Indicator as input series for strategy not working

[ceeb69]

Hey,
I found divergence engine indicator in a discord group and tried to build it in a strategy, It uses input series to select indicator (oscillator's) to show divergences . but when i used in strategy script its not showing indicator as input series in "data series". i had no issues in standalone indicator. After goin through forum, found out i should use it in "state. Configure" instead data loaded but I don't know how to do it . Tried this

 [NinjaScriptProperty, Display(Name = "External Indicator", GroupName = "EXT INDICATOE", Order = 17)]
        [PropertyEditor("NinjaTrader.Gui.Tools.InputEditor")]
        public Indicator indi
        { get; set; }​

its showing in parameters, But giving object don't have instance error and its not calling oscillator .
Please Help

Hello ceeb69,

Selecting an indicator from a drop-down would not instantiate an instance of that indicator. You would need to call the indicator method to instantiate an instance of the indicator.

If you are trying to switch between indicators in the logic, we would recommend using an enum for this.

Below is a link to the help guide reference sample which demonstrates.
