Is it possible to automatically scan through a list of stocks in a portfolio or watchlist like having a slideshow? If not, is it possible to view charts for each symbol by just simply pressing a down or up arrow key?

I have not yet purchased PSM and my trial period already expired. So I can't test to see what features are available. Thank you.

Yes, the chart window has left and right buttons that allow you to easily scroll through your list of tickers.
