Perpetual Contract Formula

Contract Transferable To currency Amount

• Cross Margin = Account Balance + Unrealized Profit and Loss - Sum of All Position Margins - Sum of All Order Margins
• Isolated Margin = Account Balance - Current Position Margin - Current Order Margin

Contract available margin

• Cross Margin = Account Equity - All Position Margin - All Order Margin.
• Isolated Margin = Account Equity - Current Position Margin - Current Order Margin.

Order Placement Conditions

• Cross Margin = Account Balance + Unrealized Profit and Loss (sum of long and short positions) - Total Position Margin - Total Order Margin > 0.
• Isolated Margin = Account Balance - Current Position Margin - Current Order Margin > 0.

Position Opening Quantity = Available Margin × Leverage ÷  ( Latest Mark Price × Contract Size )

• Actual Position Opening Quantity = [ Available Margin - ( Position Opening Quantity × Contract Size × Latest Mark Price × Trading Fee )] × Leverage ÷ ( Latest Mark Price × Contract Size )
• Opening Fee = Contract Size × Opening Order Quantity × Opening Price × Trading Fee
• Closing Fee = Contract Size × Closing Order Quantity × Closing Price × Trading Fee
• If it is in Isolated Margin mode, unrealized profit and loss cannot be used for adding positions. If it is in Cross Margin mode, unrealized profit and loss can be used for adding positions.

Average Opening Price

• Average Opening Price = (Original Position Quantity × Original Opening Average Price + New Opening Quantity × New Opening Execution Price) ÷ (Original Position Quantity + New Opening Quantity)

Order Margin (Same for both Cross and Isolated Margin)

• Order Margin = Contract Size × Contract Quantity × Average Opening Price ÷ Leverage.

Position Margin:

• Cross Margin = Contract Size × Contract Quantity × Latest Mark Price ÷ Leverage.
• Isolated Margin = Contract Size × Contract Quantity × Opening Average Price ÷ Leverage.
• Position Value = Contract Size × Contract Quantity × Latest Mark Price.

Margin Rate (Real-time Calculation using Mark Price):

• Cross Margin = (Contract Account Balance + Unrealized PnL) ÷ [Sum of (Mark Price ÷ Contract Quantity ÷ Contract Size) + Sum of (Order Price ÷ Contract Quantity ÷ Contract Size) ÷ (1 + Trading Fee ÷ Leverage)].
• Isolated Margin = (Position Margin + Unrealized PnL of Current Position) ÷ (Contract Size × Contract Quantity × Latest Mark Price).
• Forced Liquidation = Margin Rate  ≤  User's Current Required Maintenance Margin Rate + Liquidation Fee .

Note: For Cross Margin Contract Quantity is the sum of quantities when both long and short positions are open.

Unrealized Profit and Loss (Calculated using Mark Price in Real Time):

• Long Position = Contract Size × Contract Quantity × (Latest Mark Price - Opening Average Price).
• Short Position = Contract Size × Contract Quantity × (Opening Average Price - Latest Mark Price).

Realized Profit and Loss:

• Long Position = (Closing Price - Opening Average Price) × Contract Size × Closing Quantity.
• Short Position = (Opening Average Price - Closing Price) × Contract Size × Closing Quantity.
• Profit = Unrealized PnL (Calculated using Mark Price in Real Time).

Position Profit Rate:

• Profit Rate = Profit ÷ Position Margin.

Account Equity:

• Cross Margin = Account Balance + Sum of Unrealized Profit and Loss of all Cross Margin Positions.
• Isolated Margin = Account Balance.

Estimated Liquidation Price:

• Cross Margin Long Position = [(Contract Account Balance + Sum of Unrealized PnL of all Positions - Frozen Margin) ÷ (Contract Size × Long Position Contract Quantity) - Opening Price] ÷ (Maintenance Margin Rate + Liquidation Fee Rate - 1).
• Cross Margin Short Position = [(Contract Account Balance + Sum of Unrealized PnL of all Positions - Frozen Margin) ÷ (Contract Size × Long Position Contract Quantity) + Opening Price] ÷ (Maintenance Margin Rate + Liquidation Fee Rate + 1).
• Isolated Margin Long Position = [Fixed Margin of Long Position ÷ (Contract Size × Long Position Contract Quantity) - Opening Price] ÷ (Maintenance Margin Rate + Liquidation Fee Rate - 1).
• Isolated Margin Short Position = [Fixed Margin of Short Position ÷ (Contract Size × Short Position Contract Quantity) + Opening Price] ÷ (Maintenance Margin Rate + Liquidation Fee Rate + 1).
