Options Activity Scanner & Web Dashboard

I need a web-based dashboard, powered by the DhanHQ API, that continuously scans NSE and BSE option chains and fires in-app alerts whenever unusual activity appears. All the core metrics—RVOL, GEX, VEX, Gamma-Regime, Vex-Regime, Charm, CE & PE walls, Gamma-flip level, Dealer-Flow Score, and IV Rank/Percentile—must be user-configurable from the interface so I can tweak thresholds on the fly without touching code. The workflow I have in mind is simple: the backend fetches live data, applies my chosen parameter settings, calculates the signals, and streams results to a responsive web UI. When any metric crosses the threshold, the system should display a notification inside the application immediately and log the event for later review. Real-time charts, heat-maps, and summary tables that update automatically will help me understand context at a glance. Because fast data matters, please design efficient polling or websockets (whichever the DhanHQ endpoints allow) and cache sensibly to avoid hitting rate limits. A secure login, preset management, and a clean layout that works on desktop browsers and tablets round out the experience. Deliverables • Fully functional web dashboard (frontend + backend) • Parameter panel to add/edit thresholds and save presets • Real-time in-app alert module with history log • Source code, deployment guide, and short video walkthrough The project is complete when the scanner reliably flags unusual activity in live market hours and all listed metrics can be adjusted by me through the UI without redeploying.
