Notes about your trade can be used in your input and they will be displayed with the trade on the website.
Notes are always last. I.e.

Notes are there for you or to show other traders any comments you might have about the trade—it can be analysis, what made you enter/exit a position, such as an earnings report, or anything you wish to add. Notes are displayed on the website in several places. The Trades page, a Trade Insight page, and Dashboards but can be cut off. Full notes will be shown in the dropdown section of the Trades page and on Trade Insight pages.
