Position Size = (Initial Investment × Leverage) / Entry Price
Long Position:
P&L = Position Size × (Exit Price - Entry Price)
Short Position:
P&L = Position Size × (Entry Price - Exit Price)
Funding Intervals = floor(Hours Held / 8)
Funding Cost = Position Value × (Funding Rate / 100) × Intervals
Entry Fee = Position Value × (Trading Fee / 100)
Exit Fee = Exit Value × (Trading Fee / 100)
Total Fees = Entry Fee + Exit Fee
Net P&L = Raw P&L - Total Costs
ROI = (Net P&L / Initial Investment) × 100
Long Position:
Liquidation = Entry Price × (1 - (1/Leverage) + Maintenance Margin Rate)
Short Position:
Liquidation = Entry Price × (1 + (1/Leverage) - Maintenance Margin Rate)
Maintenance Margin Rate: 0.4% (standard for most Binance pairs)
