CLM8 expiry: May 22, 2028

When CLM8 stops trading

Trading terminates 3 business days prior to the 25th calendar day of the month prior to the contract month. If the 25th is not a business day, trading terminates 3 business days prior to the last business day preceding the 25th. For CLM8 that falls on May 22, 2028.

Senzoukria stops offering CLM8 as the default contract on May 18, 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

Energy contracts expire monthly, so the roll is a routine of every month rather than every quarter. Volume leaves the expiring month several sessions before its last trading day, and the spread between the two months widens as it does.

For CLM8 the next listed delivery is CLN8, whose last trading day is June 20, 2028. That is the contract the volume moves into, just as it moved out of CLK8 on April 16, 2028.

What one tick is worth on CLM8

The minimum price fluctuation is 0.01, which is $10.00 per contract on a multiplier of 1000. A full point is therefore $1,000.00. 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 0.01 sets how finely the bid and ask volume of CL 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 CLM8 position and the rows of its footprint come from the same numbers.

Every CL delivery listed in 2028

CL lists 12 delivery months a year (F, G, H, J, K, M, N, Q, U, V, X, Z). CLM8 is number 6 of 12 in 2028.

CLM8 and MCLM8 side by side

CL and MCL track the same underlying, but CL is 10 times the size of MCL: $10.00 a tick against $1.00. Both quote on the same 0.01 tick. CLM8 and MCLM8 share the same last trading day, May 22, 2028, so a position in either rolls on the same date.

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