Profit & Loss Calculation
USDT based Margin
Floating PNL = [Contract Size * (Current Price - Entry Price)] / (Current Price*Exchange Rate)
Example 1:
"Choose USDT as the settlement currency to trade BTC/USDT contracts
At a price of 10,000 USDT for BTC/USDT, User A spends 10,000 USDT to open long and closes it at a price of 15000 USDT."
PNL(Profit and Loss) = [10000 * (15000-10000)] /(10000 * 1) = 5000 USDT
Crypto based Margin
Floating PNL = [Contract Size * (Current Price - Entry Price)/ (Current Price* Entry Price)] *Exchange Rate
Example 2:
"Choose BTC as the settlement currency to trade ETH/USDT contracts
At a price of 400 USDT for ETH/USDT, User A spends 10,000 USDT to open long and closes it at a price of 500 USDT. Suppose the spot rate of ETH/BTC is 0.03 at this time."
PNL(Profit and Loss) = [10000 * (500-400)/(400 * 500)] *0.03= 0.15 BTC
Liquidation Price Calculation
Isolated Margin Mode
USDT based Margin
Long: [1-(Margin+Additional Margin)*1/(Contract Size*Contract Multiplier)+Maintenance Margin Rate)*Opening Price
Short: [1+(Margin+Additional Margin)*1/(Contract Size*Contract Multiplier)-Maintenance Margin Rate)*Opening Price
Crypto based Margin
Long: 1.0 / [(1.0 - Maintenance Margin Rate) / Opening Price + (Margin + Additional Margin) / (Contract Size * Exchange Rate)]
Short: 1.0 / [(1.0 + Maintenance Margin Rate) / Opening Price - (Margin + Additional Margin) / (Contract Size * Exchange Rate)]
Cross Margin Mode
USDT based Margin
Liquidation Price = (longQty - shortQty - cash * cxRate / refData.getValuePerUnit()) / (longQty / longPrice - shortQty / shortPrice - Math.abs(longQty / longPrice - shortQty / shortPrice) * maintenanceMarginRate)
Crypto based Margin
Liquidation price = (longQty - shortQty) / (longQty / longPrice - shortQty / shortPrice + cash / (refData.getValuePerUnit() * cxRate) - Math.abs(longQty / longPrice - shortQty / shortPrice) * maintenanceMarginRate)
