portfolio performance is not a tracking provider but it can use any other pages to track securities. But that means you have to add the security first, but I had no problems tracking anything I wanted up until now. You usually can use yahoo finance tickers, or if exists anywhere on web like a json or even a standard web page table you can add it, and portfolio performance will read that for tracking.
edit: @adindas The amount of detail you can create in this tool is very deep. When you download it, it comes with a “sample portfolio” I recommend studying it for a while before getting started with yours. It takes a bit of setup time at the beginning, but after going through that it is golden.
I have written here some of my setup (a bit outdated with the CSV download feature)
