Is there an example portfolio file I could download and play with? Would really help me understand whether this a tool that I would like to invest time in.
Thank you!
You could download it and use the included kommer example for testing.
In the comments section of the second video you will find a link to a example file used in the video.
Help, Welcome will display the Portfolio Performance welcome tab which has links to the Kommer and DAX sample [demonstration] files. Once you are happy with them you can follow Guide on getting started or Import CSV file.
