Dashboard: How to show the tendency of a chart?
I hope my question is clear, English is a second language for me. I was wondering if any of you have tips as to the easiest way to indicate the tendency (like the stock market per exemple) on a chart on a dashboard? Is it possible at all or is there a widget or a way to do a calculation in a sheet that could lead me to the same result? If possible, I would like to include the red or green arrow depending on the loss or gain on the chart.
P.S - I only took GameStop stock for the sake of the example, I'm not in finance at all.
Thank you all for your help, this community is really great!
