Glossary and Formula

Funds are segregated into "sub accounts" under fixed margin mode. Each sub account consists of balance, RPL, amount on hold and UPL.

Funds can be freely transferred between "Perpetual Swap Account" and "Spot Account". But the funds in the sub accounts can only be transferred out after all the contract positions are closed. RPL can only be transferred out after settlement.

Balance (account): margin for all open positions, can be transferred to sub accounts for adding margin.

Balance (sub account): margin for the open positions. Together with RPL, they act as the Collateral OCC

Avail. Margin: the margin available for opening new positions

Realized PL: Your gains and losses, from the last settlement till now, that have been realized by closing your position. It can be used as margin for the open positions and open orders.

Order Margin: The margin required for open orders of the contract. After the order is filled, the value will be added to the Collateral OCC, which consists of equity and RPL.

Used margin: The margin required for the positions of the perpetual swap. The margin will remain the same after opening or closing the positions, but it can be added manually by the user.

Number	Term	Description
1	Equity	The total sum of assets in your account, which is Balance + RPL + UPL
2	Balance	The collateral deposited to the account (can be transferred from Wallet / Spot / Futures / ETT accounts). After settlement, your RPL and UPL will be credited here too.
3	Realized P/L	The profit and loss of the closed positions since the last settlement (08:00 UTC daily).
4	Unrealized P/L	The profit and loss of the open positions since the last settlement (08:00 UTC daily).
5	Avail. Margin	The margin available for opening positions, which is = Equity - required Maintenance Margin - Margin on Hold
6	Used Margin	The margin used for open positions = Maintenance Margin + Margin on Hold
7	Order Margin	Margin withheld for open orders

Number	Term	Description
1	Open Position (token / contract)	The Number of contracts open. The unit can be switched to USDT. Open Position = Face value x Number of contracts x Last Filled Price
2	Avail. Cont	The Number of contracts closable, which is Number of contracts open - Number of contracts frozen
3	Margin	Face Value x Number of contracts x Latest Mark Price / Leverage
4	PL	Profit of the current Open Position, including the RPL and UPL settled and credited to Balance.
5	PL Ratio	Profit/initial margin
6	Avg. Price	The average cost of opening the position, which will not vary with settlement and accurately reflects the cost of opening this position
7	Setl. Price	The price used to calculate the UPL. The price will be adjusted every day during settlement. However, such adjustment does not affect users’ actual profit.
8	Liquidation Price	The price that, when used as Latest Mark Price in the calculation of the Margin Ratio, makes Margin Ratio equal to the required Maintenance Margin Ratio + Liquidation Fee Rate. When the Mark Price reaches this price, Full or Partial Liquidation occurs.
9	Settled Earnings	The profit that credited to your balance from the settlement procedure.
10	Unrealized P&L	The profits or losses of your open positions. All UPL will be settled and credited to user balance at settlement every day. Then the UPL will be reset. Long position：（latest mark price-settlement reference price）x number of contracts x face value Short Position：（settlement reference price - latest mark price price）x number of contracts x face value
11	Margin Ratio	A risk indicator for the account, which is (Fixed Margin + UPL) / Position Value = (Fixed Margin + UPL) / (Face Value x Number of contracts x Latest Mark Price)
12	Maintenance Margin Ratio	The lowest possible Margin Ratio for maintaining the current positions. Full or Partial Liquidation will occur if Margin Ratio is lower than Maintenance Margin Ratio + Liquidation Fee Rate.

Profit and loss

Before settlement, users can buy and sell the contract at their own discretion.

RPL is the profit and loss generated from closing positions.

RPL of a contract:

Open long: RPL = (Face Value x Average Closing Price - Face Value x Settlement Reference Price) x Number of contracts closed.

E.g. Jackson opened 200 long BTC contracts at the Settlement Reference Price of 5000 USDT/BTC, then closed 100 contracts at 1,0000 USDT/BTC, the RPL is then = (0.0001 BTC x 10000 USDT/BTC - 0.0001 BTC x 5000 USDT/BTC) x 100 = 50 USDT.

Open short: RPL = (Face Value x Settlement Reference Price - Face Value x Average Closing Price) x Number of contracts closed.

E.g. Jackson opened 1000 short BTC contracts at the standard settlement price 5000USDT/BTC, then closed 800 contracts at 1,0000 USD/BTC, the RPL is then = (0.0001 BTC x 5000 USDT/BTC - 0.0001 BTC x 1,0000 USDT/BTC) x 800 = - 400 USDT.

UPL of a contract

Open long: UPL = (Face Value x Latest Mark Price - Face Value x Settlement Reference Price) x Number of contracts held

 E.g. Jackson opened 600 long BTC contracts at the Settlement Reference Price of 500 USDT/BTC, and the latest mark price is 600 USDT/BTC , the UPL is then = (0.0001 BTC x 600 USDT/BTC - 0.0001 BTC x 500 USDT/BTC) x 600 = 6 USDT.

Open long: UPL = (Face Value x Settlement Reference Price - Face Value x Latest Mark Price) x Number of contracts held

E.g. Jackson opened 1000 short BTC contracts at the settlement reference price of 1000USDT/BTC, and the latest mark price is 500 USD/BTC, the UPL is then = (0.0001 BTC x 1000 USDT/BTC - 0.0001 BTC x 500 USDT/BTC) x 1000 = 50 USDT.
