Adding parameters in custom strategy

[cmassey4032]

When I add parameters in a custom strategy with the builder they are available on the strategy analyzer. When I add them on directly to the code they are not available. What am I missing?

Code:

if (State == State.SetDefaults)
{
Description = @"Enter the description for your new custom Strategy here.";
Name = "Craig4";
Calculate = Calculate.OnBarClose;
EntriesPerDirection = 1;
EntryHandling = EntryHandling.AllEntries;
IsExitOnSessionCloseStrategy = true;
ExitOnSessionCloseSeconds = 1500;
IsFillLimitOnTouch = false;
MaximumBarsLookBack = MaximumBarsLookBack.TwoHundredFiftySix;
OrderFillResolution = OrderFillResolution.Standard;
Slippage = 0;
StartBehavior = StartBehavior.WaitUntilFlat;
TimeInForce = TimeInForce.Gtc;
TraceOrders = false;
RealtimeErrorHandling = RealtimeErrorHandling.StopCancelClose;
StopTargetHandling = StopTargetHandling.PerEntryExecution;
BarsRequiredToTrade = 20;
// Disable this property for performance gains in Strategy Analyzer optimizations
// See the Help Guide for additional information
IsInstantiatedOnEachOptimizationIteration = True;
Time = 28;
Atr =.12;
}

The time variable was added with the builder it shows up in the Analyzer.
The Atr variable I added directly into the code it does not.

Thanks!

Hello cmassey4032,

Welcome to the NinjaTrader support forum.

The part of your code you have shown would not be important toward how the analyzer picks up the properties, it is instead where you define the property and the syntax used for the property that matters.

The easiest way to see what is required would be to create a new strategy and generate 1 new property then view its code. The part you provided will be there however near the bottom you will also see a public property that was generated similar to the following:

#region Properties
        [Range(1, int.MaxValue), NinjaScriptProperty]
        [Display(Name = "Period", GroupName = "NinjaScriptParameters", Order = 0)]
        public int Period
        { get; set; }
#endregion

The important part here is the [NinjaScriptProperty] attribute, this is combined with the Range attribute in the above example however you can use just [NinjaScriptProperty] on a property as well.

https://ninjatrader.com/support/helpGuides/nt8/en-us/ninjascriptpropertyattribute.htm?zoom_highlightsub=NinjaScriptProperty

This will control if this public property is used in the optimizer for a range of values or not, omitting NinjaScriptProperty will allow it to still be used as an input just not with optimizable values.


I look forward to being of further assistance.

Perfect! I knew I was missing something because I could not find where Time was defined from the builder code. hidden at the bottom. Many Thanks!
