In my first article, using the Hilbert Transform, I showed how the technique could be used for measuring the cyclic content in prices at any given bar on your chart. This, in turn, I used to create an indicator showing you what the cyclic content was and, inferentially, whether you were in a cycle or trending pricing mode. I also included a signal-to-noise ratio computation so you could estimate whether there existed enough signal in the pricing activity to justify trading on the cycle content. Since the article was published, I\'ve come up with a simpler expression for achieving the same result and with slightly less delay.
The revised TradeStation code is:
Code:
Typ : Indicator, Name : Hilbert Transform
Inputs: Price((H+L)/2);
Vars: InPhase(0),
Quadrature(0);
If CurrentBar > 5 then begin
Value1 = Price - Price[6];
Value2 =Value1[3];
Value3 =.75*(Value1 - Value1[6]) + .25*(Value1[2] - Value1[4]);
InPhase = .33*Value2 + .67*InPhase[1];
Quadrature = .2*Value3 + .8*Quadrature[1];
Plot1(Inphase, \"I\");
Plot2(Quadrature, \"Q\");
end;
