What Is Futures Trading? A Guide to How Futures Contracts Work

Key Takeaways

• Standardized contracts: A futures contract is an agreement to buy or sell an asset at a set price on a future date. Exchanges fix the contract size, expiry and tick value, so every trader trades the same product.

• Margin and leverage: Traders post a fraction of the contract’s value as margin, which allows large exposure for a small deposit. Leverage magnifies both gains and losses.

• Daily settlement: Positions are marked to market every day, so profits and losses are credited or debited to the account daily, and margin calls can follow quickly.

• Two main uses: Hedgers use futures to protect against unfavorable price moves, while speculators aim to profit from them. Futures cover commodities, stock indices, currencies and interest rates.

What Is a Futures Contract?

A futures contract is a standardized agreement to buy or sell an asset, such as oil, gold or a stock index, at a set price on a specific future date. Traded on regulated exchanges, futures are used to hedge price risk or speculate on price movements, usually with margin.

The asset a contract is based on is called the underlying. Because the exchange standardizes the terms, futures can be bought and sold easily before expiry, and most traders close their positions without ever taking or making delivery of the underlying asset.

How Does Futures Trading Work?

Futures trading starts with choosing a contract, then buying (going long) if you expect the price to rise, or selling (going short) if you expect it to fall. You deposit margin, your position is revalued every day, and you either close it before expiry or roll it into a later contract. The four concepts below explain the mechanics.

Contract Size and Tick Value

Each futures contract represents a fixed quantity of the underlying asset. The tick is the smallest price movement allowed, and the tick value is what one tick is worth in cash for one contract. Knowing both lets you calculate profit and loss before you trade. The values below are examples from major CME Group contracts; always check the exchange’s current specifications.

Margin and Leverage in Futures

Futures margin is not a down payment or a loan. It is a performance deposit that shows you can cover potential losses. Initial margin is the amount required to open a position, and maintenance margin is the minimum balance you must keep while it is open. Margin is typically a small percentage of the contract’s full value, which creates leverage: a modest price move can produce a large gain or loss relative to the money in your account. Exchanges and brokers can raise margin requirements, especially in volatile markets.

Expiry Dates and Rollover

Every futures contract has an expiry date, after which it stops trading. Contracts are listed in set monthly or quarterly cycles, such as March, June, September and December for many equity index futures. Some contracts are cash-settled, meaning the difference is paid in cash at expiry. Others are physically settled, meaning the underlying asset is delivered. Most speculative traders avoid settlement by closing the position beforehand or by rolling over, which means closing the expiring contract and opening the same position in a later one. Because the two contracts can trade at different prices, rolling can affect your results.

Mark-to-Market and Daily Settlement

At the end of each trading day, the exchange sets a settlement price. Your account is then credited or debited by the difference between that price and the previous day’s. This process, called mark-to-market, means gains and losses are realized in cash every day instead of only when you close the position. If losses push your balance below the maintenance margin, you will receive a margin call and must add funds or reduce the position. If you do not, the broker may close it for you.

Types of Futures Markets

Futures exist on a wide range of underlying assets. The main categories are below.

• Commodities: These include energy, metals and agricultural products. Crude oil futures are widely used to trade or hedge energy prices, and gold futures are popular for exposure to precious metals. Explore oil futures and gold futures.

• Indices: Index futures track the performance of a basket of stocks, such as the S&P 500 or Nasdaq-100, and let traders take a view on the broader market without buying each share. Explore index futures.

• Currencies: Currency futures are contracts on exchange rates, such as the euro against the US dollar. They are used by traders and by businesses managing foreign-exchange exposure. Explore currency futures.

• Interest rates: These contracts are based on government bonds or short-term interest rates, and reflect market expectations of future borrowing costs. Explore interest rate futures.

A Futures Trading Example

The numbers below are simplified and for illustration only. Real margin requirements, prices and fees vary and change over time.

Long position: a winning and a losing outcome

Suppose a trader expects the US stock market to rise and buys one E-mini S&P 500 contract at 5,000 points. The contract’s value is 5,000 × $50 = $250,000. Assume the broker requires $12,000 in margin.

• If the index rises to 5,040: The trader gains 40 points × $50 = $2,000, about 17% of the margin deposited.

• If the index falls to 4,960: The trader loses 40 points × $50 = $2,000, the same amount, also about 17% of the margin. A larger fall would mean a larger loss, and a margin call could arrive before the trader chooses to exit.

Short position: a losing outcome

Now suppose a trader expects oil prices to fall and sells one WTI crude oil contract (1,000 barrels) at $80 per barrel. Assume margin of $7,000.

• If oil falls to $77: The trader gains $3 × 1,000 = $3,000.

• If oil rises to $83: The trader loses $3 × 1,000 = $3,000, about 43% of the margin deposited. If the price keeps rising, the loss has no fixed ceiling, because a short position’s potential loss is theoretically unlimited.

In both examples, the account is adjusted every day through mark-to-market, so the trader would see gains or losses in cash each day, not only at exit.

Who Trades Futures and Why?

Two broad groups trade futures: hedgers and speculators.

• Hedgers use futures to lock in a price and reduce uncertainty. For example, an airline might buy oil futures to protect against rising fuel costs, while a farmer might sell wheat futures to secure a price before harvest. A hedger is willing to give up some potential upside in exchange for more predictable costs or revenue.

• Speculators take on price risk in the hope of profiting from it. They do not intend to buy or deliver the underlying asset, and they typically close positions before expiry. Speculators add liquidity to the market, which makes it easier for hedgers to find a counterparty, but they also carry the risk of loss if the market moves against them.

Many market participants also trade futures to gain efficient exposure to an asset class, or to manage portfolio risk.

Risks of Trading Futures

• Leverage risk: A small margin deposit controls a large position, so even modest price moves can cause significant losses relative to your capital.

• Losses beyond your deposit: Losses can exceed the money in your account, and you may owe your broker the shortfall.

• Margin calls: If your balance falls below maintenance margin, you may have to add funds at short notice or have positions closed, often at an unfavorable price.

• Volatility and gaps: Prices can move sharply on economic data, news or geopolitical events, and can gap past your intended exit level.

• Liquidity risk: Some contracts, especially those further from expiry or in smaller markets, may trade thinly, making it harder to enter or exit at a fair price.

• Expiry and delivery risk: Failing to close or roll a position before expiry can result in cash settlement or, for physically settled contracts, delivery obligations.

• Rollover costs: Moving into a later contract can involve price differences and extra transaction costs.

• Complexity: Contract specifications, margin rules and settlement procedures differ by market, so it is essential to understand them before trading.

Futures Trading Explained: The Bottom Line

Futures are standardized, exchange-traded contracts that let participants hedge against price moves or speculate on them. Their key features are fixed contract sizes, margin-based leverage, set expiry dates and daily mark-to-market settlement. Those same features make them efficient, but they also mean losses can build quickly and can exceed your initial deposit. Before trading, make sure you understand the contract specifications, how margin works and how much you can afford to risk. If you are new to futures, practising on a demo account is a sensible way to learn how the mechanics work without risking real capital.

Futures Trading FAQs

Can you lose more than you invest with futures?

Yes. Because futures are leveraged, losses are based on the full value of the contract, not just the margin you deposited. If the market moves sharply against you, your losses can exceed your account balance, and you may be required to cover the shortfall. Using stop orders, smaller contract sizes and careful position sizing can help manage this risk, though they cannot remove it.

What happens when a futures contract expires?

At expiry, the contract is settled either in cash or by physical delivery, depending on its specifications. Cash-settled contracts, such as most stock index futures, are closed out at a final settlement price, with the difference credited or debited to your account. Physically settled contracts, such as many commodity futures, require delivery of the underlying asset. Most traders close or roll their positions before expiry to avoid settlement.

What is the difference between futures and spot prices?

The spot price is the current market price for immediate delivery of an asset. The futures price is the price agreed today for delivery on a future date. The two usually differ because futures prices reflect factors such as interest rates, storage costs and market expectations. As a contract approaches expiry, its price generally converges toward the spot price.

Are futures good for beginners?

Futures can be difficult for beginners because of leverage, margin calls and daily settlement. They are not necessarily unsuitable, but they require education and discipline. Many newer traders start by learning contract specifications, practising on a demo account, and using smaller contracts, such as micro futures, to keep exposure manageable. Only trade with money you can afford to lose.
