This page ranks the largest absolute premium and discount observations stored by this site for SGE, MCX, and the LBMA-related field, relative to the USD spot benchmark. A large difference does not identify its cause or prove market stress. Check the date, source, timestamp, and data status before interpreting any row.
The size of a premium alone cannot identify why two values differ. Timing, exchange rates, contract specifications, holidays, stale observations, taxes, liquidity, and vendor methodology can all affect the result.
This table ranks stored observations; it does not assign a historical cause, predict a future move, or identify a trading opportunity. The fixed status labels are display buckets based only on magnitude, not statistical confidence or a judgment that a market is functioning abnormally.
Interpret a row together with its timestamp, source, data-status label, and the period actually covered by this site's history. A short or interrupted history may not represent the long-run range of a market.
The view accepts a range of up to 1,095 days, but it can only display snapshots that still exist. The site records scheduled daily snapshots in Redis with expiration rather than in a permanent historical database. Missed cron runs, source failures, market holidays, and expired keys can therefore create gaps or shorten the available period. A longer range selection does not imply continuous or complete coverage; use the dates actually shown in the table.
A reading of +8.5% means the local market price was 8.5% higher than the USD spot benchmark on that day, after converting all currencies to USD per troy ounce. A negative number is a discount.
The calculation engine labels an absolute premium of 5% or less as "Normal", above 5% up to 15% as "High", and above 15% as "Abnormal". These thresholds are fixed constants — they describe reading size, not a judgment about whether the market is right or wrong.
The benchmark column is the Metals.dev USD/oz spot value stored for that date, not a specific COMEX contract settlement. It provides the benchmark level used in the calculation; the percentage and absolute USD difference should be read together.
The table ranks by absolute size, so a −7% discount and a +7% premium receive the same rank weight. The sign shows direction; the ranking does not identify why the difference occurred.
