Live XAU spot pricing and chart-range history are sourced from the official World Gold Council spot-price feeds first, with Gold API and Stooq retained as fallback feeds where available, and EUR and GBP market cards are converted from the latest ECB reference FX rates.
Treasury nominal and real-yield drivers come from the U.S. Treasury daily yield curve datasets, and are displayed on their original daily cadence.
If a feed is stale, the product shows last-known-good data plus an explicit stale indicator rather than hiding the module.
