[EquisMetaStock Group] Re: Linear Regression

Rick,

Bollinger Bands use the stdev() function to calculate the upper and
lower bands. The middle band is a 20-period simple moving average. Here's the formula.

Periods:=input("Enter the number of periods: ",5,50,20);
A:= Close 
X:= mov(A,Periods,S);
X + ( 2 * stdev( A, Periods ));
X - ( 2 * stdev( A, Periods ))


Modifying this formula may be what you need. The question is the straight linear regression line going through closing prices. You didn't mention how many closing prices.

I'd like to build the indicator and parallel lines so that I could use them in explorer.  Can anyone tell me what function I would use? I can find a way to use linear regression for bands, but not straight lines.   Any help or pointing in the right direction would be appreciated.
