RBOB Gasoline Futures Contract Specifications (RB)
Energy futures are physically deliverable and settle against a specific grade at a specific location. Contract size, tick size and the delivery point all matter, because the quoted price refers to that grade at that hub.

Margin is not listed here on purpose — the exchange revises it and every broker adds its own buffer. Check your broker's platform for the live figure. Use the margin calculator to estimate what a position will tie up.
Doing the tick math
One tick is 0.0001 in the quoted price, which is $4.20 per contract. A move of one full point (1.00 in the quoted price) is worth $42,000, so there are 10,000 ticks in a point. Get those two numbers wrong and every risk calculation downstream is wrong, which is the point of the tick value guide.
Enter your own prices in the tick value and P/L calculator to see the dollar result for this contract without doing the arithmetic by hand.
Delivery months
All. Liquidity concentrates in the nearest active month; open interest migrates over a few weeks before expiry, which is what the roll mechanics guide walks through.
What one tick is worth at different position sizes
The per-tick figure scales linearly, which is the part most traders get wrong when they add contracts without re-checking risk.
| Position | Value of 1 tick | Value of 10 ticks |
|---|---|---|
| 1 contract | $4.20 | $42 |
| 2 contracts | $8.40 | $84 |
| 5 contracts | $21 | $210 |
| 10 contracts | $42 | $420 |
Ten ticks on a RB contract is a move of 0.0001 × 10 in the quoted price. If you want the P/L for a specific entry and exit rather than a tick multiple, put the prices into the tick value calculator.
Converting your stop into a dollar risk
Stops are set in price terms but risk is booked in dollars. Multiply the stop distance in ticks by the tick value — and then add commission, which is charged per contract per side and is not in the numbers below.
| Stop distance | 1 contract | 5 contracts |
|---|---|---|
| 5 ticks | $21 | $105 |
| 10 ticks | $42 | $210 |
| 20 ticks | $84 | $420 |
| 40 ticks | $168 | $840 |
On a 42,000 gal contract, a 20-tick stop at one contract ties up $84 of risk before costs. At five contracts it is $420. This is why position size should follow the stop, not the other way round — the arithmetic is laid out in choosing a futures contract.
How margin is set on RBOB Gasoline futures
Margin is not a property of the contract spec — it is a risk parameter the exchange recalculates periodically and that your broker then marks up. Two consequences follow:
- The figure moves when volatility moves, so a margin number copied from a blog post is usually stale.
- Two brokers can require different amounts for the same RB contract.
What is fixed by the spec is the notional exposure: 42,000 gal multiplied by the price. Margin is a percentage of that notional, which is why a higher price or a wider exchange buffer raises the cash requirement without the contract itself changing. The margin calculator takes your broker's number and converts it into "how many contracts can I hold"; the mechanics are in how futures margin works.
Where these numbers come from
Contract unit, tick size and delivery months are taken from the contract specifications published by NYMEX/CME. Exchanges occasionally change tick sizes and listing months, so before relying on this page for a live position, check the current spec sheet on the exchange's own product page or on your broker's platform.
