iHigh indicator sometimes returning zero

Hi All,

I have a recurring problem. An indicator uses many symbols internally though iHigh function.

IHigh for certain symbols sometimes returns zero. I mean for the same symbol it sometimes works and it sometimes does not. Do you know how to prevent that?

Ok, I figured out I have to open charts that use that same timeframe and symbols..

Is there a better way?

It returns 0 when the specified symbol or TF doesn't have the right data to be returned ...
