[EquisMetaStock Group] Sigma Bands

[superfragalist <no_reply@xxxxxxxxxxxxxxx>]

This is as close as I can get to true Sigma Bands without using the 
Hurst equations. Hurst math requires C++ and a dll or two. This is 
close enough that it approximates Hurst very well. The defaults work 
okay.

s1:=Input("Smoothing Periods",2,50,10);
r:=LinearReg(C,pds);
x:=Mov(r,s1,S);

x1 :=x+1*Stdev(C,a); 
x2 :=x+2*Stdev(C,a);
x3 :=x+3*Stdev(C,a);  
  
y1:= x-1*Stdev(C,a);
y2:= x-2*Stdev(C,a);
y3:= x-3*Stdev(C,a);
