import error with strategy + indicator

[onnb1]

I am distributing an indicator and a strategy that depends on that indicator. I export the pair as compiled assemblies. When I import them, I am getting a message that:

Import failed: The NinjaScript Archive file may contain duplicate method names that already exist on your PC or there is a required file missing on either your PC or in the import archive.

I've checked that the indicator/strategy do not exist on the PC. I can copy the source files and compile them just fine on that same PC.

Any ideas why this might be happening?

Hi Onn, on the exporting PC are there more assemblies referenced than just the default NT setup ones?

[onnb1]

Not sure what you are asking but let me try and answer. I have an indicator that I created. It only makes use of the default built in NT indicators.

I have a strategy that references that Indicator. I export both of these in one archive.

On the exporting PC, I do have other non-default assemblies but they are not referenced in the indicator or strategy

does this answer your question?

Hello,

I would suggest manually importing the DLL on the destination computer and manually adding the reference to this DLL, then compile your indicators.

This will tell us exactly where the conflict is coming from and help you determine how to avoid this.

You can do this by extracing the DLL files you created and moving to (My)Documents\NinjaTrader 7\bin\Custom

Once they are in this folder, please right click on the NinjaScript editor and select "References" and then select "Add" and then locate the DLL files you are using.

After this has been completed, please compile your indicators and the error should tell us exactly where the conflict is coming from.

Matthew,
I also ran into similar issue with my new pc. I exported as compiled assembly and imported it and no problem but when I went in to edit my strategy and indicators I donot see them in the list. I even tried to load the existing strategy and added the dll and compiled it again but donot see my custom indicators and strategy (source code). but they are running in MA and even enable strategy in the chart. what am I missing

[NinjaTrader_Matthew]

Could it be that they have a different name than the DLL file?

[kinshin9]

yes. how do I get em back ? When we compile different indicators into an assembly how do we name same ?. please help... spent hours developing and now I din;t see the source code..

[kinshin9]

Sorry Matthew, such an ignorent i am. Golden rule " read the manual" ignored and assumed that assembly is "zip" of all indicators. After looking thru some of the posts i realized what a blunder i commited. Now, is there a way to get the code back from assembly. Please please help....
hours of work and my system crashed yesterday and this is the last backup i have. Fingers crossed

Dll is not source code. If you import an indicator/strategy as a dll, you will not be able to edit it.

Unfortunately you will need to find the original source file (.cs) in which the DLL was created from and make these changes there. Once changed, you can reexport as a DLL.

Hi Mathew,

I did as you suggested below and got the following error:

NinjaScript File: Indicator\@ADL.cs
Error: The Type NinjaTrader.Indicator.MyIndicator is define

Ideas?
