[EquisMetaStock Group] Re: Linear Regression / Linear Regression Slope Relationship

["Jose" <josesilva22@xxxxxxxxx>]

Roy, maybe this will help:

=======================
Lin Reg Indicator/Slope
=======================
---8<---------------------------

{ User inputs }
plot:=Input("[1]LinReg Indicator,   [2]LinReg Slope)",1,2,1);
pds:=Input("LinReg periods)",2,2520,21);
x:=Input("use Open=1, High=2, Low=3, Close=4, Volume=5",1,5,4);
x:=If(x=1,O,If(x=2,H,If(x=3,L,If(x=4,C,V))));

{ Linear Regression components }
y:=pds*Sum(Cum(1)*x,pds)
 -Sum(Cum(1),pds)*Sum(x,pds);
z:=pds*Sum(Pwr(Cum(1),2),pds)
 -Pwr(Sum(Cum(1),pds),2);

{ Linear Regression Slope }
z:=If(z=0,.000001,z);
LinRegSlp:=y/z;

{Linear Regression Indicator (LinReg end-point)}
LinRegInd:=LinRegSlp*Cum(1)
 -LinRegSlp*Mov(Cum(1),pds,S)+Mov(x,pds,S);

{ Plot }
If(plot=1,LinRegInd,LinRegSlp)
