Ruler tool in investing account

Do you guys know if there is among the tools in the graphs, a ruler one, like tradingview, in order to select a precise period of time to measure the correct percentage of that timeframe?

I tend to use the crosshair with tooltip. it lets me drag a line between 2 specific points on the chart to see the change for that window. I think the bottom most option in that cursor dropdown may be what you are looking for.

Thanks Dao. I think that a ruler could be quite handy. But I understand the solution you are suggesting
