I wrote an small indicator based on the d9ParticleOscillatorWVertLineR indicator, it compiled with no error and it's works as expected. When I tried to export the indicator, it returns the following error. All my indicators are compiled with no error except when i tried to export the indicator. I have no clue...

I think you need to include d9.NinjaScript.Utility.cs when you try to export a d9 indicator.

thanks Cory. It solved the problem.
