LinReg and LinRegSlope are not the same.
Try this.
Period=52;
X=Close;
LinReg=( Period * Sum( Cum( 1 ) * X,Period ) -
Sum( Cum( 1 ),Period) * Sum( X,Period) ) /
(Period * Sum(Cum( 1 )^2,Period ) -
Sum( Cum( 1 ),Period )^2 ) * Cum( 1 ) + (MA(X,Period) -
MA( Cum(1 ),Period) * (Period * Sum( Cum( 1 ) * X,Period) -
Sum( Cum( 1 ),Period ) * Sum( X,Period) ) / (Period *
Sum( Cum(1 )^2 ,Period) - Sum( Cum( 1 ),Period )^2 ) );
Graph1 = 200*(LinReg-Ref(LinReg,-26))/C;
