Screener-Extension
📈 Screener & Market Tracker Extension
A powerful Chrome extension that acts as a real-time mirror to your Screener.in account and Yahoo Finance, bringing financial data, stock watchlists, and market indices directly to your fingertips on any webpage you visit.
✨ Features
- 🚀 Live Ticker Tape: See real-time price updates and percentage changes for NIFTY 50, SENSEX, and your personal watchlist across the top of any webpage.
- 📌 Floating Watchlist Widget: A draggable, collapsible widget that stays with you on any webpage. Instantly check current prices, P/E ratios, Market Cap, and ROCE without leaving your active tab.
- 🔄 Screener.in Integration: The extension securely scrapes your customized ‘Top Ratios’ from your Screener.in dashboard. Add a new metric on Screener, and it instantly syncs to the extension.
- 🧠 Smart AI Verdict: Get an instant, color-coded health check (Undervalued, Overvalued, High Risk) based on the stock’s P/E and ROCE ratio.
- 📁 Multiple Portfolios: Create and manage distinct portfolios (e.g., Long Term, Swing Trades) directly from the side panel.
- 📰 News Feed: Stay updated with the latest Yahoo Finance news for the top stocks in your active portfolio.
- 📊 Export to CSV: Download your entire watchlist and ratios to Excel with a single click.
- 🌙 Dark Mode: Fully supports dark mode for comfortable reading during late-night research.
⚙️ How It Works
This extension does not rely on a costly backend server. Instead, it securely acts as a local frontend:
- Screener.in: For financial ratios (P/E, ROCE, Market Cap). Note: You must be logged into Screener.in on your browser for the data to sync properly.
- Yahoo Finance: For live stock prices, market indices (NIFTY 50), and the latest financial news.
