Calculating Profit or Loss After an Assignment or Exercise

Reconciling your portfolio after being assigned or exercised is quite simple. Assuming you have closed your position, follow the sections below to learn how to use the History tab in the desktop platform to calculate the P/L.


Options Spreads

Locate the opening order, include any rolls, assignment, and the closing order

Whether a spread was early assigned or held to expiration, you can reconcile your P/L using the same method below. If you were assigned early on a spread and later closed out of the assignment with a covered stock order, then you have all the components needed to calculate your overall P/L of a position. The same applies with an ITM spread held to expiration that was assigned and exercised. The step-by-step instructions below apply to all spreads and situations, as long as the position is completely closed. 


Below, we have an example of a short TSLA Mar 1 -317.5/+315 put spread initially sold for a $1.00 credit then rolled for a $0.49 credit. Later, the short put -317.50 was assigned and closed resulting position was closed the next day as a covered stock order.

  1. Head to the Activity tab to see when you initially opened the position–this will make it easier when you go the History tab.
  2. After you find out when you opened the position, go to the History tab and use the Symbol Filter to isolate the symbol and select a Date Filter or select a Start Date of when you initially opened the position.
  3. The History tab will list all the associated transaction and add everything listed. However, if you have overlapping transactions, as illustrated below, then you may select each line item, and the History tab will do the math for you. Below, you can see the original opening trade, the rolling trade, the assignment, and closing the assignment with a covered stock order. Listed above the Amount column is the total gross P/L, which in this case is -$355.99.
