    Question regarding indicator development

    If I'm trying to create an indicator and define the variables

    private double sma = 0;
    private double k = 0;

    And then in my OnBarUpdate(), I write

    k = StdDev(5)[0] / StdDev(10)[0];

    My next line I want to write sma = k times sma from one period ago, but I'm not sure how to call the value of sma from one period ago if it's a variable I've defined. Any help would be appreciated.

    Thanks,
    Lee

    Lee, this would not be possible if you use just a double value - to access the series / history of a double you need to use a DataSeries object - http://www.ninjatrader.com/support/h...ries_class.htm
