Percentages

[[Deleted]]

Hi everyone ...

I'm trying to find out how to get variation percentage for prices in relation to their last day close ! In my routine, it's more important to have percentages than absolute values. I couldn't find any configuration that could give me this. Has anyone got any idea ? Is there any script for this ? any way of doing this ? I've tried to create a script or indicator but it's so hard for me

Thanks so much for any help ...
