Account Structure & Profit and Loss Calculation

Each account on BKEX will have a separate "contract asset account". Since BKEX currently only supports forward perpetual contract tradings based on USDT trading and settlement, traders need to deposit USDT in this account or transfer USDT from C2C ​​accounts Funds can only be used for contract tradings. The following contract asset information can be seen on the "Assets-Perpetual Contract Account" page in the platform APP.

Contract Account Structure Description

Account Equity: Account Balance + Unrealized Profit and Loss.

Available: Account Balance - Freeze Margin - Entrusted Margin + Unrealized Loss.

Realized profit and loss: The profit and loss generated by the user's closed position.

Unrealized profit and loss: the profit and loss generated by the user's current position, also known as floating profit and loss.

Entrustment margin: the funds that contract traders need to freeze when issuing orders.

Maintenance Margin: The minimum amount of funds that a contract investor needs to keep in the account in order to hold a certain contract position.

Profit and loss calculation

In BKEX's forward perpetual contract, we define the current mark price as P0 and the trader's average trading price as P1, then the trader's profit and loss calculation method:

a) If buying/going long: Pnl = (P0 - P1) * Contract Quantity *1 - Trading Fee.

b) If it is sell/short: profit and loss Pnl = (P0 - P1) * contract quantity *-1 - trading fee.

Here's an example of how to calculate profit and loss:

a) Suppose a trader buys 10 BTC/USDT futures at an average price of 7,000USDT, and the current contract mark price is 8,000USDT, excluding the handling fee factor:

The trader's unrealized profit = (8,000 - 7,000) * 10* 1 = 10000 USDT

b) Suppose a trader sells 10 BTC/USDT forward futures at an average price of 7,000USDT, and then closes the position when the mark price is 6,000USDT, excluding the handling fee factor:

The trader's realized profit = (6,000 - 7,000) * 10 * -1 = 10000 USDT

*BKEX perpetual contract does not support profit and loss offset.

The mark price is used to calculate the unrealized profit and loss instead of the latest market price. Traders can view real-time P/L and unrealized P/L in the position area at any time.
