I have series with some values. I need to find the lowest or the highest number of the last 30 values of the series.

Is there some function to do it or I have to create my own function?

Something like LL or HH (zorro functions).

MinVal, MaxVal.

Thank you, I couldn't find it in the manual.

I couldn't make it work, because my MinMax period was longer then the LookBack period.

Someone might find this information useful: LookBack period has to be longer then the MinMax period.

I am using the MinMax Zorro function for finding Min and Max values of the series.
