Why default values are not possible?

[ttodua]

hi.
I saw nice solution to set values inline (without scattering variables across different places):

https://stackoverflow.com/a/40754/2377343

however, that seems impossible in NT IDE, gives error:

Invalid token '=' in class, struct, or interface member declaration

even another answer, like :

[System.ComponentModel.DefaultValue(true)]
public bool DefaultValueBool { get; set; }

is not being understood in NT...

Hello TazoTodua,

This would be custom c# code that is not documented by NinjaTrader or supported by the NinjaTrader Support staff.

However, this thread will remain open for any community members that would like to assist.

I've seen now, cTrader supports the "DefaultValue" parameter. Very nice declarations there:


[Parameter(DefaultValue = 70)]
public int My_Level { get; set; }

probably i am not too good in C#, otherwise there should be some "override" or ability to create special attribute for NT to do that with custom programming. Just i dont know how to do that.

Hello TazoTodua,

I think what you are trying to use is part of c# 6 and higher.

NinjaTrader 8 targets .NET 4.5 which is c# 5.

Likely what you are after is not available in this version of .NET.

Instead, set the defaults in State.SetDefaults. This is important for NinjaTrader as the defaults are pulled and applied in a specific way from OnStateChange at specific times.
