QQQ TO NQ Indicator (Need help with errors)

[josh18955]

So I have been working on a code that converts QQQ levels to NQ and will make a new indicator that will convert SPY to ES. Reason for doing this is because SPY & QQQ tend to have better volume levels compared to ES/NQ. I have developed a code to convert these levels, but for some reason am getting a error code and for life of me can't figure out what it is. I have imported all the correct 3rd party systems, but still can't figure it out. Any help would be greatly appreciated. Code posted down below. Error code also posted

You have to add reference to namespace where Ticker class is defined. Do you have an indicator that uses this class? Look at declarations in it (where "using" keywords).

Hello josh18955,

Thanks for your post.

This error can occur when an imported DLL (could be a 3rd party indicator) you are referencing no longer exists / has been removed.

To resolve this the DLL must be re-imported.

To re-import a 3rd party dll:

• Open the NinjaScript Editor via New > NinjaScript editor.
• Right mouse click in the NinjaScript Editor main window and select the menu name "References"
• In the "References" dialog window press the button "Add"
• Select the 3rd party DLL

See this help guide page for more information about CS0246: https://ninjatrader.com/support/help...nt8/cs0246.htm

Please let me know if I may assist further.

How do I know which DLL I am supposed to import and where can I find them?

[NinjaTrader_BrandonH]

Hello josh18955,

Thanks for your note.

In the code you shared, you are calling 'private Ticker qqqTicker'.

Ticker is not a C# Keyword like double, int, bool, etc. Ticker is also not a class or indicator that comes default with NinjaTrader. A reference to the namespace where Ticker is being defined would likely need to be added to your script.

Do you have an indicator that uses this 'Ticker' class?

Is this 'Ticker' class from a third-party indicator?

Do you have an indicator named 'Ticker' that you are trying to use in the script? How is 'Ticker' defined in the indicator script you are trying to access?

Let me know if I may assist further.

What was the resolution to this? A DLL reference? If so, what was the DLL?

[Delerium]

I'm curious to know if this was resolved too because I'm interested in an indicator that can do this for NT8. I know of an indicator on Tradingview that will do these conversions but it will cost some $$ to convert it to Ninjascript according to a developer I know.
