Hello,

Thank you for the post.

In this case, the .net version used in NinjaTrader would not support this syntax as it is from a newer .net version, you would need to just create a property and assign it from the appropriate state. This is a .net 6 feature where NinijaTrader 8 uses .net 4.5.X

public Brush MyBrush {get;set;}

From State.SetDefaults you could set the brush:

MyBrush = Brushes.LightGreen;

When reviewing syntax online at MSDN or using completion tools in other applications like a Visual studio you may run into this. Resharper specifically will recommend this which will create invalid syntax for the version being used.


I look forward to being of further assistance.

Hello,

This would be invalid for the version of .net being used again. The ? (safe navigation operator) would not be valid in NinjaScript. The NinjaScript editor should be highlighting the space between the word and a question mark as red indicating a problem. This is a C# 6 feature also which would not be able to be used in NinjaScript. You would instead just need to check for null using equality:

if(BuyLadderBrushDx != null) BuyLadderBrushDx.Dispose();

If you are using automation tools like Visual studio or other external editors, please be careful as to what syntax you use or allow to be generated as this is not for the correct .net version we are using. External tools that target a higher version of .net will recommend items like checking for null on an object with the safe navigation operator, this would not work with NinjaScript. If in doubt, undo the last changes you had made until you get back to a compiled state, and then try doing a small portion of the change again to find what specifically is wrong.



Please let me know if I may be of further assistance.
