Hi,
Indeed there is one problem with variable-period sum( array, range ) function:
it is sensitive to the values stored in range array.
Therefore additional check for range value being empty is needed
as shown in the example below:
x = peakbars( close, 10, 1 );
range = IIF( isempty( x ), 0, x ); // this check ensures that range is NOT empty.
graph0 = sum( v, range );
Best regards,
Tomasz Janeczko
