I'm creating the following strategy with EMA indicator, but there's an error that I can't fix and I don't know what it is, can anyone help me? Here's the code:

Hello andersja,

Thanks for your post.

It seems that this is a custom Indicator script created for NinjaTrader 7 so I have moved your forum thread from NinjaTrader 8 - Strategy Development to the NinjaTrader 7 - Indicator Development section of the forums.

That said, To clarify, did you program the script yourself? Or, was the indicator you shared programmed by a third-party developer?

What NinjaTrader version are you using? (NinjaTrader 7 or NinjaTrader 8) This could be found by going to Help > About on the Control Center.

Is the error message related to using AddPlot() in your custom NinjaTrader 7 indicator?

AddPlot() can only be used in NinjaScript strategies in NinjaTrader 7.

To add a plot to a NinjaScript indicator in NinjaTrader 7, the Add() method must be used.

Further, Brushes is only used in NinjaTrader 8, not NinjaTrader 7. Color would need to be used in the Add() method to set the color of a plot in NinjaTrader 7.

See this help guide page for more information about using Add() to add a new plot to an indicator in NinjaTrader 7: https://ninjatrader.com/support/helpGuides/nt7/add.htm

If this is not the error you are referring to, please send me a screenshot of the error message you are referring to so I may accurately assist you.

I'm using ninjatrader in version 8.0.28.0. I made the script myself

Hello andersja,

Thanks for your notes.

In the code you shared in post # 1 I see you are using protected override void Initialize() which is only used in NinjaTrader 7, not NinjaTrader 8, which is what led me to believe this was a NinjaTrader 7 script.

Note that NinjaTrader 8 uses OnStateChange() instead of Initialize().

In the code you shared on post # 4, I see you are instantiating variables and calling AddChartIndicator() in State.Configure. The script should be modified so that the indicators are instantiated in State.DataLoaded and AddChartIndicator() should be called in State.DataLoaded.

AddChartIndicator(): https://ninjatrader.com/support/help...tindicator.htm

See the SampleMACrossover strategy which demonstrates this. To view the script, open a New > NinjaScript Editor window, open the Strategies folder, and double-click on the SampleMACrossover file.

That said, what exactly does the error message state so I may accurately assist (not to be confused with the error code number)?

Also, if you double-click on the compile error, what is the line of code that the error is on?

Please send me a screenshot of the error message you are referring to as requested in my previous post.
