Entry Price
Options with the same expiration date, strike price and type are considered one position. If you increase or reduce the position, the entry price will be affected, and the calculation is as follows:
Entry Price = (Entry Price Before Trading × Position Amount Before Trading + Entry Price Currently × Position Amount Changed) / (Position Amount Before Trading + Position Amount Changed)
Position Value
The position value is calculated based on the mark price and positions amount, and the calculation is as follows:
Position Value = Mark Price x Contract Multiplier x ABS(Position Amount)
Unrealized PNL
The unrealized PNL is the profit and loss of the current position at the current mark price, and will fluctuate with the change of the mark price. The specific calculation is as follows:
Unrealized PNL = (Mark Price - Entry Price) × Contract Multiplier × Position Amount
Realized PNL
The realized PNL is the trading fees and the profit and loss of manual position reduction. The calculation is as follows:
Realized PNL = Trading Fee + PNL of Reducing Position Manually
For more detailed calculation of trading fees, please refer to Options Fees
Expiration PNL
When the option expires, the expiration PNL needs to be calculated based on the relationship between the strike price and the market price of the underlying assets at the time of expiration. The possible scenarios are as follows:
-
At-the-money/Out-of-the-money Option → Not exercisable, the option becomes invalid, so the option buyer will not exercise the option
PNL = 0 -
In-the-money option → Exercise with PNL
PNL = (Settlement Price - Strike Price) × Contract Multiplier × Position Amount - Strike Price
Please note: The expiration PNL only considers the profit and loss after the position is entried and does not include the premium. For descriptions of In-the-money, At-the-money and Out-of-the-money options, please refer to Introductions of Gate’s Options
