1. Account structure
Currently, the system supports two types of margin modes: isolated margin mode and cross margin mode.
Under the isolated margin mode, the margin for each position is separate and not combined with other positions for calculation.
Under the cross margin mode, the margin is shared among all positions.
Definitions：
Transfer: It is used to transfer funds between other accounts of the user (cryptocurrency,contract accounts).
Position margin: The margin occupied by the positions, that is, the opening margin.
Order margin: The margin occupied by orders not concluded, which includes service charges and is frozen.
Realized profits and losses: The actual earnings obtained from closing positions, which may be used as margins or withdrawn.
Unrealized profits and losses: The profits and losses of positions that are not closed in all the current positions, also known as floating profits and losses.
Direction: It can be divided into two types: buy (open long) and sell (open short).
Leverage: It shows the opening leverage.
Positions: The number of open positions.
Position value = Latest price * Position size* Contract multiplier
Position margin: The margin required for holding a position, which is frozen and will follow the market changes.
Under isolated margin mode, the margin for a position can be added or removed at will.
Under cross margin mode, the margin cannot be added or removed.
Position margin: Position margin: The margin occupied by the positions, which is frozen. The position margin varies with the change of market price at any time. The position margin may also be increased or decreased at any time.
Average opening price: The average opening price of the positions.
Estimated liquidation price: The system will execute the liquidation process immediately when the latest price reaches this estimated liquidation price.
Margin rate: Position margin / Position value.
Price index: BTC Price Index. Average price based on the spot trading of mainstream exchanges such as Binance, OKEX, Huobi, etc.
Unrealized profits and losses: The profits and losses of positions that are not closed in the current positions, also known as floating profits and losses. Note: These unrealized profits and losses refer to only those of the current positions (sold (opened long)).
The right zone is used for quick closing. The closing methods include limit, market price, opponent, queue and over. Please refer to the Order management section for detailed closing methods.
2. Calculation of profits and losses
Users may solely decide to buy or sell contracts according to market conditions and personal willingness.
Realized profits and losses refer to the profits and losses incurred by the user when actually closing the positions.
Realized PNL of Futures Contracts:
Long position: Realized PNL of the contract = (Exit price - Entry price) * Position size * Contract multiplier
For example, if a user buys 100 BTC contracts at an average entry price of 800 USDT/BTC, and then sells 100 contracts at an average exit price of 1600 USDT/BTC, with the contract multiplier being 0.0001, the realized PNL would be (1600 - 800) * 100 * 0.0001 = 8 USDT.
Short position: Realized PNL of the contract = (Entry price - Exit price ) * Position size * Contract multiplier
For example, if a user sells 100 BTC contracts at an average entry price of 800 USDT/BTC, and then buys back 100 contracts at an average exit price of 1600 USDT/BTC, with the contract multiplier being 0.0001, the realized PNL would be (800 - 1600) * 100 * 0.0001 = -8 USDT.
Unrealized PNL of Futures Contracts:
Long postion: Unrealized PNL of the contract = (Latest price - Entry price) * Position size * Contract multiplier
For example, if a user buys 100 BTC contracts at an average entry price of 500 USDT/BTC, and the latest traded price is 600 USDT/BTC, with the contract multiplier being 0.0001, the unrealized PNL would be (600 - 500 ) * 100 * 0.0001 = 1 USDT.
Short postion: Unrealized PNL of the contract = (Entry price - Latest price) * Position size * Contract multiplier
For example, if a user sells 100 BTC contracts at an average entry price of 500 USDT/BTC, and the latest traded price is 600 USDT/BTC, with the contract multiplier being 0.0001, the unrealized PNL would be (500 - 600) * 100 * 0.0001 = -1 USDT.
