SIZ8 last trading day: December 27, 2028

The date that matters on SIZ8

The first notice day of SIZ8 is November 30, 2028, the last business day of the month preceding delivery. Senzoukria anchors its roll two business days earlier, on November 28, 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.

SIZ8 itself keeps quoting until its official last trading day, December 27, 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 SIZ8 as the default contract on November 24, 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.

SIZ8 is the last 2028 delivery listed for SI, so the volume moves into the first 2029 contract.

What one tick is worth on SIZ8

The minimum price fluctuation is 0.005, which is $25.00 per contract on a multiplier of 5000. A full point is therefore $5,000.00. 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 SI 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 SIZ8 position and the rows of its footprint come from the same numbers.

Every SI delivery listed in 2028
