Options P&L Calculation

Before an options contract expires, users can voluntarily decide to buy or sell options contracts based on market conditions and personal preferences. Once a user buys or sells an options contract, they acquire the right or obligation to fulfill the options contract at expiration, which is specifically reflected in the "position" of the options contract.

Realized P&L: The profit or loss generated from closed positions from the last settlement time to the current time. Realized P&L is credited to the Account balance, can be used as margin but cannot be withdrawn. After the current settlement, the realized P&L generated during the period can be withdrawn to the Trading Account.

Closing long positions: (Closing execution price - Settlement reference price) * Contract multiplier * Number of contracts;

Example: A user buys 2 BTC contracts at 0.02 BTC, with a contract multiplier of 0.01 and a settlement reference price of 0.03 BTC, then sells 1 contract to close the long position at 0.04 BTC. Realized P&L = (0.04 – 0.03) * 0.1 * 1 = 0.001 BTC.

Closing short positions: (Settlement reference price - Closing execution price) * Contract multiplier * Number of contracts;

Example: A user opens 10 short contracts at a settlement reference price of 0.03 BTC, then buys 8 contracts to close the short position at 0.01 BTC. Realized P&L = (0.03 – 0.01) * 0.1 * 8 = 0.016 BTC.

Unrealized P&L: The profit or loss generated from open positions from the last settlement time to the current time, which is also reflected in real-time options market value.

Long positions: Unrealized P&L = Mark price * Contract multiplier * Number of contracts held - Opening average price (or settlement price) * Contract multiplier * Number of contracts held;

Example: A user buys 2 BTC contracts at a settlement reference price of 0.03 BTC, with a mark price of 0.04 BTC. Unrealized P&L = 0.04 * 0.1 * 2 - 0.03 * 0.1 * 2 = 0.002 BTC.

Short positions: Unrealized P&L = Opening average price (or settlement price) * Contract multiplier * Number of contracts held - Mark price * Contract multiplier * Number of contracts held;

Example: A user sells 5 BTC contracts at a settlement reference price of 0.03 BTC, with a mark price of 0.02 BTC. Unrealized P&L = 0.03 * 0.1 * 5 - 0.02 * 0.1 * 5 = 0.005 BTC.
