The 'Shares Held' tree item under the 'My Portfolios' tab gives you details of the shares held in a particular share portfolio.
There are many columns of data that you can display on this page, and you can choose which to show and which to hide. Right clicking the header of any table allows you to modify the columns shown.
Notice in the example shown, the editable Price Min/Max column for AXA.AX contains a low price above the current price, which causes that line to appear red indicating it has fallen below the minimum price.
In 'Manual Upper and Lower Price Warnings' mode you can edit the min and max price values to your preference. The 'Tools/Options' menu dialog allows you to switch from manual to automatic.
