What it does

International prices are quoted in dollars, per ounce, barrel or bushel. Indian buyers think in rupees, per gram, kilogram or quintal, after duty. This tracker does that conversion in the open:

India landed price = (international price ÷ unit conversion) × USD/INR × (1 + duty)

Each card shows one headline rupee price. Open Details for the full breakdown (purities, per-kg and per-10g values, contract-lot equivalents), the duty applied and the data source.

How the data stays live

Yahoo Finance does not allow direct requests from a browser, so a scheduled GitHub Action fetches it and publishes a small static file. Gold, silver, platinum and palladium spot prices are read directly by the browser.

Data	Source	How fresh
Gold, silver, platinum, palladium	gold-api.com spot, read by the browser	About every minute
Futures, USD/INR, FX strip	Yahoo Finance via the data branch	Scheduled every 5 minutes, but GitHub often runs schedules much less often (hours, on new or quiet repositories). The app shows the real age and flags it Stale after 20 minutes
Chart history and volume bars	Yahoo Finance via the data branch	Refreshed every 6 hours
Open interest, managed-money net	CFTC Commitments of Traders via the data branch	Weekly (as of Tuesday, published Friday)
Nine commodities with no free live feed	Typed-in indicative levels in app.js	As of 2026-06-12. Needs verification

The nine indicative commodities (zinc, nickel, lead, tin, iron ore, lithium, cobalt, canola oil, palm oil) are always badged Indicative. Their feeds are not freely available, and a stale feed shown as live would be worse than an honest label.

Notes on freshness: GitHub can delay scheduled runs at busy times and on new or quiet repositories (a first measurement here was one run in 13 hours). To keep data fresh, trigger Update prices from an external scheduler or press Run workflow. Also, and it pauses schedules in a repository with no activity for 60 days. The app flags any price older than 20 minutes as Stale.

Run it locally

Needs Node.js 18 or later. No packages to install.

git clone https://github.com/MrChartist/commodity-price-tracker.git
cd commodity-price-tracker
npm run dev

Open http://localhost:3000. The local server generates the same live data files the GitHub Action publishes, so it works without any setup.

Fork it and run your own

1. Fork this repository.
2. In Settings → Actions → General, allow workflows to run, with read and write permission.
3. In Actions, run Update prices and Update chart history and open interest once (they also run on a schedule). This creates the data branch.
4. In Settings → Pages, set the source to GitHub Actions, then run Deploy site.
5. Edit config.js and point dataBase at your fork:

   window.CPT_CONFIG = {
     dataBase: 'https://raw.githubusercontent.com/<you>/commodity-price-tracker/data',
   };

6. If you host the data anywhere other than raw.githubusercontent.com, also add that host to the connect-src list in the Content Security Policy <meta> tag of index.html.
7. Optional: change the CNAME file to your own domain, or delete it to use <you>.github.io/commodity-price-tracker.

Accuracy and limits

• Quotes are derived from international benchmarks. This is not NSE or MCX data, and Indian market prices will differ.
• Duty rates and their effective dates are entered by hand from public notifications. Needs verification against the latest CBIC notifications before you rely on them. Found a wrong rate? Open a data correction.
• Futures contracts roll, so a day change can occasionally look odd around a roll.
• For information and education only. Not financial or trading advice.

Contributing

Issues and pull requests are welcome. See CONTRIBUTING.md for how to run, test and propose changes, and SECURITY.md to report a security problem. Release notes are in CHANGELOG.md.

Good first contributions: a corrected duty rate with its source, a free live feed for any indicative commodity, translations, and accessibility fixes.
