Non-optimizable Inputs

[tornadoatc]

Hello,

Is it possible to create Inputs in Ninjascript and mark them somehow so they are not optimizable?

I have inputs for PeriodType and Period Value which I want to use in StrategyAnalyzer for Backtesting. This works fine now, but when I switch to Optimization I get an error stating that I am trying to optimize using Dynamic bar definitions.

For instance, I am using the following to define the parameters:

[Range(0, 6)]
[NinjaScriptProperty]
[Display(Name = "SI_LTPeriodType", Description = "Input System Discovery: Long Term Chart Type", Order = 1, GroupName = "StratDiscConst")]
public int SI_LTCPeriodType
{ get; set; }

 [Range(0, int.MaxValue)]
 [NinjaScriptProperty]
 [Display(Name = "SI_LTPeriodValue", Description = "Input System Discovery: Long Term Chart Period Value", Order = 2, GroupName = "StratDiscConst")]
 public int SI_LTCPeriodValue    
 { get; set; }

And using these parameters in the AddDataSeries()

switch (SI_STCPeriodType) 
{
        case 0: // Tick 
                 AddDataSeries(BarsPeriodType.Tick, SI_STCPeriodValue);
                 Print("Adding STC Tick Bars: " + SI_STCPeriodValue);
                 break;
}

Thanks,

Hello tornadoatc,

Thanks for your post.

Dynamically adding data series is not fully supported (please notes in AddDataSeries documentation.) If you experience an issue that would require our support, the data series should be hard coded when testing to rule out adding the data series dynamically.

If you would like to prevent a parameter from being optimized, you can remove the [NinjaScriptProperty] attribute from the property.

Please let us know if we can be of further assistance.
