-tied platform or an expensive Bloomberg terminal. 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.
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.
It's fast. No spinners. I open it, load my watchlist, draw the setup. That's the workflow. Nothing gets in the way.
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.
