How to get Max/Min values of ExtMapBuffer[]?

New comment
 

My custom ExtMapBuffer[] is fluctuating between -ve and +ve regions,

For each region, I need to get its MAX/MIN strokes - for the visible bars - in order to be used as EXIT for SELL/BUY positions.

Any suggestions?

 
use mathmax or mathmin function

MathMax( double value1, double value2)

Returns the maximum value of two numeric values, and hence can not be applied on Buffer[]

You could use

and the matching ArrayMinimum function
