Coin-Margined Futures Position Info

Quantity

The average entry price of a position changes with each addition or reduction by the user.

Example: You currently hold a BTCUSD contract, going long with 1000 contracts. The entry price is 50,000 USDT. An hour later, you decide to open an additional 2000 contracts at a price of 60,000 USD. Then:

Average entry price = Total contract quantity/Total value of BTC contract

• Total number of contracts = 1000 + 2000 = 3000
• Total value of BTC contract = (1,000/50,000) + (2,000/60,000) = 0.053333334 BTC

Average entry price = (3000/0.053333334) = 56250.00 USD

Unrealized PNL for long positions = Quantity × (1/Average entry price - 1/Mark price)

Unrealized PNL for short positions = Quantity × (1/Mark price - 1/Average entry price)

• Long position example

You currently hold a BTCUSD contract, going long with 1000 contracts. The entry price is 50,000 USDT. When the latest mark price is 55,000 USD, unrealized PNL will show as 0.001818 BTC.

Unrealized PNL = Contract quantity x [(1/Average entry price) - (1/Mark price)] = 1000 x [(1/50000) - (1/55000)] = 0.001818 BTC

• Short position example

You currently hold a BTCUSD contract, going short with 1000 contracts. The entry price is 50,000 USDT. When the latest mark price is 45,000 USD, unrealized PNL will show as 0.02223 BTC.

Unrealized PNL = Contract quantity x [(1/Mark price) - (1/Average entry price)] = 1000 x [(1/45000) - (1/50000)] = 0.002222 BTC

Note: The calculation of unrealized PNL does not include any trading fees or funding fees paid or received by the user during the position opening/closing/holding process.

Realized PNL = ∑PNL from position reduction - Trading fees - Total funding fees after opening the position

Realized PNL includes all trading fees, funding fees, and profits/losses realized from partial position closings. The calculation for realized PNL remains consistent with the formula used for unrealized PNL.

Example: You currently hold a BTCUSD contract, going short with 1000 contracts. The entry price is 50,000 USDT. You close 500 contracts at a price of 45,000, leaving 500 contracts still open.

• Partial closing P&L = 500 x [(1/45000) - (1/50000)] = 0.001117778 BTC

• Position opening fee = (1,000/50000) x 0.06% = 0.000012 BTC

• Position closing fee = (500/45000) x 0.06% = 0.000006667 BTC

• Total funding fee paid = 0.00005 BTC

Realized P&L of position = 0.001117778 - 0.000012 - 0.000006667 - 0.00005 = 0.001049111 BTC
