We are an independent research project that aggregates precious metals price data from major global exchanges and publishes the resulting premium and discount measurements in a transparent, vendor-neutral way. This page explains who we are, how we work, what editorial standards we follow, and what limitations apply to our data.
Precious metals trade simultaneously on more than a dozen exchanges across multiple currencies, weight units, and tax regimes. The same gram of gold can carry a different price tag in Shanghai, Mumbai, London, and New York at the same moment, but most retail investors only see one local quote. Our mission is to make those structural price gaps visible and understandable, so that anyone — not just institutional desks — can reason about where the metal is cheap, where it is expensive, and why.
We publish four categories of information. First, real-time spot and exchange-traded prices for gold and silver from COMEX, the Shanghai Gold Exchange (SGE), the Multi Commodity Exchange of India (MCX), the London Bullion Market Association (LBMA), the Korea Exchange (KRX), and the Japan Exchange (JPX). Second, derived premium and discount percentages against the COMEX benchmark, calculated using a fixed and disclosed formula. Third, historical charts that let readers compare each market against the benchmark over time. Fourth, long-form editorial content — explainers, glossaries, tax comparisons, and methodology notes — that gives context to the numbers.
GoldSilver Tracker is published anonymously by a small distributed team. We are not a registered investment firm, broker, or news organization, and we do not solicit business from readers. We are also not affiliated with any of the exchanges we cover. Each of the roles below describes a function within the project rather than a single named individual; in practice, several contributors rotate through these responsibilities.
Maintains the daily reading of each covered market: which contract is the active month on COMEX, which Au9999/Ag(T+D) is the reference instrument on SGE, what the prevailing import duty regime is in India, when fixing windows open in London. Reviews and signs off on every methodology change before it ships.
Expertise: Commodity microstructure, exchange rules, central bank gold reserves, import/export regimes.
Owns the ingestion pipeline that pulls prices and FX rates from Metals.dev, GoldAPI, the SGE GraphQL endpoint, JPX settlement-price CSVs, the KRX Public Data Portal, and ExchangeRate-API. Implements the unit normalization (everything to USD per troy ounce), the cache layer (Vercel KV / Redis), and the cron schedules that refresh the dataset. Designs the fallback chain that runs when a source goes down.
Expertise: Distributed systems, time-series caching, REST/GraphQL integration, schema design, observability.
Responsible for every word a reader sees. Drafts and edits the explainers, glossary, tax-comparison tables, and methodology notes, then has them reviewed by Market Research for technical accuracy. Decides what gets translated and into which of the four languages we publish (English, Korean, Simplified Chinese, Japanese). Maintains the editorial standards described below.
Expertise: Financial journalism, multilingual content design, structured data / SEO, plain-language explanation.
These standards govern every page on the site, whether it is a data table, a chart, or a long-form article.
We accept programmatic display advertising (Google AdSense) but do not run sponsored content, "best broker" rankings, or affiliate referrals to trading platforms. No third party can pay to alter a price reading, a premium calculation, or the wording of an article.
Every numeric claim in our editorial content is either traceable to one of the price feeds documented on the methodology page or explicitly marked as a representative example. Where exchange rates and import duties change, we update inline rather than rewriting history.
When we discover an error in a published article — wrong unit conversion, outdated tax rate, mistranslated term — we update the article inline and add a dated note at the bottom describing what was corrected. We do not silently overwrite mistakes.
We do not tell readers whether to buy or sell. Premiums and discounts are descriptions of structural market conditions, not buy or sell signals. Wherever we describe how investors might interpret a number, we frame it as one of several views rather than a recommendation. See the disclaimer page for the full statement.
No price aggregator is perfectly accurate at all times — exchanges go offline, APIs return stale values, currencies fluctuate between snapshots. The following commitments describe what we do to keep our error rate low and to communicate honestly when something goes wrong.
Multi-source cross-checks
Spot gold and silver are pulled from Metals.dev as the primary feed and GoldAPI as the fallback. When the two disagree by more than 0.5%, the pipeline logs the gap for manual review before publishing.
Exchange-native prices wherever possible
For SGE, MCX, KRX, and JPX, we do not derive prices from the global spot — we read each exchange directly (SGE GraphQL, MCX via Metals.dev mcx_gold/mcx_silver fields, KRX Public Data Portal, JPX settlement-price CSV). This is how a real premium can emerge instead of being mechanically zeroed out by the same source.
Stale-data flagging
Every cached entry carries a timestamp. When a feed has not refreshed within its normal cadence — for example, SGE returning the same value on a Sunday because the exchange is closed — the cache treats the entry as derived rather than live, and downstream code refuses to publish it as a fresh quote.
Versioned methodology
When we change how a number is computed — for example, swapping the active COMEX contract month, or changing the silver T+D divisor on SGE — we ship the change to the live site and the methodology page in the same release, never one before the other.
A real human reading on errors
Pipeline errors, schema drift in external APIs, and large premium spikes are routed to the team rather than being silently swallowed. The goal is for a human to confirm whether a 9% premium really happened or whether one feed broke.
You cannot buy or sell gold or silver on this site. We display prices originated elsewhere; we do not match orders, take custody of metal, or hold customer funds.
Our prices refresh on a schedule (intra-day cache + daily snapshot), not tick-by-tick. Traders who need sub-second pricing should go directly to a market data vendor or to the exchange.
No one on the editorial team is a licensed investment adviser. Our coverage is journalism plus data engineering, not personalized recommendations. Anything that looks like a forecast on this site is an illustration of a possible interpretation, not advice tailored to your situation.
The tax comparison page summarizes import duty, VAT, and capital-gains regimes at a high level. Real tax outcomes depend on your residency, account structure, holding period, and product (bars vs coins vs ETFs). Talk to a local tax professional before you transact.
If you have spotted a calculation error, a stale tax rate, a mistranslated term, or a contract month that has rolled, we want to hear about it. Corrections are taken seriously and acknowledged. The fastest channel is the contact page; we read every message.
