Your dashboards from the previous version of Koyfin are now called watchlists. To access your watchlists, create a new MyDashboard and load your watchlist.

Click on “NEW” in the left menu, Select “Watchlist”, and select your existing watchlist.

The column views in the previous version of Koyfin are now called Templates. Load your saved templates, or create a new one.

You can also use your watchlists in the right-side menu to activate the Graph (G), Snapshot (S) or other functions.

Check out this video which explains the data and functionality upgrades in the new Koyfin.
