SUM method in LinReg

[GKonheiser]

Hi There,

I need to modify/ Duplicate and Modify the LinReg method. In LinReg there is a method called SUM that takes 2 pars , a Series and an Int, can I assume that that method give the sum of all the input Series for the number of bars back equal to int ?


Here is the line it appears:-

double slope        = ((double)Period * sumXY - sumX * SUM(Inputs[0], Period)[0]) / divisor;

Hello GKonheiser,

Thank you for your post.

Correct, this would be the sum of the number of bars set by the period parameter. You can find information on the Indicator Methods at the following link: http://ninjatrader.com/support/helpG...indicators.htm

Please let me know if I may be of further assistance.

Thats great thx.

So fi I wanted the sum of the last nine closes excluding the current bar I would use:

SUM(Close, 9)[1];
