[amibroker] Re: Reverse engineering eSignal ZigZag code

["DIMITRIS TSOKAKIS" <TSOKAKIS@xxxxxxxxx>]

Aequalsz, Stephane,
the following code is not perfect, but catches the majority of the 
zigHiLo points.

// ZigHiLo approximation
Plot(C,"C",1,64);
C2=IIf(H>Ref(H,-1) AND H>Ref(H,1),H,IIf(L<Ref(L,-1) AND L<Ref
(L,1),L,Avg));
Plot(C2,"C2",4,1);
Plot(Zig(C2,5),"Zig",7,1);
GraphXSpace=3;
