Stockfuse provides an interactive, graphical view to show your profits and losses on each of your holdings over time:

• Go to your Portfolio Dashboard;
• Click on the Analytics tab and select P&L Attribution in the dropdown menu.

By default, the chart shows the daily P&L for every stock you’ve traded on over the past month; however, the control strip allows you to customize the chart in many different ways. For example, if you want to know the cumulative P&L on everything you’ve traded since the beginning of time, simply click on the Daily button and switch it to Cumulative, and then change the horizon to All Time.

This feature is currently available only on the web.
