ZRK8 expiry: May 12, 2028

When ZRK8 stops trading

Trading terminates on the business day preceding the 15th calendar day of the contract month. For ZRK8 that falls on May 12, 2028.

Senzoukria stops offering ZRK8 as the default contract on May 8, 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 ZRK8 the next listed delivery is ZRN8, whose last trading day is July 14, 2028. That is the contract the volume moves into, just as it moved out of ZRH8 on March 10, 2028.

What one tick is worth on ZRK8

The minimum price fluctuation is 0.005, which is $10.00 per contract on a multiplier of 2000. A full point is therefore $2,000.00. 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 0.005 sets how finely the bid and ask volume of ZR 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 ZRK8 position and the rows of its footprint come from the same numbers.

Every ZR delivery listed in 2028

ZR lists 6 delivery months a year (F, H, K, N, U, X). ZRK8 is number 3 of 6 in 2028.
