Currency strength index

I tried to find a quality “currency strength index” indicator on this platform. The indicators were not what I expected. So I decided to make one (without any programming skills in Pine Script). I added to the DXY (U.S. Dollar Index) the other indexes and all together became a “currency strength index”. What do you think guys?
For this you need another monitor or to switch between the pages but is still something:)

Have a nice day!
