  Subject: [amibroker] Help with coding Head And Shoulder


  I am trying to code the H&S pattern into Amibroker. I want to have 
  it recognized on the CCI. I coded it, but cannot get it to recognize 
  properly. Here is the code, if anyone can help, I would appreciate 
  it.

  thanks,
  Dennis

  z= CCI(14);

  Plot(z,"",colorSkyblue,styleLine);

  Plot(z,"",colorLime,styleHistogram);

  Plot(0,"",colorRed,styleLine);

  //---------------------------------------------------

  // Head and Shoulders Pattern: to use with CCI(14) with zero line 

  // calculate left shoulder

  LStop= z== HHV(z,(BarsSince(z<0))) AND z>=0 ; //left shoulder top

  LSbot= z==LLV(z,BarsSince(Lstop))AND z>=0 ; //left shoulder bottom

  LeftShoulder= LSbot; //left shoulder

  // calculate head

  HeadTop= z==HHV(z,BarsSince(LSbot)) AND z>=0; //head top

  HeadBot=z== LLV(z,BarsSince(Headtop)) AND z>0; //head bottom

  Head= headbot; //head

  // calculate right shoulder

  RStop= z==HHV(z,BarsSince(Headbot)) AND z>0; //right shoulder top

  rsbot= z==LLV(z,BarsSince(RStop)); // right shoulder bottom

  RightShoulder= rsbot; //right shoulder bottom

  //----------------------------------------------------------

  // Plot numbers for refernce to aid in testing

  PlotShapes(IIf
  (Leftshoulder,shapeDigit1,shapeNone),colorTurquoise,0,0,-15); // 
  left shoulder bottom

  PlotShapes(IIf(Head,shapeDigit2,shapeNone),colorTurquoise,0,0,-
  25); //head bottom

  PlotShapes(IIf
  (rightshoulder,shapeDigit3,shapeNone),colorTurquoise,0,0,-35); // 
  right shoulder bottom
