COMEX Contract Month Roll: A Practical Guide to Reading the Active-Month Transition

What "Active Month" Means and Why It Rotates

COMEX gold and silver futures are listed for delivery in many different months at any given time. There is a February gold contract, an April gold contract, a June gold contract, and so on out to years in the future.

Each is a separate financial instrument with its own bid, offer, open interest, and eventual delivery period.

Market reports and data vendors may select one contract as a representative or active month. The selection rule can be based on volume, open interest, a scheduled roll date, or the vendor's own methodology, so the chosen contract is not necessarily identical across sources.

GoldSilver Tracker does not use an active COMEX futures contract as its dashboard benchmark. Its benchmark is a vendor-supplied aggregated USD spot observation. The internal identifier comex remains for compatibility, but it should not be interpreted as a specific COMEX delivery month.

Listed Contract Months and Representative Contracts Are Different Concepts

CME Group lists gold and silver futures for multiple contract months. The months available for trading are not necessarily the same as the months carrying the most volume or open interest at a particular time.

Statements such as "gold rolls in even-numbered months" or "silver rolls in selected odd-numbered months" should not be treated as fixed rules for every participant or data vendor.

Current contract months, last-trade dates, notice dates and delivery procedures should be checked in CME Group's current contract specifications and calendar.

How Roll Transitions Are Observed

As expiry and delivery-related dates approach, some participants may close positions or move them to another contract month. However, the timing of the move and the destination contract depend on each participant's objectives, on available liquidity, on contract terms, and on how a data vendor selects its representative contract.

Continuous futures series should identify how and when the vendor changes its representative contract. A fixed-date roll, a volume-based roll and an open-interest-based roll can produce different time series.

Factors That Affect Calendar Spreads

The price difference between contract months can be affected by financing, storage and insurance costs, deliverable inventory, contract liquidity and convenience yield.

A simplified cost-of-carry model can illustrate the concept, but it does not precisely predict an observed market spread. An interest rate alone is not sufficient to determine either its direction or magnitude.

A spread for a particular date should be calculated from exchange prices for the two contract months recorded at the same time.

This Site's Benchmark Does Not Roll Between Futures Months

GoldSilver Tracker uses a vendor-supplied aggregated USD spot observation rather than a specified COMEX futures month. The dashboard benchmark therefore does not switch from a February contract to an April contract.

The name comex may remain in internal routes and cache keys for compatibility, but the displayed benchmark is not a specified settlement price or a continuous futures series.

A daily change in a regional premium on this site should not automatically be attributed to a futures roll. The price source, timestamp, exchange rate, market closure and data status should be checked first.
