GOLDPRICE.TRADING
Data Methodology
How goldprice.trading handles sources, units, timestamps, fallbacks and elasticity calculations.
Quotes and units
Original market units are retained and normalized to USD per troy ounce, per gram and local currency. One troy ounce equals 31.1034768 grams.
Time and freshness
All timestamps display in UTC. Live, delayed, fallback and unavailable states are distinct; fallback values are never presented as live.
Elasticity matrix
Common-date daily changes estimate beta(row ← column)=Cov(row,column)/Var(column). Return assets use percent moves and yield factors use 10bp changes.
News method
Public RSS discovers headlines; deterministic keywords screen category and direction while the original publisher remains the source of record.
Versions and corrections
The review date changes after material methodology updates. Source-verified errors are corrected without backfilling away collection gaps.
