Futures rollover, contango, and backwardation

A futures position has a contract month. A continuous chart has a stitching rule. Those are related, but they are not the same object, and a signal record should keep the difference visible.

What rollover means

Rollover is the process of moving exposure from an expiring or less-active contract into a later contract. A provider may roll on a calendar date, when volume changes, when open interest changes, or when a model's own rule says the active contract has changed. The convention should be declared before the result is measured.

Record the old contract, the close or transfer price, the new contract, the opening price, the timestamp, the spread, and any price adjustment used for charting. Treat the roll as a separate event. If it is hidden inside a continuous line, a buyer cannot tell whether a reported move came from the underlying market or from the stitching method.

Contango and backwardation

Contango describes a term structure in which a later contract is priced above an earlier contract under the relevant comparison. Backwardation describes the reverse relationship. These terms do not automatically predict a profit or loss for a specific trade. They describe the relationship between contract months and help explain why a continuous series can diverge from the result of holding a particular contract.

The roll difference can be economically meaningful. A signal provider should not call it a market return without stating whether the result is based on one listed contract, a rolled position, a back-adjusted series, or a theoretical continuous instrument.

Continuous charts are analytical tools

Continuous charts can be built by joining contracts at a roll boundary, using raw prices, ratio adjustments, difference adjustments, or other conventions. Each choice changes the visual history. A back-adjusted chart may remove a visible jump for analysis, but the adjustment is not cash received by a live account. A signal record can use a continuous series, but it should call it a research series and show how the active contract was selected for execution.

Rollover questions for every service

• Which contract was actually traded at each signal timestamp?
• What event triggers the roll: date, volume, open interest, or another rule?
• Are signals paused during the hand-off or carried through?
• How are the old and new fills, spreads, and fees recorded?
• Does the performance chart use raw, back-adjusted, or theoretical prices?

The contract identity guide covers the fields a call should publish. The settlement guide covers another common mismatch between a chart and a live account.

How rollover affects a track record

A clean record does not need to avoid all rolls. It needs to show them consistently. A buyer should be able to distinguish a normal signal exit from a roll, see whether the same risk budget was maintained, and identify whether the provider closed one contract before opening another. A record that changes its roll convention after the outcome is known is not comparable with a record whose convention was fixed in advance.

Bottom line

Rollover is not a technical footnote. It is the point where contract identity, price series, liquidity, and execution meet. A trustworthy futures signal names that boundary before the result is reported.
