Understanding the Basics of CoinEx Futures Contracts

CoinEx offers a variety of futures contracts, including perpetual contracts and delivery contracts, each with unique characteristics. To calculate profit and loss (PnL) accurately, it’s crucial to understand the contract type you're trading. In perpetual contracts, there's no expiration date, while delivery contracts settle at a predetermined time. The mark price mechanism is used to prevent excessive liquidations and ensure fair pricing on CoinEx. This mechanism calculates the average price across major exchanges to reflect the true market value. Before diving into PnL calculations, traders should also be familiar with funding rates, which are periodic payments exchanged between long and short positions in perpetual contracts.

Key Terminologies for Calculating Profit and Loss

To effectively calculate your profit or loss on CoinEx, certain key terms must be understood:

• Entry Price: The price at which you opened your position.
• Exit Price: The price at which you closed your position.
• Position Size: The number of contracts or units you're trading.
• Leverage: The borrowed capital provided by the exchange to amplify potential returns (or losses).
• Liquidation Price: The price at which your position will be automatically closed to prevent further losses.
• Funding Rate: A recurring fee paid by one side of the market to the other in perpetual contracts.

Understanding these terms allows traders to compute both realized and unrealized gains or losses using basic formulas or automated tools available on the CoinEx platform.

Realized vs. Unrealized Profit and Loss

On CoinEx, realized profit or loss refers to the gain or loss that occurs once a trade is closed. It is calculated based on the difference between your entry and exit prices. Conversely, unrealized profit or loss reflects the current value of an open position relative to its entry price. For example, if you enter a long position at $10,000 with 10x leverage and the price rises to $10,500, your unrealized profit would be calculated based on this movement. However, until you close the position, the profit remains unrealized and can fluctuate with market conditions. Traders should monitor their wallet balance, equity, and available margin to assess their current standing and avoid unexpected liquidation.

Step-by-Step Calculation of Profit and Loss

To manually calculate PnL on CoinEx, follow these steps:

• Determine your position size in USD or the base cryptocurrency.
• Note your entry price and exit price.
• Calculate the price difference between entry and exit.
• Multiply the price difference by the position size to get the gross profit or loss.
• Subtract any fees or funding costs from the result to determine net profit or loss.

For example, if you open a BTC/USDT perpetual contract with a position size of $1,000, entering at $30,000 and exiting at $31,000, the price difference is $1,000. Since BTC contracts are priced per unit, you'd divide your investment by the entry price: $1,000 / $30,000 = ~0.0333 BTC. Then multiply the amount by the price change: 0.0333 $1,000 = $33.33 profit before fees. If the trading fee is 0.02%, you’d deduct $0.20 from the profit, leaving a net gain of $33.13*.

Frequently Asked Questions

Q: How does funding rate affect my profit and loss on CoinEx?

A: Funding rates are periodic payments made between long and short traders in perpetual contracts. If the funding rate is positive, longs pay shorts; if negative, shorts pay longs. These fees accumulate over time and reduce your net profit or increase your loss depending on your position.

Q: Can I see profit and loss in different currencies on CoinEx?

A: Yes, CoinEx allows users to view profit and loss in various settlement currencies, including USDT, BTC, and ETH, depending on the contract pair being traded. You can switch between these currencies within your account settings or on the trade details page.

Q: Is unrealized PnL affected by mark price on CoinEx?

A: Yes, unrealized profit and loss on CoinEx is calculated using the mark price, not the last traded price. This ensures fairness and prevents manipulation. Mark price is derived from the average price across major spot exchanges and may differ slightly from the current market price.

Q: What happens to my PnL if my position gets liquidated on CoinEx?

A: If your position reaches the liquidation price, it will be forcibly closed by the system. At this point, your realized PnL will reflect the loss up to the liquidation point, and you may lose part or all of your initial margin depending on the severity of the liquidation.
