Constructing futures rolls ahead of first notice day

First notice day as a construction deadline

Physically settled futures are written against a deliverable commodity, so they list both a first notice day and a last trading day. A physically settled long can be assigned a delivery notice beginning on first notice day, and notices can be issued at any time from that session through last trading day.

Cash-settled futures expire into an account debit or credit rather than a cash-market transfer of the underlying, so only last trading day applies. First notice day is listed only when the contract can transfer the underlying in the cash market.

Editorial reading: treat first notice day as the construction deadline for the flatten or contract-roll, not as the session in which to start looking for an exit.

Assignment, leftover interest, and settlement type

Delivery assignment is described as starting with the longest-held long positions and then proceeding through remaining long interest.

On last trading day the contract stops trading at the session close. Leftover physically settled positions enter delivery. Leftover cash-settled positions are settled in cash the next day at the exchange settlement.

A listed corn futures purchase is described as an agreement to take delivery of the grain unless the long offsets before being forced to accept delivery.

Offset rules before the notice window

Longs are required to offset by the close of the session before first notice day. Shorts that remain after that date still avoid forced delivery if they offset by the close on last trading day.

Late-life futures are described as prone to sudden, irregular volatility into first notice day and last trading day. The material treats a roll completed at least two days earlier as a way to stay out of that window.

Construct the flatten or roll as an executable order

Editorial reading: build the flatten or contract-roll while two-sided volume still supports a volume-weighted-average-price exit. Use that average as an execution filter only while the order book, spread, and remaining session volume still make the ticket implementable.

Implementation cost is the spread, fee, and forced-process expense that rises if a long is assigned or if an offset is delayed into the notice-to-expiry window. Delaying the offset into that window is how a construction problem becomes a delivery-cost event.

Chart tests for leftover exposure

Editorial reading: volume-price analysis compares late-life OHLC structure with volume to test whether the move is still a repeatable chart condition or already a contract-expiry frenzy. Nearby support and resistance frame a falsifiable hypothesis about whether residual exposure should still be held inside the notice window.

Those chart tests do not extend the construction deadline. If the book can no longer support an implementable volume-weighted-average-price offset, leftover price action is already a liquidity and delivery-cost event.
