Futures Contracts Explained

Original Delta-X illustration.
free9 min read

A futures contract is a standardised, exchange-traded agreement to buy or sell a fixed quantity of an underlying asset at a set future date, with terms, contract size, tick increment, and expiry, defined by the exchange rather than negotiated. Traders rarely hold to delivery; they trade the contract's price movement and close or roll before expiry.

Target audience: Traders moving toward index or commodity futures, including prop-firm candidates, who need the contract mechanics.

Definition

A futures contract is a standardised, exchange-traded agreement to buy or sell a fixed quantity of an underlying asset at a set future date, with terms, contract size, tick increment, and expiry, defined by the exchange rather than negotiated. Traders rarely hold to delivery; they trade the contract's price movement and close or roll before expiry.

Why it matters

Futures are the instrument many prop firms and active index and commodity traders use, so understanding their fixed contract sizes, expiry and roll, and centralised structure is essential before trading them. Their standardisation makes costs and sizes predictable, but the fixed contract value and built-in leverage also mean a single contract can carry far more exposure than a beginner expects.

A standardised, exchange-traded contract

Unlike a privately negotiated deal, a futures contract has its terms fixed by the exchange: the underlying, the contract size or multiplier, the minimum price increment (the tick), and the expiry date are all standardised. This standardisation is why futures are liquid and why costs and sizes are predictable; every participant trades the same defined contract. Trades are centrally cleared through the exchange's clearing house, which stands between buyer and seller, a structure that differs from the decentralised, broker-faced nature of some other markets.

Expiry, delivery, and the roll

Every futures contract has an expiry, and in principle it settles by delivery of the underlying or by cash at that date. Active traders almost never want delivery; they trade the price movement and so must close the position, or roll it to the next contract month, before expiry. Rolling means closing the expiring contract and opening the equivalent in a later month, which carries its own small cost and a price difference between months. Ignoring expiry is a beginner error: a position left open into expiry can settle in ways you did not intend.

Fixed contract size and built-in leverage

Each contract represents a fixed amount of the underlying through its multiplier, so its value, and the money at stake per point of movement, is set by the contract, not chosen freely. Because you post only a margin deposit to control that full contract value, futures are inherently leveraged, and a single standard contract can carry more exposure than a small account can responsibly hold. This is why exchanges also list smaller versions, such as micro contracts at a fraction of the size, which let smaller accounts take proportionate risk. Knowing the contract value before trading is non-negotiable.

Worked examples

Example 1: The contract that was too big

A trader with a small account buys one standard index future, drawn by the clean chart, without checking the contract value. A modest, ordinary move against them translates, through the contract multiplier, into a loss that is a large fraction of their account, because one standard contract controlled far more exposure than the account could absorb. Had they checked the contract value first and traded a micro version sized to their account, the same adverse move would have been a small, routine loss. The chart was fine; the contract size was the risk they had not measured.

Common mistakes

Trading a standard contract without checking its full value and exposure.

Leaving a position open into expiry instead of closing or rolling.

Forgetting that futures are leveraged because you post only margin.

Assuming a small account can responsibly hold a standard contract.

Ignoring the small cost and price difference involved in rolling.

Myth vs reality

Myth

That you must take delivery of the underlying if you hold a future.

Reality

No paired reality note provided.

Myth

That contract size is something you choose freely rather than a fixed spec.

Reality

No paired reality note provided.

Myth

That futures are unleveraged because no money is borrowed explicitly.

Reality

No paired reality note provided.

Risk considerations

  • A single standard contract can carry far more exposure than a small account should hold.
  • A position left into expiry can settle in unintended ways.

Practice exercises

1. Read a contract spec

Look up the specification of one futures contract you might trade and note what it commits you to.

  1. Find the contract's multiplier and the value of a one-point move.
  2. Note its tick size and what one tick is worth.
  3. Find its expiry and the typical roll date.
  4. Check whether a smaller (micro) version exists for your account size.

Contract specifications, leverage limits, costs, and availability vary by broker, exchange, and jurisdiction, and some instruments are restricted or banned for retail traders in some regions; any figures here are illustrative, so verify the exact specs with your own provider. Leverage amplifies losses as much as gains and can result in losing more than your initial deposit. Markets carry substantial risk. Trade only with risk you can afford to lose.
