24/7 Blended Precious Metals Feeds
24/7 blended precious metals price feeds are custom feeds designed to publish a precious-metals-linked price both during and outside regular precious metals market hours. They use a bespoke methodology rather than a continuously open physical precious metals spot market.
Developers integrating these feeds should review this page alongside the Custom Feeds section and implement risk mitigation appropriate for their use case.
How it works
During open precious metals market hours, the feed reports the underlying precious metals spot price (for example, XAU/USD for gold). When the precious metals market is closed, the feed starts from the last observed open-market price and adjusts it with a blended signal derived from tokenized precious metals price streams.
For example, the current tGLD/USD implementation uses XAUT/USD and PAXG/USD streams for the closed-market signal. For each available tokenized precious metals stream, the adapter tracks the token's open-market premium or discount to the spot price with an EMA, uses that value to derive a spot-equivalent tokenized price, averages the valid derived prices, and smooths the resulting deviation from the last spot price with another EMA. The composite price applies configurable weighting and deviation controls before the closed-market adjustment is reflected in the answer. Other blended precious metals feeds may use different tokenized streams or methodology variations.
