Data Sources

Where our numbers come from and how we use them — official releases, exchanges, filings, surveys, and vetted vendors. We link out, validate, and document methodology.

We prefer official sources: regulators, exchanges, ministries, and company filings.
Traceable
Every chart or metric can be traced to a public link or documented dataset.
Cadence-aware
We flag refresh frequencies (daily, weekly, monthly, ad-hoc) and expected lags.
