hi kvak

I have an idea
I don't know if it's possible or not, but apparently it's not a bad idea.
I used the idea of opposite currencies
I used 2 obv multisymbol indicators in the eurusd chart, and from one of them I set obv to eurusd and the other to usdind.
I wanted to know if something like this is possible in the form of 1 indicator or not?
And if this combination is between the range, it works better or not.
must see
thank you
