Trade Spark

Simple tools, smarter trading, brighter decisions.

A live market dashboard for Indian indices and global markets. Charts, heatmap, movers, and technicals come from TradingView widgets. The app is a static Progressive Web App — install it from the browser and use it like a standalone window.

Features

• Dark theme by default, with a light/dark toggle
• Live ticker for Sensex, Nifty 50, Bank Nifty, Bitcoin, DXY, and S&P 500
• Mini overviews for Sensex, Bankex, BTC, and FTSE 100
• Advanced Sensex chart with details, hotlist, and SMA
• Market news, BSE hotlists, and Sensex sector heatmap
• Technical ratings for Sensex, Nifty, Bank Nifty, and Nifty MidCap 100
• Custom watchlist with Yahoo Finance live search, company logos, quotes (price, change, open, previous close, day range, volume, 52-week range), and a 1-month sparkline, saved in this browser
• Installable PWA with offline shell (market widgets still need a network connection)

Run locally

Open the files over HTTP. A service worker cannot register from a file:// URL. Use serve.py so the watchlist can load Yahoo Finance quotes through /api/quote.

python serve.py

Then visit http://127.0.0.1:8765/.

Install as an app

Serve the site over HTTP or HTTPS (not file://). In Chrome, install from the address bar or Customize and control Google Chrome → Cast, save, and share → Install page as app. On iOS Safari, use Share → Add to Home Screen.

Deploy

The site is static plus one serverless quote route. Vercel will serve api/quote.js automatically. Keep these files at the site root:

• index.html
• manifest.json
• sw.js
• api/quote.js
• api/search.js
• favicon.svg / favicon.ico
• icons/
