[amibroker] finding pivot values using zig

["epintoem" <epintoem@xxxxxxxxx>]

here is what I am trying to do....
the stocks that I am dealing with have an adx(14) of over 25 
I am trying to locate the high for the prev move and the low

here is what I have got...

ab=Zig(C,5);

ah=ValueWhen(ab>Ref(ab,-1),H,1);
al=ValueWhen(ab<Ref(ab,-1),L,1);


This exploration give me only one correct value be it the high or low...
any suggestions?

Thanks
