Pair A/B
A is called base currency/token; B is called quote currency/token. Currently quote currency for contracts is USD.
Contracts are traded by base currency/token. Equity, Unrealized P/L, Realized P/L, etc. are quoted by base currency/token.
Open Price
[Base contract]
For the positions opened on day
Open price = (Contract volume of filled price 1 + Contract volume of filled price 2 +…...) / (Contract volume of filled price 1/ Filled price 1 + Contract volume of filled price 2/ Filled price 2 + ……)
For the positions opened on previous day
Open price = Settled price on yesterday
For the positions opened on day and previous day
Open price = (Contract volume of yesterday’s position + Contract volume of filled price 1 + Contract volume of filled price 2 +…...) / (Contract volume of yesterday’s position / Settled price on yesterday + Contract volume of filled price 1/ Filled price 1 + Contract volume of filled price 2/ Filled price 2 + ……)
[Quote Contract]
For the positions opened on day
Open price = (Filled price 1 * Contract volume of filled price 1 +(Filled price 2 * Contract volume of filled price 2 +…...) / (Contract volume of filled price 1 + Contract volume of filled price 2 + ……)
For the positions opened on previous day
Open price = Settled price on yesterday
For the positions opened on day and previous day
Open price = (Settled price on yesterday * Contract volume of yesterday’s position + Filled price 1 * Contract volume of filled price 1 + Filled price 2 * Contract volume of filled price 2 +…...) / (Contract volume of yesterday’s position + Contract volume of filled price 1 + Contract volume of filled price 2 + ……)
Frozen
The assets occupied by open orders.
Available
Assets can be used to open contracts in contract account
Available = Equity – Margin – Frozen – Unrealized P/L – realized P/L
Max Open
Maximum contracts that can be opened using available.
Max Open = Available * Leverage Ratio / ((Contract Multiplier / Order Price) * (1+Taker Fee))
Tips: It calculates according to order price entered by customer; if not entered, order price is replaced by last price.
Open Value
During trading time, Open Value = Open Interest * Contract Multiplier / Last Price.
During settlement, Open Value = Open Interest * Contract Multiplier / Last Settlement Price
Total
Filled contract value quoted by base currency/token. Total = Vol * Contract Multiplier / Fill Price
Equity
Equity = Account Balance + Unrealized P/L
Account Equity = Account Equity Previous Day + Net Deposit + Realized P&L + Unrealized P&L –Fees on day Initial Account Equity = Initial Deposit
Account Balance
Total assets in contract account. Realized P/L will be added to account balance after closing.
Unrealized P/L will be added to account balance after settlement/delivery.
Realized P/L
P/L of closed positions before settlement/delivery. Realized P/L is total realized P/L of all contracts with different expirations.
For the based contract, the computation of realized P/L is:
Long positions：Realized P/L = (1/ Open price - 1 / Close price) * Number of Contracts Closed * Contract Multiplier
Short positions：Realized P/L = (1 / Close price - 1/ Open price) * Number of Contracts Closed * Contract Multiplier
For example：
a user holds 100 conts of BTC seasonal long contract (cont value is 100 USD), open price is 5000 USD/BTC. if the close price is 4000 USD/BTC, the realized profit and loss of these long position is (1/5000 - 1/4000) *100*100 = -0.5BTC
Realized P&L will be added to the account balance directly when positions are closed.
For quoted contract, the computation of realized P/L is:
Long positions：Realized P/L = (Close price - Open price) * Number of Contracts Closed*Contract multiplier
Short positions：Realized P/L = (Open price - Close price) * Number of Contracts Closed* Contract multiplier
For example：
a user holds 100 conts of BNB seasonal long contract (cont value is 1BNB), open price is 30 BNB/USD. if the close price is 40 BNB/USD, the realized profit and loss of these long position is (40 -30) *100 = 1000.
Realized P&L will be added to the account balance directly when positions are closed.
Unrealized P/L
the profit and loss that happened when user has positions. the price of unrealized profit and loss moving with the latest price.
For the based contract, the computation of unrealized P/L is:
Long positions：Unrealized P/L = (1/Open Price - 1/Last Price)*Long Positions*Contract Multiplier
Short positions: Unrealized P/L = (1/Last Price - 1/Open Price)*Short Positions*Contract Multiplier
For example:
A user holds 100 conts of seasonal long contract (cont value is 100 USD), open price is 5000 USD/BTC. if the close price is 8000 USD/BTC, the unrealized profit and loss of these long position is (1/5000 - 1/8000) *100*100 = 0.75BTC
For the quoted contract, the computation of unrealized P/L is:
Long positions：Unrealized P/L = (Last Price - Open Price) *Long Positions* Contract multiplier
Short positions: Unrealized P/L = (Open Price - Last Price) *Short Positions* Contract multiplier
For example:
A user holds 100 conts of BNB seasonal long contract, open price is 30 BNB/USD. The close price is 40 BNB/USD, the realized profit and loss of these long position is (40 - 30) *100 = 1000.
