OT Fibonacci harnesses the power of AI and automates the process of objectively defining price and time targets, and of applying Fibonacci numbers, ratios and time series to any stock, index or forex pair chart. It will help you calculate price targets, wave extension and retracement levels. It also introduces a new set of original Technical Analysis indicators and trading signals designed to help you make quick and informed investment decisions. OT Fibonacci is free to download. OT Fibonacci Pro, an optional subscription ($5.99 per month or $59.99 per year), unlocks AI Analyzer, options analytics, bar charts, DJIA History (120+ years of daily prices with cycle and correlation analysis) and the VIX module. AI Analyzer reports the OT Fibonacci indicators for the symbol on your chart (the current and higher time frame, the combined CTF/HTF signal, Fibonacci retracement and extension levels, upcoming Fibonacci and Lucas 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, drawn on the chart. New subscribers get 1 week free; after that OT Fibonacci Pro is $5.99 per month or $59.99 per year and renews automatically unless cancelled at least 24 hours before the end of the trial period. Manage or cancel it any time in Settings › your name › Subscriptions. Built-in features include: * AI Analyzer: plain-English summaries of the readings (Pro) * Options open interest, gamma levels and expected move (Pro) * Ability to share charts and AI Analyzer cards * Wave and Trend indicator * Fibonacci retracement tool * Trend Bars™ * Trading signals and scanners * Swing indicator and Swing matrix * Swing exhaustion timer * Clear, objective and unbiased price wave display * Fibonacci price and time calculator allowing user inputs * Automatic range retracement and extension analysis * Fibonacci and Lucas cycles * Trend matrix * Trading Strategies section * Market data and breadth indicators * Watchlists of up to 50 symbols each * Multiple Watchlists synced between apps Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://fibonacciapp.blogspot.com/p/privacy-policy_06933842.html
