ROC Indicator not working

[Zolfagharipour]

Hello dear friends

I am writing an expert and I wanted to use ROC indicator. My problem is in backtesting the indocator doesnt give me any signal and when I read the output in my EA it comes as infinity.
I also tried many different ROC from different websites. would you please help me if you have the same experience?
