Inverse Contracts Equity
Equity refers to the actual net assets in the futures account.
Equity = Transferred-in Amount - Transferred-out Amount + Realized PNL + Unrealized PNL
Inverse Contracts PNL
1. Cumulative PNL
The Cumulative PNL refers to the PNL since opening the position, estimated at the Mark Price or the Latest Price.
Cumulative PNL = Realized PNL + Unrealized PNL
2. Unrealized PNL
Unrealized PNL is based on the difference between the Settlement Price and the Mark Price (or the Latest Price ), and the estimated profit is based on the number of your open positions.
The Unrealized PNL will be shown in your position details after you have successfully opened a position, which is an estimated value of your PNL.
Unrealized PNL (Long) = Contract Amount * Contract Value * (1 / Settlement Price - 1 / Mark Price)
Unrealized PNL (Short) = Contract Amount * Contract Value * (1 / Mark Price - 1 / Settlement Price)
It is the realized PNL that WILL affect your final profit and loss, NOT the unrealized PNL.
3. Realized PNL
The realized PNL includes the funding fees, the trading fees, and the settlement PNL of decreased or closed positions.
(1) Funding Fee
The Funding Fee is a mechanism to ensure that the Futures market price is close to the Spot market price. For details, please refer to An Introduction to Funding Fee.
(2) Trading Fee
The trading fee is charged when buying or selling contracts and realized PNL is made when the payment is completed.
(3) Settlement PNL
Settlement PNL (Long) = Position Amount * Contract Value * (1 / Last Settlement Price - 1 / Current Settlement Price)
Settlement PNL (Short) = Position Amount * Contract Value * (1 / Current Settlement Price - 1 / Last Settlement Price)
(4) Decreased Position / Closed Position Settlement
When all your positions are decreased or closed, the realized PNL of these positions will be settled according to the closing price and settlement price.
Realized PNL (Long) = Contract Amount * Contract Value * (1 / Settlement Price - 1 / Closing Price)
Realized PNL (Short) = Contract Amount * Contract Value * (1 / Closing Price - 1 / Settlement Price)
▪ Under the Isolated Margin mode, your settlement PNL will still be credited to the current margin during settlement. If there is profit, you can transfer it to your balance manually. The realized PNL when closing the position will be credited to your balance directly.
▪ Under the Cross Margin mode, your settlement PNL will be credited to the current margin during settlement. If there is an excess margin(a.k.a profit), it will be transferred to your balance automatically. The realized PNL when closing the position will be credited to your balance directly.
4. Profit & Loss Rate (PNL%)
The current PNL% of your open contracts is estimated at the mark price or the latest price.
PNL% = Total PNL / Initial Margin
About Settlement Prize
The Settlement Price is the price at which unrealized PNL and realized PNL are calculated. The price of opening positions, adding positions, and settlement will be adjusted accordingly.
Please refer to What's Settlement Price for how to calculate settlement price when Pyramiding Auto-Settlement is enabled.
