3. What are the Key Components of a Futures Contract?

Futures contracts are standardized trading instruments that allow participants to buy or sell an asset at a predetermined price on a future date. These contracts are carefully structured by the exchange to ensure transparency, uniformity, and risk control.

To trade futures effectively, it’s essential to understand the key components that define every contract. Each component plays a role in how the contract behaves in the market and impacts a trader’s strategy, risk, and returns.

1. Underlying Asset

This is the base asset that the futures contract derives its value from. It could be:

The price of the futures contract moves based on the spot price (current market price) of this asset.

2. Contract Size (Lot Size)

This defines the quantity of the underlying asset covered by a single futures contract. The lot size is fixed by the exchange.

Examples:

The lot size determines the capital required and the profit or loss per point movement.

3. Expiry Date

Futures contracts have a limited life. Each contract has a monthly expiry, usually the last Thursday of the month.

After this date, the contract becomes invalid, and positions must either be:

4. Tick Size

The tick size is the minimum price movement allowed in the contract.

Example:

Each tick represents a small monetary change, which when multiplied by the lot size determines the gain or loss for that movement.

5. Margin Requirement

You don’t need to pay the full value of the contract. Instead, you deposit a percentage of the total value as margin—this allows leverage.

Margins are usually between 5% to 15% of the contract value and include:

6. Settlement Type

Futures contracts can be settled in two ways:

The type of settlement depends on the asset and exchange rules.

7. Contract Value

This is the total value of the futures position.

Contract Value = Lot Size x Future Price

Example:

8. Mark-to-Market (MTM)

This refers to the daily settlement of gains or losses based on the current market price of the contract.

MTM ensures that positions are regularly adjusted, and traders must maintain enough balance to avoid a margin call.
