Displays stock Sector & Subsector info on TradingView. Includes a full watchlist with tabs, sections, notes & import/export. SectorLens — Stock Sector Info & Watchlist Manager for TradingView SectorLens is a powerful Chrome extension built for stock traders who use TradingView. It combines two essential tools into one sleek, always-available panel: instant NSE stock sector & subsector identification, and a full-featured personal watchlist manager — all without ever leaving your chart. Whether you are a day trader, swing trader, or long-term investor tracking the Indian stock market, SectorLens gives you the context and organisation you need right on your TradingView chart page. ───────────────────────────────────────── 🔍 SECTOR & SUBSECTOR IDENTIFICATION ───────────────────────────────────────── Every time you switch to a new stock on TradingView, SectorLens instantly tells you which sector and subsector that stock belongs to. No more switching tabs, no more searching the internet — the information appears automatically in a compact floating panel on your chart. • See the exact NSE sector (e.g. Financial Services, Technology, Energy) for any stock • See the precise subsector (e.g. Private Sector Bank, IT Consulting & Software, Oil & Gas) • Panel updates automatically whenever you switch to a new symbol • Works across all NSE-listed stocks • Clean colour-coded accents for each major sector so you can identify the category at a glance • Non-intrusive draggable panel — position it anywhere on your screen This feature is invaluable for: - Quickly understanding what a stock does when you encounter it for the first time - Checking whether a breakout stock belongs to a hot sector - Avoiding over-concentration by spotting when multiple watchlist ideas are from the same sector - Confirming sector rotation themes during market analysis ───────────────────────────────────────── 📋 FULL-FEATURED WATCHLIST MANAGER ───────────────────────────────────────── SectorLens includes a complete watchlist manager built directly into TradingView — no popup, no separate tab. It slides out as a side panel without disrupting your chart view. MULTIPLE WATCHLISTS (TABS) Create as many watchlists as you need. Switch between them with a single click. Each watchlist is completely independent with its own sections and symbols. Examples of how traders organise their watchlists: - "Swing Trades" / "Long Term" / "Watchlist" / "Earnings Week" - "Nifty 50" / "Midcap" / "Smallcap" - "Breakouts" / "Retracements" / "Sector Leaders" SECTIONS WITHIN EACH WATCHLIST Each watchlist can have multiple named sections, so you can group stocks by theme, sector, strategy, or any criteria you choose. Add as many sections as you like. Delete sections you no longer need. SYMBOL SEARCH WITH AUTOCOMPLETE Start typing any NSE stock name or symbol in the search bar, and SectorLens instantly shows matching results from the complete NSE symbol database. Select any result to add it to your currently selected section. The search covers both ticker symbols (e.g. RELIANCE) and full company names (e.g. Reliance Industries). ONE-CLICK SYMBOL SWITCHING Click any stock in your watchlist to instantly switch the TradingView chart to that symbol. The watchlist remains open and exactly where you left it — no page reloads that reset your layout. NOTES FOR EVERY STOCK Attach a personal note to any stock in your watchlist. Use notes to record: - Your trade idea and rationale - Entry/exit targets - Key levels to watch - Earnings dates or events - Risk management rules for that position Notes are saved automatically and shown with a small indicator on the stock row so you always know which stocks have notes attached. RENAME WATCHLISTS AND SECTIONS Double-click any watchlist tab name or section name to rename it instantly. Press Enter to save, Escape to cancel. Names are saved immediately. DELETE STOCKS EASILY Remove any stock from your watchlist with a single click. A quick confirmation ensures you don't accidentally delete stocks. DRAG AND DROP REORDERING Rearrange stocks within a section by dragging them to the position you want. Keeping your most important stocks at the top has never been easier. KEYBOARD NAVIGATION Navigate your watchlist without using the mouse. Hover the watchlist panel and use: - Arrow Up / Arrow Down to move through your stock list - Enter to switch the chart to the highlighted stock Perfect for rapid scanning during pre-market prep or live market hours. ───────────────────────────────────────── 💾 IMPORT & EXPORT ───────────────────────────────────────── Take full control of your watchlist data: EXPORT Export all your watchlists to a single JSON file with one click. Use this to: - Back up your watchlists before clearing your browser data - Transfer your watchlists to another device or browser profile - Share your watchlist setup with a colleague IMPORT Import a previously exported JSON file to restore or merge your watchlists. SectorLens intelligently merges the imported watchlists with your existing ones — it does not overwrite, it combines. Duplicate stocks are automatically handled. ───────────────────────────────────────── 🎨 DESIGN & THEME ───────────────────────────────────────── SectorLens is designed to feel native to TradingView's dark interface. The panel uses a dark glassmorphism aesthetic — a frosted dark glass look with subtle transparency, smooth borders, and clean typography that blends naturally with TradingView's own UI without clashing or distracting from your charts.
