Position & PnL FAQs

1. Why does unrealized PnL change?

Unrealized PnL refers to the floating profit or loss of your current position, calculated in real time using the latest market price. It changes continuously as market prices fluctuate.

For example:

• Unrealized PnL for long positions usually increases when prices rise
• Unrealized PnL for short positions usually increases when prices fall

Unrealized PnL only reflects the floating profit or loss of your current position and is generally not settled into your account balance until the position is closed.

2. What is the difference between realized PnL and unrealized PnL?

Unrealized PnL refers to the floating profit or loss of an open position and changes with market prices.

Realized PnL refers to the actual profit or loss that is finalized after a position is closed and is usually reflected in your account balance.

3. Why is my ROI different from what I expected?

ROI is affected not only by price movements, but also by leverage, margin size, trading fees, and funding fees. As a result, actual ROI may differ from what you expected.

In most cases, ROI is calculated based on the margin invested rather than the total position value. Therefore, under high leverage, even small market price movements may lead to significant ROI fluctuations.

4. Why does the liquidation price change?

The liquidation price is dynamically calculated based on your current position and is therefore not fixed.

The system will recalculate the liquidation price when:

• Position size changes
• Leverage adjustments
• Margin increases or decreases
• PnL changes
• Funding fee settlements

5. Why did my position size change?

Changes in position size are usually caused by the following situations:

• Manually adding to or reducing positions
• Partial order fills
• Take-profit or stop-loss orders being triggered
• Partial liquidation
• Contract settlement at expiry (applicable to delivery futures)

If the position is fully closed, the position will no longer be displayed in your current positions.

You can check your position history, trade history, or fund records for more details.

6. Why hasn't my profit shown up in my account balance yet?

Even if your position is showing a profit, unrealized PnL is usually not immediately added to your available account balance.

Only after the position is closed will the profit become realized PnL and be settled into your account balance.

7. Why doesn’t my trade history match my position PnL?

Position PnL usually reflects only the floating profit or loss generated by the position itself.

However, actual trade records may also include factors such as opening fees, closing fees, funding fees, and price differences from partial fills.

As a result, the final actual PnL may differ from the PnL displayed on the position page.

You can review your fund records, trade history, and funding fee history for more details.

8. What are funding fees?

Funding fees are periodic payments exchanged between long and short position holders in the perpetual futures market to help keep contract prices closer to the spot index price.

Funding fees are not additional platform trading fees.

Depending on whether the funding rate is positive or negative:

• When the funding rate is positive, long position holders pay funding fees to short position holders
• When the funding rate is negative, short position holders pay funding fees to long position holders

Funding fees are usually settled periodically. Please refer to the trading page for the specific settlement schedule and rules.

9. Why does my account balance change while I have open positions?

Account balance changes are usually related to the following factors:

• Unrealized PnL changes
• Funding fee settlements
• Trading fee deductions
• Automatic transfers or margin adjustments

Changes in account balance may become more noticeable during periods of high market volatility or when holding larger positions.

Please review your fund records for more details.

10. What is the difference between Mark Price and Last Price?

Mark Price is the reference price used by the platform to calculate unrealized PnL and liquidation prices. It is typically calculated based on factors such as spot prices, index prices, and funding rates.

Using Mark Price helps reduce the impact of abnormal market volatility on liquidations.

Last Price refers to the price of the most recent trade in the market.

Therefore:

• Unrealized PnL is usually calculated based on Mark Price
• Liquidation prices are usually triggered based on Mark Price
• Last Price may temporarily differ from Mark Price

11. Why can my account still show losses after liquidation?

The liquidation price is only an estimated reference price provided by the system and does not guarantee execution at that exact price.

During periods of extreme volatility or insufficient liquidity, the actual execution price may differ from the estimated liquidation price, which may result in additional losses after liquidation.
