Lesson 2 of 21

Every futures contract comes with a set of contract specifications, published by the exchange, that define exactly what is being traded. They tell you how big one contract is, how prices are quoted, the smallest price move and its dollar value, which months are listed, when trading stops and how the contract settles. Reading the specifications before trading is essential: two contracts on the same asset can differ by a factor of ten in size.

The main fields#

Listed contractsWhich months trade, and how far out
Trading hoursWhen the contract trades, including overnight sessions
Termination of tradingLast trading day rule

Specifications change from time to time; always check the exchange's current page.

Reading a specification#

Micro and mini contracts#

Exchanges list smaller versions of popular contracts to make them accessible:

  • Micro E-mini equity index futures: one tenth of the E-mini size.
  • Micro WTI crude oil: 100 barrels.
  • Micro gold: 10 troy ounces.
  • Micro Bitcoin and Ether futures on CME.

Smaller contracts let traders size positions more precisely, which matters for risk control. See Position Sizing.

Price limits and circuit breakers#

Some contracts have daily price limits or trading halts. Equity index futures on CME have circuit breakers tied to the S&P 500 market wide halts during regular hours and limits overnight; many agricultural contracts have daily limits that can expand after limit moves. When a market is "locked limit", trading can stop at that price, making it impossible to exit. See Trading Halts and Circuit Breakers.

Why specifications matter#

Common mistakes#

  • Confusing mini and micro contracts.
  • Ignoring the last trading day for physically delivered contracts.
  • Assuming all months are equally liquid.

Frequently asked questions#

What are futures contract specifications?#

The exchange defined terms of a futures contract, including size, price quotation, tick size and value, listed months, trading hours and settlement method.

Where can I find contract specifications?#

On the exchange's website, such as CME Group, ICE or Eurex, under each product's contract specifications page.

What is the difference between E-mini and Micro E-mini futures?#

Micro E-mini contracts are one tenth the size of E-mini contracts, so each tick is worth one tenth as much.

Next, calculate the dollar value of price moves in Tick Size and Tick Value.
