Understanding Futures Contracts and Trading Mechanics

A futures contract is a standardized financial derivative agreement to buy or sell a underlying asset (commodities, equity indices, currencies, or interest rates) at a predetermined price on a specified future date.

Key Concepts in Futures Trading

• Contract Size & Multiplier: The standard quantity of the underlying asset governed by a single contract (e.g., 100 troy ounces for Gold futures, 5,000 bushels for Corn).
• Notional Value: The total market value controlled by the position. Calculated as: $$\text{Notional Value} = \text{Futures Price} \times \text{Contract Size} \times \text{Number of Contracts}$$
• Initial Margin: The minimum amount of capital required by the broker to open a leveraged futures position.
• Leverage: Because futures require only a fraction of the notional value as margin, small price changes produce amplified gains or losses relative to the committed margin capital.

Calculating Futures Profit and Loss (PnL)

The profit or loss on a futures trade depends on whether you hold a long (buy) or short (sell) position:

$$\text{Long PnL} = (\text{Exit Price} - \text{Entry Price}) \times \text{Total Contract Units}$$

$$\text{Short PnL} = (\text{Entry Price} - \text{Exit Price}) \times \text{Total Contract Units}$$

The return on initial margin (ROI) is determined by:

$$\text{ROI (\%)} = \left( \frac{\text{PnL}}{\text{Initial Margin}} \right) \times 100$$
