6BZ8 expiry: December 18, 2028

When 6BZ8 stops trading

Trading terminates at 9:16 a.m. CT on the second business day immediately preceding the third Wednesday of the contract month. For 6BZ8 that falls on December 18, 2028.

Senzoukria stops offering 6BZ8 as the default contract on December 14, 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

Currency futures roll quarterly, and the open interest moves in the days around the roll rather than on the last trading day. The expiring month keeps quoting until delivery, but its book is too thin to read an auction on.

6BZ8 is the last 2028 delivery listed for 6B, so the volume moves into the first 2029 contract.

What one tick is worth on 6BZ8

The minimum price fluctuation is 0.0001, which is $6.25 per contract on a multiplier of 62500. A full point is therefore $62,500.00. 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 0.0001 sets how finely the bid and ask volume of 6B 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 6BZ8 position and the rows of its footprint come from the same numbers.

Every 6B delivery listed in 2028

6B lists 4 delivery months a year (H, M, U, Z). 6BZ8 is number 4 of 4 in 2028.

6BZ8 and M6BZ8 side by side

6B and M6B track the same underlying, but 6B is 10 times the size of M6B: $6.25 a tick against $0.63. Both quote on the same 0.0001 tick. 6BZ8 and M6BZ8 share the same last trading day, December 18, 2028, so a position in either rolls on the same date.

The practical difference is position sizing rather than behaviour. M6B lets a 10-contract position carry the same exposure as one 6B, which makes partial exits possible on a small account; 6B carries the deeper book, so its footprint and its depth of market are the ones to read even when the position is held in M6B.
