*Total assets
Total asset value = available balance + entrusted order margin + position margin + unrealized profit and loss

*Account available balance
Available balance = total contract account value - margin required for current positions - margin occupied by entrusted pending orders - unrealized profit and loss

*Opening margin
Margin = opening price × number of positions opened × face value ÷ leverage multiple

*Profit and loss calculation
1. Calculation of unrealized profit and loss
Long position profit = number of positions × face value × (marked price - average opening price)
Short position profit = number of positions × face value × (average opening price - marked price)
Yield = Unrealized Profit and Loss ÷ Position Margin

2. Calculation of profit and loss from closing position
Profit and loss from closing long positions = number of positions closed × face value × (average closing price – average opening price)
Profit and loss of short position closing = number of positions closed × face value × (average opening price – average closing price)

3. Position closing settlement formula
Long position closing settlement = (Closing volume ÷ Shareholding volume) × Position margin + Closing volume × (Closing price - Average opening price) - Closing price × Closing volume × Handling fee
Short position closing settlement = (Closing volume ÷ Position volume) × Position margin + Closing volume × (Opening price - Average closing price) - Closing price × Closing volume × Handling fee

*Margin rate-calculation formula
Margin rate = (margin balance + unrealized profit and loss) ÷ (number of positions × face value × marked price × (maintenance margin rate + handling fee) )

*Estimated forced parity price - calculation formula
Estimated liquidation price of long positions = (margin balance - position × average opening price) ÷ (holding × (maintenance margin rate + handling fee - 1))
Estimated liquidation price of short position = (margin balance + position × average opening price) ÷ (holding × (maintenance margin rate + handling fee + 1))

*Transaction Fees
1. Transaction fee collection
When opening a position, the handling fee will be deducted from the user's available balance. When the available balance is insufficient, the handling fee will be deducted directly from the position margin;
When closing a position, the transaction fee will be deducted from the closing settlement balance;
2. Transaction fee calculation
Opening fee = number of positions opened × face value × opening price × handling rate
Liquidation fee = liquidation quantity × face value × liquidation price × handling fee
