Futures rollover means moving trading activity from one contract month to a later one. If you hold a position, rolling involves closing the old contract and opening the later contract. If you are flat, switching the chart alone is not enough: check the order ticket, working orders and the prop firm's permitted symbols too.
This guide explains exchange-traded futures, not a CFD broker's overnight financing charge. Official CME educational references were reviewed September 18, 2026.
Separate expiry from your rollover decision
A futures contract has a limited lifespan. CME explains that traders can offset a position, roll into a later month, or allow the contract to reach settlement. The settlement method depends on the product. Trading volume in the expiring and later contracts can inform when traders switch. Source: CME on expiration and contract roll.
An exchange expiration date is not automatically the last date your prop firm permits that contract. Record the firm's cutoff separately. This article does not supply a universal rollover date or imply that a simulated account can hold a contract into delivery.
Read the complete symbol
Contract identifiers contain a product code and information about the expiration month and year. Formats can differ between platforms. Common quarterly month letters are:
| Letter | Contract month |
|---|---|
| H | March |
| M | June |
| U | September |
| Z | December |
CME's contract-code guide explains these identifiers. Read the platform's full contract description and year rather than relying on a familiar root symbol alone.
For example, a watchlist label that only displays the product name can conceal the distinction between two expirations. Expand the description before using it as the source for an order.
A flat trader's switching checklist
A trader who closes every position before the session cutoff may not need to execute a spread to roll a position. The task can instead be updating the workspace for the next trading session.
| Workspace item | Verify | Example of an avoidable mismatch |
|---|---|---|
| Analysis chart | Exact product, month and year | Chart shows later month; ticket still shows old month |
| Order ticket | Instrument and account selection | Correct contract, wrong evaluation account |
| Working orders | Instrument attached to every remaining order | Old-contract entry remains active |
| Watchlist | Labels distinguish expirations | Two rows look identical |
| Alerts | Underlying instrument and price levels | Alert remains attached to the old contract |
| Trading journal | Contract used for each fill | Results combine different months without labels |
This is a preparation checklist, not a statement that every platform handles rollover the same way. Confirm each setting in the interface used for the actual account.
If a position is open, a chart change does not close it
CME describes a position roll as offsetting the existing contract and establishing exposure in a later one. A hypothetical trader long one old-month contract would close that long and establish the intended position in the later month.
Before doing so on a prop account, check whether that order sequence, any temporary spread exposure and the selected expirations are permitted. Do not assume a chart's automatic rollover feature performs the necessary account transactions. Inspect actual positions and order confirmations.
Do not count a month-price difference as free profit
Suppose the old contract is quoted at 6,000 and the later contract at 6,012. These are hypothetical prices, not current market quotes. The 12-point difference is between two instruments. It is not automatically 12 points earned by changing the chart.
A useful journal keeps the closing transaction and opening transaction separate:
| Journal field | Old month | Later month |
|---|---|---|
| Instrument | Exact expiring contract | Exact replacement contract |
| Action | Record actual closing fill | Record actual opening fill |
| Costs | Fees associated with closing | Fees associated with opening |
| Exposure | Confirm old position is closed | Confirm intended new position |
Calculate realized results from actual entry and exit fills for the same contract. Do not compare two unrelated displayed prices as though they were a completed trade.
Recheck the instrument before reusing trade settings
Saved quantity, stop distance and dollar-risk assumptions deserve another check when the workspace changes. Confirm that the new selection is the same product size, not a similarly named micro or mini contract.
For a separate explanation of contract-size risk, see the MES versus MNQ position-sizing guide. Rollover is about the expiration month; position sizing is about exposure. They solve different problems.
Finish with a clean-state review
Before the next order, confirm the old position is closed when intended, unwanted working orders are canceled, the selected contract is permitted, and the order ticket matches the analysis chart. Save the full symbol in the journal.
If the firm's permitted-contract list or cutoff is unclear, resolve that specific point before trading. A general exchange calendar explains the contract lifecycle but does not replace the rules attached to the prop account.
