Data Sources
Data Sources
Reference prices begin with international spot prices in USD captured at the snapshot close.
Foreign exchange rates from the same snapshot are applied to convert USD into local currencies.
Country tax and duty rules are maintained as static configuration and applied uniformly across pages.
Update Frequency
Update Frequency
Pages are generated at build time from the latest available snapshot and reflect its UTC timestamp.
Prices are not updated intraday and do not represent live trading or dealer quotes.
Reliability
Fallback & Reliability
The build is deterministic and uses a single snapshot for all pages to keep the dataset consistent.
If required inputs are missing, the build stops rather than publishing incomplete pages.
Changes are calculated against prior close data when available and shown as indicative deltas.
