When RBX9 stops trading

Trading terminates on the last business day of the month preceding the delivery month. For RBX9 that falls on October 31, 2029.

Senzoukria stops offering RBX9 as the default contract on October 27, 2029, 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 RBX9 the next listed delivery is RBZ9, whose last trading day is November 30, 2029. That is the contract the volume moves into, just as it moved out of RBV9 on September 24, 2029.

What one tick is worth on RBX9

The minimum price fluctuation is 0.0001, which is $4.20 per contract on a multiplier of 42000. A full point is therefore $42,000.00. 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 0.0001 sets how finely the bid and ask volume of RB 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 RBX9 position and the rows of its footprint come from the same numbers.

Every RB delivery listed in 2029

RB lists 12 delivery months a year (F, G, H, J, K, M, N, Q, U, V, X, Z). RBX9 is number 11 of 12 in 2029.
