Hi,
I can see a couple of problems.
1. You are plotting a ZigZag with a 4% change (second argument to
Zig), but setting your conditions based on a a ZigZag with a 1%
change (second argument to Peak/Trough).
2. You are passing in the result of the Zig indicator into
Peak/Trough which is not correct. Peak/Trough automatically use Zig
upon the array that you pass in. Therefore, you are doing a Zig of
Zig!
You probably want to change your Peak and Trough function calls to
pass the same array as you passed to Zig directly (i.e. Close), and
you probably want to pass the same value that you used when calling
Zig directly (i.e. 4).
By default the 3rd argument is already set to 1 which is what you
wanted (i.e. 1 peak/trough ago). But, for the purposes of
illustration, I'm adding it in.
e.g.
z=Zig(C,4); // Peaks and troughs after 4% movement.
...
Condi1=C<Peak(C,4,1); // 1 Peak ago based on 4% movement.
Condi2=C<Trough(C,4,1); // 1 Trough ago based on 4% movement.
...
Note: I can't actually see your attachments. So, I'm guessing at the
above based on reading your code.
Note: Use caution when working with the Zig indicator. It looks into
the future! So, you cannot use it in a real system unless you delay
your Buy/Sell until AFTER the signals could have been detected
without seeing the future.
