Indicators with multiple pairs doesn't work on my MT4 platform!

[stock78]

Hello there,

 I have tried some indicators such as :

https://www.mql5.com/en/code/9397  , that are extracting data from multiple pairs.

and the problem is that is shows just a flat line in my charts. Also I have coded some indicators myself which are deriving data form multiple pairs but none of the are working. I was wondering if any one has any idea.

 

Thanks.
