Hi folks,

I am fairly new to options trading and learning the ropes using the paper account. I bought a spread for FB: BUY 2 CALL@350, SELL 2 CALL@360 to be sold on Oct'15 2021. The account window shows this in the `Portfolio` section:


The current price of FB is 328.08 USD. How is Interactive Brokers calculating the Unrealized P&L? Shouldn't this be (Current price - Call strike)*200 + Commissions = (328 - 350)*200 + commissions? If this is the case the unrealized P&L must be higher than what it is shown now. Any help and pointers will be greatly appreciated. Thanks!

I remember a while back that TWS showed different P&L on different windows, and sometimes used the previous close as the basis instead of the most recent price.

I don't know what they do these days but I ended up ignoring their stats and calculating my own. The docs may provide a clue and maybe others have solved the puzzle for the current TWS and can give you some info.
