Custom Resources in Plots

[stevenev1]

Developing a new indicator, in NT8.

I see that there are custom resources, e.g.
NinjaTrader.Custom.Resource.NinjaScriptIndicatorDi ff

and there are 'magic' ways to assign values to them, e.g.
Diff[0]

Can you please explain how these custom resources work. Are they something that are created by NT, and it is simply exposed for us to use. Also is there a list of them, and list of values that need to be assigned to them

Hello,

Thank you for the inquiry.

The custom resources are used for internal strings in the platform and are not for assignment. These should generally not be used in your own files. You will see these in stock indicators properties and names, but items you may find online may contain them as well. Using invalid resource names can lead to performance impacts so it would be a good idea to just use a string instead.

For example:

this would be invalid because MyPeriod is not a custom resource.

[Display(ResourceType = typeof(Custom.Resource), Name = "MyPeriod", GroupName = "NinjaScriptParameters", Order = 0)]
public int MyPeriod {get;set;}

instead you can remove the resource type all together:

[Display(Name = "MyPeriod", GroupName = "NinjaScriptParameters", Order = 0)]
public int MyPeriod {get;set;}

Another example would be in file naming:

These would be valid for the SMA, because they provide a string for the Description and Name specifically for the SMA.

if (State == State.SetDefaults)
{
	Description = NinjaTrader.Custom.Resource.NinjaScriptIndicatorDescriptionSMA;
	Name = NinjaTrader.Custom.Resource.NinjaScriptIndicatorNameSMA;
}

For a custom item, you would instead use a string:

if (State == State.SetDefaults)
{
	Description = "Some Description";
	Name = "MyCustomName";
}

Diff[0] would likely be a Series in the script you are working with which is a different concept: http://ninjatrader.com/support/helpG...ightsub=series

I look forward to being of further assistance.
