Profit and Loss (PNL) and Return on Investment (ROI)
You can view the profit and Loss of an option position from the time it was opened to the present through the Profit and Loss (ROI) on the Positions page.
Position profit and loss (PNL) is the sum of the realized PNL and the unrealized PNL of an option position since opening, and th return on investment (ROI) is the rate of return of an option position since opening.
Profit and Loss PNL = (mark price - average price) * position size (coin)
ROI (option buyer / long position) = (mark price - average price) / average price * 100%
ROI (option seller / short position) = (average price - mark price) / average price * 100%
Note: average price refers to the price of opening the position
Example.
Amy has a long position of 0.5 BTC in BTC-USD-24JUN22-30000-P with a real-time mark price of 100 USD and an average opening price of 120 USD, then the PNL and ROI of Amy’s position is as follows
PNL = (100 - 120)*0.5 = -10 USD
ROI = (100 - 120) / 120 = -16.7%
Session UPL and Session RPL
You can view the unrealized PNL and realized PNL of an option position in the current session (last 8:00 UTC to date) on the positions page by checking [session UPL] and [session RPL].
Session UPL is the profit and loss on an open position since last settlement time.
Session RPL is the profit and loss on a position due to close trading since last settlement time.
Session UPL = (mark price - session average price) * position size (coin)
Session RPL = (close price - session average price) * close trade size * (-1)
Session UPL and session RPL will be cleared at 8:00 UTC each day and a new session will begin.
Example
Amy has the following options position.
A short position in a BTCUSD put option expiring in the following month, with a size of 2 BTC and a session average price of 600 USD.
Amy then close buys the BTCUSD option at 800 USD, at which point the mark price is 700 USD and the session average price of the position is still 600 USD.
Then Amy’s current session UPL and session RPL at this time are as follows.
Session RPL = (close price - session average price) * close trade size * (-1)
= (800 - 600)* 1 * (-1)
= -200 USD
Session UPL = (mark price - session average price) * position size (coin)
= (700 - 600) * (-1)
= -100 USD
Note: Realized profit and loss on BIT options contracts will be settled daily at 8:00 UTC while unrealized profit and loss will be cleared after daily settlement.
Realized profit and loss: When a user reduces or closes a position, realized profit and loss will be generated for each reducing/closing trade and will be settled to the cash balance at 8:00 UTC each day.
Unrealized profit and loss: it is for reference only and will be cleared after daily settlement.
