Futures Contracts Basics: What Futures Are and How They Work

Futures are among the oldest and most widely used instruments in financial markets, and in recent years they have become the main vehicle for day traders and prop firm programs. Before opening a first position, it helps to understand exactly what you are buying, how profit and loss are measured, and why leverage cuts both ways. This guide walks through the fundamentals step by step.

What a futures contract is

A futures contract is a binding agreement to buy or sell a specific underlying asset, in a defined quantity, at a price agreed today, on a known future date. The underlying can be a physical commodity such as crude oil, gold or corn, or a financial asset such as a stock index, a bond or a currency.

In practice, most speculative traders never hold a contract until expiration and never take delivery of anything. They close the position beforehand, and their profit or loss comes from the difference between entry and exit prices. Equity index futures such as ES and NQ are cash-settled at expiration anyway, with no physical delivery.

Exchanges and standardization

Futures trade on regulated exchanges, such as those operated by CME Group. The exchange defines every characteristic of the contract in advance, so all contracts of the same type are identical. This standardization is what allows thousands of participants to trade with each other without negotiating every detail.

A contract's specifications usually include:

• The underlying asset and the contract size (multiplier)
• The minimum tick size and its dollar value
• Contract months and expiration dates
• Trading hours
• Settlement method (cash or physical delivery)

Between buyer and seller sits a clearing house, which acts as the counterparty to both sides and reduces the risk that either one fails to meet its obligations. In the United States the market is overseen by the CFTC, and the NFA serves as the industry's self-regulatory organization.

Ticks, tick value and multipliers

A tick is the smallest possible price movement in a contract. Each tick has a fixed dollar value derived from the contract's multiplier. Some well-known examples from CME Group equity index futures:

So a full one-point move in ES is worth $50 per contract, and in NQ it is worth $20 per contract. A hypothetical example: a trader who buys one NQ contract and sees the price rise 10 points makes (before fees) 10 times $20, or $200. If the price falls 10 points, the loss is the same size. The differences between mini and micro contracts are covered in depth in micro vs mini futures.

Specifications can change, so always confirm them on the exchange's website before trading a new contract.

Contract months and expiration

Every futures contract has an expiration date. Several contract months trade at the same time, each identified by a letter code. Equity index futures run on a quarterly cycle: H for March, M for June, U for September and Z for December. The nearest contract, where most trading is concentrated, is usually called the front month.

As the front month approaches expiration, liquidity migrates to the next contract, a process called rollover. It matters especially if you work with automated alerts, and it has its own article: futures contract rollover.

Long and short

In futures it is just as easy to sell as it is to buy:

• Long - buying a contract in the expectation that the price will rise.
• Short - selling a contract in the expectation that the price will fall, without having to borrow anything as you would with stocks.

This symmetry is one reason day traders like futures. It also means risk exists in both directions with equal force.

Leverage and daily settlement

To open a position you do not pay the full notional value of the contract. You post collateral called margin, which is only a small fraction of that value. A hypothetical example: if the Nasdaq-100 stands at 20,000 points, the notional value of one NQ contract is 20,000 times $20, or $400,000. The required margin is far smaller, so a small move in the index has a large effect on the account. That is leverage.

Futures positions are also settled daily (mark-to-market). At the end of each trading day the exchange sets a settlement price, and that day's gain or loss is actually credited or debited to the account. If equity falls below the required level, the broker can demand more funds or close the position. Initial margin, maintenance margin and margin calls are explained in futures margin explained.

Who uses futures

Two main groups participate in the market:

1. Hedgers - businesses or investors with real exposure to the underlying who want to reduce risk. A farmer selling his crop forward, an airline buying fuel futures, or a portfolio manager selling index futures to protect against a decline.
2. Speculators - traders with no interest in the asset itself who try to profit from price movements. They provide liquidity and take on the risk hedgers want to transfer.

Retail traders, day traders and prop firm participants almost always belong to the second group.

Checklist before your first trade

• Read the contract specifications on the exchange's website: multiplier, tick, hours and expiration.
• Work out in advance how many dollars each point and each tick is worth in your chosen contract.
• Decide position size and stop before entering, not during the trade.
• Check which contract month you are trading and when it expires.
• Learn the trading hours and the low-liquidity windows, as described in futures trading sessions.
• Practice in simulation before risking real money.

Key takeaways

• A futures contract is a standardized agreement to buy or sell an underlying asset at a future date, traded on a regulated exchange.
• Profit and loss are measured in ticks and points, and each contract has a fixed multiplier (for example $50 for ES and $20 for NQ).
• Contracts expire on a fixed cycle, which is quarterly for equity index futures.
• Leverage magnifies both gains and losses, and daily settlement makes losses real every day.
• Always verify specifications and requirements with the exchange and your broker.

If you plan to automate your futures trading, WeCore can connect alerts or strategies to your own broker or prop firm account with automated risk controls. It is a good idea to start in simulation mode and confirm everything behaves as expected before moving to a live account.
