1. What information is behind the accordion after we click Unrealized Profit?

When you click on Unrealized Profit, you see an accordion sign in front of some securities. If you click on that accordion (which looks like a black triangle) you see a list of transactions.

Clicking on according shows transactions during the explainer time period

Those are transactions done in between the Start Date and End Date of the Explainer calculations. The mtm of each individual transaction is also shown.
