Read full descriptionHide full description
Trade Alert is a native iPhone, iPad and Apple Watch experience designed for investors who track Brazilian B3 tickers and want fast, reliable alerts right on their devices. Search B3 companies by ticker, save favorites, and create custom alert rules for price thresholds or percentage moves. Configure weekday windows, active hours, polling frequency, and notification cooldowns so your devices only buzz when it matters. It supports both standalone watch use and paired iPhone scenarios, letting you manage alerts and notification preferences from the watch. AI Outlook is optional and off by default. When enabled, it uses Yahoo chart candle data and an open-source Kronos-based forecasting backend to provide visual decision support for selected tickers, including projected candle direction, forecast range, support and resistance levels, technical drivers, and risk warnings. Kronos is an academic open-source time-series forecasting project. Users can review the research paper at https://arxiv.org/abs/2508.02739 and the source code at https://github.com/shiyu-coder/Kronos. Key features: - Search and track B3 tickers from Brazilian stock exchanges - Save favorite companies and monitor live price changes - Create price and percentage alert rules with flexible schedules - Receive push alerts on Apple Watch when rules trigger - Use a standalone watchOS app with server-backed delivery - Enable AI Outlook for visual candle forecasts and decision-support signals - Review Kronos research and source-code references from the app - Keep the backend secure with private OneSignal registration AI Outlook forecasts are probabilistic and can be wrong. Yahoo chart data may be delayed or incomplete. Trade Alert provides decision support only and does not provide investment, financial, tax, or legal advice. Trade Alert is built for investors who want market awareness without opening their phone. It brings the most important B3 price movements to your wrist, so you can stay informed while on the move.
