Zig zag cum volume

AFL Programming
1

Hi,

I've been playing around with an old code of reinsley's. Wave volume using zig zag. I'm trying to plot a shape when "current swing volume > previous swing volume and previous swing volume > swing volume before that...etc". I started writing something at line 69 (where the error shows) ...not sure what comes next. Grateful for any help please.

This line is wrong, it should be

if( <condition(s)> )
{ 
// code
}

hi
Maybe we can give you little bit kick start here.
i would like to remind you that Peak() and Trough() has a third parameter

SYNTAX : Peak(ARRAY, change , n = 1)
n =1 would return the value of the most recent peak.
n =2 would return the value of the 2nd most recent peak.
