Formula Breakdown

The Gate.io contract calculation formula consists of several key parameters:

• Contract Price: The current price of the underlying asset (e.g., BTC, ETH) at which the contract is trading.
• Contract Size: The notional value of each contract, expressed in the underlying asset (e.g., 1 BTC, 100 ETH).
• Leverage: The amount of capital provided by the exchange to amplify the trader's position (e.g., 10x, 20x).
• Position: The trader's open position size, measured in contract units (e.g., 0.1 BTC, 5 ETH).
• P&L: The profit or loss (realized or unrealized) on the trader's position, expressed in the settlement currency (e.g., USDT).

Step-by-Step Calculation Process

Determining Contract Value

To calculate the value of a contract, multiply the contract price by the contract size:

Contract Value = Contract Price x Contract Size

For example, if the contract price is $10,000 and the contract size is 0.1 BTC, the contract value would be 0.1 BTC x $10,000 = $1,000.

Accounting for Leverage

Leverage amplifies both the potential profits and losses on a contract position. The trader's exposure to the market is multiplied by the leverage factor:

Exposure = Contract Value x Leverage

Continuing with the previous example, if the leverage is 10x, the trader's exposure would be $1,000 x 10 = $10,000.

Computing Profit or Loss

The P&L is calculated based on the difference between the current contract price and the entry price, multiplied by the position size and leverage:

P&L = (Current Contract Price - Entry Price) x Position Size x Leverage

Suppose the trader bought 0.1 BTC contract at a price of $9,000, and the current contract price is $9,500. With a leverage of 10x, the P&L would be ($9,500 - $9,000) x 0.1 x 10 = $500.

Note: The P&L can be positive (profit) or negative (loss), depending on the direction of the contract price movement.

Other Considerations

• Margin: The margin is the amount of funds required to maintain the contract position. It is calculated as a percentage of the contract value.
• Mark Price: The mark price is the exchange's estimated fair value of the underlying asset. It is used to prevent market manipulation and liquidation triggers.
• Funding Fee: Funding fees are paid or received by traders based on the funding rate, which adjusts the contract price to match the spot price.
