It is my understanding that Lineareg(c,25) is a plot of the endpoints of a
series of 25 day linear regressions fit lines. (ie the classical y=a+bx
where a is the y-intercept and b the slope)
So this should be it.
x=Cum(1);
b=LinRegSlope(C,period);
// dont use the traditional 'a', as thats a pre-defined identifier (average)
i=(Sum(C,period)-b*Sum(x,period))/period;
Lineareg=i+b*x;
Plot(lineareg,"Linear",1);
Plot(C,"Close",2);
