Futures daily price limits set the permitted trading range for a contract during a session, shaping where orders may execute and whether trading may pause or expand. They do not guarantee that an order will execute at the boundary. Depending on the product rules, a limit move can leave orders queued, pause trading, widen the range, or end trading for the day.
How the permitted range is set
The exchange publishes product-specific limits and the reference price used to calculate them. A limit might be stated as a fixed number of index points, cents per bushel, dollars per unit, or another measure appropriate to the contract. The exchange can also publish special rules for delivery months, related contracts, or periods of exceptional volatility.
Do not infer today’s limit from yesterday’s chart. The applicable range may depend on the settlement price, a prior limit move, the contract month, or an exchange notice. The CME Group price-limits page is the starting point for the current product tables and rule references.
| Term | What it means | What it does not mean |
|---|---|---|
| Daily price limit | The maximum permitted trading range for the session | A guaranteed execution price |
| Limit up | The upper boundary is active | Every buy order will fill |
| Limit down | The lower boundary is active | Every sell order will fill |
| Expanded limit | A wider range applies under the product rules | All contracts expand automatically |
What happens when the contract reaches a limit?
The answer comes from the product rule. CME’s overview lists several possible actions: a temporary halt, an expansion of the allowed range, a continuing limit condition, or an end to trading for the day. Related contract months can also be affected. That is why “the market hit limit” is only the beginning of the explanation.
A contract can be quoted at the boundary without much executable liquidity. If many market participants want to trade in the same direction, orders can queue while few counterparties are willing or permitted to take the other side. The displayed price may therefore understate the difficulty of closing a position.
What a limit move means for your orders
A market order does not override the limit. It can remain unfilled until an eligible counterparty appears or the permitted range changes. A stop order can be triggered yet still execute later and at a materially different price. A limit order protects its stated price, but it may not execute at all.
Review the mechanics in our futures order types guide. If the contract is approaching expiration, also check how futures expiration works; delivery-month rules and thinning liquidity can change the practical risk.
A practical risk checklist
- Open the exchange’s current product table and contract rule before the session.
- Identify the reference price, the initial range, and any expansion sequence.
- Check whether related months or options are subject to linked rules.
- Assume an exit can be delayed when the market is locked at a boundary.
- Size the position for a move beyond one day’s limit, not only for the visible range.
- Know your broker’s liquidation, margin-call, and order-handling policies.
Price limits and margin are separate controls. The exchange or broker may raise margin during volatile conditions even when the permitted price range has not changed. Our guide to initial versus maintenance margin explains the account side of that risk.
Common questions
Can I close a position at limit up or limit down?
Only if an eligible order on the other side is available and the contract rules allow the trade. The boundary itself does not guarantee liquidity.
Does a limit move mean the market is closed?
Not always. Depending on the contract, trading may continue at the boundary, pause temporarily, reopen with expanded limits, or stop for the session.
Are all futures subject to the same limits?
No. Limits and their consequences are product specific, and some contracts use different volatility controls. Check the current exchange material for the exact symbol and contract month.
