Notice Period

A notice period is the stretch of time before a futures contract's expiration during which a seller who is still holding a contract can formally notify the exchange (and, in turn, the buyer) that they intend to make physical delivery of the underlying commodity or asset, rather than simply closing out the position.

Futures contracts were originally built for physical delivery: one side agrees to deliver a set quantity of something (say, wheat, crude oil, or a currency) and the other side agrees to accept it. As the contract approaches expiration, exchanges open a window — the notice period — in which a short (the seller) can file a "notice of intent to deliver." Once that notice is issued, the buyer holding the matching contract can actually be assigned the delivery obligation, meaning they may end up owning barrels of oil or bushels of corn instead of a paper contract.

The nuance that trips people up is that notice periods matter mostly to traders who are actually still holding a contract close to expiration. Most day traders and even most swing traders never touch this stage at all, because financially-settled contracts (like most stock index futures) don't involve physical delivery in the first place, and traders in deliverable contracts (like crude oil or agricultural futures) typically close or roll their positions well before the notice period begins specifically to avoid being on either side of a delivery. Brokers also frequently force-close retail accounts ahead of notice periods for exactly this reason.

The length and start date of a notice period is set by each exchange for each contract, and it varies by product — it is not a single fixed rule that applies to all futures.
