GCM8 last trading day: June 28, 2028

The date that matters on GCM8

The first notice day of GCM8 is May 31, 2028, the last business day of the month preceding delivery. Senzoukria anchors its roll two business days earlier, on May 29, 2028.

This date is not the last trading day. A metal contract keeps quoting into its delivery month, but past the first notice day it is deliverable, liquidity collapses, and most brokers and prop firms liquidate what is left. Senzoukria therefore anchors its roll two business days before the first notice day and never offers a contract already in its delivery period.

GCM8 itself keeps quoting until its official last trading day, June 28, 2028, the third-to-last business day of its delivery month, but that session sits inside the delivery period and is not where the volume is.

Senzoukria stops offering GCM8 as the default contract on May 25, 2028, 4 calendar days before that roll anchor, 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

Metal contracts stay quoted into their delivery month, but the volume leaves before the first notice day. The active month is rarely the one whose name matches the calendar, so checking the date rather than the month name is the habit that avoids trading a dying contract.

For GCM8 the next listed delivery is GCQ8, whose roll anchor is July 27, 2028. That is the contract the volume moves into, just as it moved out of GCJ8 on March 25, 2028.

What one tick is worth on GCM8

The minimum price fluctuation is 0.1, which is $10.00 per contract on a multiplier of 100. A full point is therefore $100.00. 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 0.1 sets how finely the bid and ask volume of GC 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 GCM8 position and the rows of its footprint come from the same numbers.

Every GC delivery listed in 2028

GC lists 6 delivery months a year (G, J, M, Q, V, Z). GCM8 is number 3 of 6 in 2028.

GCM8 and MGCM8 side by side

GC and MGC track the same underlying, but GC is 10 times the size of MGC: $10.00 a tick against $1.00. Both quote on the same 0.1 tick. GCM8 and MGCM8 share the same roll anchor, May 29, 2028, so a position in either rolls on the same date.

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