Understanding Futures Contracts
A futures contract is a standardized legal agreement to buy or sell a particular commodity, asset, or security at a predetermined price at a specified time in the future. Futures contracts are traded on futures exchanges and are used by speculators to profit from price movements and by hedgers to protect against price volatility.
What is a Futures Contract?
Futures contracts are derivative financial instruments that derive their value from an underlying asset. Unlike options, which give the holder the right but not the obligation to buy or sell, futures contracts obligate both parties to fulfill the terms of the contract at expiration.
Key characteristics of futures contracts include:
- Standardization: Contract specifications (quantity, quality, delivery location, time) are standardized by the exchange
- Margin Trading: Only a fraction of the contract value is required as collateral (margin)
- Daily Settlement: Profits and losses are settled daily (mark-to-market)
- Leverage: Small price movements result in magnified gains or losses
- Liquidity: Major futures markets are highly liquid with tight bid-ask spreads
How to Calculate Futures Profit/Loss
The profit or loss from a futures position is calculated using the following formula:
Profit/Loss = (Exit Price - Entry Price) × (Tick Value / Tick Size) × Number of Contracts
Or equivalently:
Profit/Loss = Number of Ticks × Tick Value × Number of Contracts
For a long position (buying), you profit when the price rises and lose when it falls. For a short position (selling), you profit when the price falls and lose when it rises.
Understanding Tick Size and Tick Value
Two critical concepts in futures trading are tick size and tick value:
- Tick Size: The minimum price movement allowed for a futures contract. For example, the E-mini S&P 500 has a tick size of 0.25 points.
- Tick Value: The dollar value of one tick movement. For the E-mini S&P 500, each tick is worth $12.50.

Futures Contract Month Codes
Futures contracts use specific letter codes to identify the expiration month:
For example, ESZ4 refers to the E-mini S&P 500 contract expiring in December 2024.

Risk Management in Futures Trading
Warning: Futures trading involves substantial risk of loss and is not suitable for all investors. Due to leverage, a small price movement can result in significant losses that may exceed your initial investment. Only trade with capital you can afford to lose.
Key risk management strategies include:
- Position Sizing: Never risk more than 1-2% of your trading capital on a single trade
- Stop-Loss Orders: Always use stop-loss orders to limit potential losses
- Diversification: Don't concentrate all positions in correlated markets
- Understand Margin: Know your margin requirements and maintain adequate account equity
- Monitor Positions: Futures markets can move quickly; monitor positions regularly
Uses of Futures Contracts
- Hedging: Producers and consumers use futures to lock in prices and protect against adverse price movements. For example, a farmer might sell corn futures to lock in a price for their harvest.
- Speculation: Traders attempt to profit from price movements without intending to take delivery of the underlying asset.
- Arbitrage: Traders exploit price differences between related markets or between spot and futures prices.
- Portfolio Management: Institutional investors use futures for asset allocation and risk management.
Frequently Asked Questions
What happens if I hold a futures contract until expiration?
Depending on the contract, you may be required to take physical delivery of the underlying asset (commodity futures) or settle in cash (index futures). Most speculators close their positions before expiration to avoid delivery.
How much money do I need to trade futures?
The initial margin varies by contract. E-mini S&P 500 contracts typically require around $12,000-15,000 in initial margin. However, it's recommended to have significantly more capital to manage risk and avoid margin calls.
What is a margin call?
A margin call occurs when your account equity falls below the maintenance margin requirement. You must deposit additional funds or close positions to meet the requirement, or your broker may liquidate your positions.
Can I lose more than my initial investment?
Yes. Due to leverage, losses can exceed your initial margin deposit. This is why risk management is crucial in futures trading.
