When ZRK0 stops trading

Trading terminates on the business day preceding the 15th calendar day of the contract month. For ZRK0 that falls on May 14, 2030.

Senzoukria stops offering ZRK0 as the default contract on May 10, 2030, 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 ZRK0 the next listed delivery is ZRN0, whose last trading day is July 12, 2030. That is the contract the volume moves into, just as it moved out of ZRH0 on March 10, 2030.

What one tick is worth on ZRK0

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 ZRK0 position and the rows of its footprint come from the same numbers.

Every ZR delivery listed in 2030

ZR lists 6 delivery months a year (F, H, K, N, U, X). ZRK0 is number 3 of 6 in 2030.
