RB Futures (RBOB Gasoline): Tick Value, Expiries, Order Flow

RB contract specifications

The contract unit is 42,000 gallons, quoted in U.S. dollars and cents per gallon. The minimum fluctuation is $0.0001 per gallon, so one tick is worth $4.20 and a one-dollar move $42,000 per contract. It is settled by physical delivery. Senzoukria's contract table holds the same tick and multiplier on the NYMEX venue code.

RB last trading day and next contracts

Trading ends on the last business day of the month preceding the delivery month.

RBV6, the October contract, trades until September 30, 2026, so on September 25 it is still Senzoukria's front month. For RBV6, the default moves to the next listed month on September 26, 2026 (4 calendar days before September 30, 2026), and RBV6 stays selectable with its badge until that date.

RB tick value and P&L arithmetic

• One tick = $0.0001 × 42,000 = $4.20.
• 10 ticks ($0.001 per gallon) = $42 per contract.
• A $0.05 stop is 500 ticks: $2,100 per contract, $4,200 on 2 contracts.
• The same $0.05 on HO is $2,100 per contract.

Reading RB order flow

With row resolution off, an RB footprint has one row per $0.0001 tick and prices carry 4 decimals. The fixed steps give 2 ticks = 0.0002, 4 ticks = 0.0004, 8 ticks = 0.0008, 16 ticks = 0.0016, 32 ticks = 0.0032 dollars per gallon per row.

RBOB, in the rulebook's words a reformulated gasoline blendstock for blending with 10% denatured fuel ethanol, is quoted in dollars per gallon with a tick of $0.0001, worth $4.20 on 42,000 gallons, so a one-cent move is 100 ticks and $420. RB and HO share the gallon unit and the tick, which makes their dollar arithmetic identical, but their books and tapes are separate.
