how to save as my watch list
You can just create a watchlist and add items into it. You can take a look at this help page (https://stockalyze.com/help/manual/topics/portfolio-and-watchlist.html) to know the details.
Note: We recently discovered a defect that adding an item without creating a watchlist crashes Stockalyze. We now have fixed it recently. In case you are using old Stockalyze please download afresh (https://stockalyze.com/download/setup.html).
