Gann 9 is the only app that combines the power of AI with the legendary W.D. Gann’s tools and techniques (including the Square of 9) for analyzing, charting and trading any stock, forex or index. It will allow you to predict with high accuracy and confidence future support/resistance levels and change in trend (CIT) dates. Swing Angles are empowered with the unique ability to automatically select the correct angle step (rise, rate of vibration) applicable to any instrument in any time frame and price scale. Gann 9 is free to download. Gann 9 Pro, an optional subscription ($5.99 per month or $59.99 per year), unlocks AI Analyzer, options analytics, SAR and swing angles, DJIA History (120+ years of daily prices with cycle and correlation analysis) and the VIX module. New subscribers get 1 week free; after that renewal is automatic unless cancelled at least 24 hours before the end of the trial period. Manage or cancel it any time in Settings › your name › Subscriptions. Users who bought DJIA History, VIX or bar charts in earlier versions keep them. AI Analyzer summarizes the Gann 9 indicators for the symbol on your chart (the current and higher time frame, the combined CTF/HTF signal, Square of 9 levels, upcoming time windows, options levels and NYSE/NASDAQ market breadth) and explains them in plain English. The Market Pulse is written from the readings on your device; the VIX-pair summary uses Apple Intelligence where available. Options analytics show where options traders are positioned: the strikes with the largest call and put open interest, max pain, gamma wall, put wall and gamma flip, the expected move and implied volatility, which are also drawn on the chart. Built-in features include: * AI Analyzer: plain-English summaries of the readings (Gann 9 Pro) * Options data: open interest, gamma levels and expected move (Gann 9 Pro) * Ability to share charts and AI Analyzer cards * Trade signals and scanner * Tunnel indicator * Gann retracement and range squaring tool * Trend indicator and Trend matrix * Swing indicator and Swing matrix * Automatically drawn Swing Angles (Gann 9 Pro) * Swing exhaustion timer * Trend Bars™ * 130 years of DJIA price data (Gann 9 Pro) * Gann price and time calculator allowing user inputs * Automatic range retracement and extension analysis * Watchlists of up to 50 symbols each * Gann angles * Gann cycles * Square of 9 * Gann Seasonal Dates * Extensive User Guide * Trading Strategies section * Real time market data and breadth indicators * Multiple Watchlists synced between apps Whether you’re a novice or experienced market analyst, you’ll be able with a few taps to apply some of the most sophisticated technical analysis tools and to access AI and live trade signals at a fraction of the cost of traditional charting packages.
