Data Sources
Every chart and number on MetalCharts ultimately comes from a primary source — an exchange, regulator, or central authority — not from a re-aggregator. This page lists every source we pull from, what we pull, how often, and where the underlying data comes from.
Why this page exists
Financial data sites routinely re-aggregate and re-package other sites’ data, sometimes with quiet transformations along the way (currency conversion, smoothing, deduplication) that introduce drift over time. The best defence against drift is transparency: tell readers exactly where the numbers come from, how often you pull, and what you do to them.
If you want to dig into how a specific metric is computed, every source on this page that has a dedicated methodology page is linked at the bottom of its entry.

Citing MetalCharts data
If you cite a chart or figure from MetalCharts in research, a blog post, or an article, please attribute the underlying source rather than us — e.g. “COMEX warehouse stocks via CME Group” rather than “MetalCharts”. We are an aggregator; the data itself belongs to the exchanges and regulators listed above.
If you do want to credit MetalCharts (much appreciated, helps us keep the lights on), “Chart: MetalCharts.org” with a link to the specific page is the format we prefer.
