ZWU8 expiry: September 14, 2028

When ZWU8 stops trading

Trading terminates on the business day preceding the 15th calendar day of the contract month. For ZWU8 that falls on September 14, 2028.

Senzoukria stops offering ZWU8 as the default contract on September 10, 2028, 4 calendar days before that last trading day, and keeps it selectable with a badge. The date is computed from the exchange rule rather than stored. The engine counts Monday to Friday and holds no CME holiday table, so a date that falls next to a public holiday can be one day off the exchange calendar. Check the exchange calendar when the date sits close to a holiday.

When the volume actually leaves

Grain contracts follow the crop calendar rather than the quarter, so the listed months are uneven and the roll dates do not fall at regular intervals. The active month is the one carrying the volume, not the nearest by date.

For ZWU8 the next listed delivery is ZWZ8, whose last trading day is December 14, 2028. That is the contract the volume moves into, just as it moved out of ZWN8 on July 10, 2028.

What one tick is worth on ZWU8

The minimum price fluctuation is 0.25, which is $12.50 per contract on a multiplier of 50. A full point is therefore $50.00. On a footprint chart one row is one tick, so the same vertical space holds a different number of rows depending on the product: a tick of 0.25 sets how finely the bid and ask volume of ZW can be read.

These are the values the app itself trades on, taken from its contract table rather than retyped, so the P&L shown on a ZWU8 position and the rows of its footprint come from the same numbers.

Every ZW delivery listed in 2028

ZW lists 5 delivery months a year (H, K, N, U, Z). ZWU8 is number 4 of 5 in 2028.
