Help to make an indicator!

 

Hello. Here is an index indicator. Can anybody make that:

I can write into this 2 currency index. for example: EUR and GBP ( x, y)

The formula: (1/GBP)*EUR

(1/x)*y

Sorry about my bad english. Pls someone make this indicator, it will be good for analyse divergencia.

Thx

Zoli
