RE: [amibroker] Plot Regression Line

["Herman van den Bergen" <psytek@xxxxxxxx>]

// Copied from the list sometime ago...I think Ed wrote the code

per = Param("LinearRegression Period", 8,2,50,1);

mm= (H + L) / 2;

x = Cum(1);

lastx = LastValue( x );

selv = SelectedValue(x);

aaa = LinRegIntercept( mm, per);

bbb = LinRegSlope( mm, per );

daa = SelectedValue(ValueWhen( x, aaa, 1));

dbb = SelectedValue(ValueWhen( x, bbb, 1));

xx = IIf(x > selv - per AND x <= selv, x - (selv - per),Null);

yy = daa + dbb * xx;

Plot(yy, "LinReg", colorBlue );

Plot(C,"",colorWhite,64);

Subject: [amibroker] Plot Regression Line

Hi,

 

Can anyone help me code the program that plots the past 15-day regression line on the chart?  Also, I tried to let the regression line ends with the cursor line.  For example, if I place the line on Dec 6, 2004,  it can show up the 15-day regression line ends on that day.  (Please see the chart below.)

 

 

Thank you for the help in advance.

 

Best regards,
Robert
