Export a Strategy with Indicator without source code

[webus]

I want to export a Strategy. This Strategy uses an Indicator without source code. When I'm trying to export the Strategy - I see the error. Please take a look at the screenshot. How can I export the Strategy correctly?

Hello webus,

Add a reference to the indicator assembly dll.

From the drop-down select References. Then select the reference.

After the package is exported, drag and drop the assembly dll into the export .zip file.

Below is a link to a video that demonstrates.

The links to the help guide don't show this specifically, but can still be helpful.

Hi NinjaTrader_ChelseaB,

Sorry, but I see the same error when I'm trying to add the indicator as a Refference.

Hello webus,

The error states that not all components have been added.

What indicators or classes does your script call.

Please list of all them.

The Strategy uses 'NordmanMainDivergencesIndicator1v2' (this is a custom indicator, I do not have the source code). I replaced it instead of Fast and Slow MA (the strategy worked on the intersections of these indicators, I replaced these MAs with Arrows from the new indicator). With Fast and Slow MA - I was able to export the Strategy without any problems. So, I do not think that the problem in classes. I any case, the Strategy uses:

All custom classes are described in the strategy itself. Let me remind you that I can easily export the version of the strategy with standard indicators.

Hello webus,

" Let me remind you that I can easily export the version of the strategy with standard indicators."

This is a clear indication that something isn't included.

What classes and indicators does NordmanMainDivergencesIndicator1v2 call. Please list all of them.

If you comment out the line 'NordmanMainDivergencesIndicator1v2 glNordmanMainDivergencesIndicator1v2;' are you able to export?

I do not know, I have no sourse code.

Ok, I've made a simple example from scratch. Please take a look at the video below. Here is what I've done. I opened standard EMA indicator. Then saved it as 'EmaCustom'. Then exported it as a compiled assembly. Then I deleted the source code for the 'EmaCustom'. Then imported the 'EmaCustom'. Then created a simpliest Strategy (you will see it in the video) and added the 'EmaCustom'. I tried to export this new Strategy - the same error. This Strategy does not use any additional classes or indicators. Just the EMA. Can you please make these steps on your side?

If you comment out the line 'NordmanMainDivergencesIndicator1v2 glNordmanMainDivergencesIndicator1v2;' are you able to export?

Yes, I can. I think that the problem is in the NT8 platform. It cannot export a Strategy with an Indicator without source code. Please take a look:

[NinjaTrader_ChelseaB]

Hello webus,

Your video does not show the full process and does not show what code is in EMACustom.


"I think that the problem is in the NT8 platform. It cannot export a Strategy with an Indicator without source code."

This would be incorrect.

Below is a link to a video that demonstrates.
https://drive.google.com/file/d/1Emw...usp=share_link

If you follow the exact steps shown in the video using 8.0.27.1 the behavior is different than what is shown in the video I have provided you showing it works without issue?


The issue you are having is the NordmanMainDivergencesIndicator1v2 is calling another script or class that also needs to be included with the export.

If this is not your script, then you need to contact the author and inquire what classes and indicators are called by their script.

Ok, you want me to make these steps again. Let's focus on the 'CustomEma' issue only. Please take a look. I did not share all indicators/strategies on my terminal, sorry. I think this is not crytical. Here is the video:

using 8.0.27.1

My NT8 version is '8.0.22.2 64-bit'.
upd: I have updated it on '8.0.27.1 64-bit' - the same error, but I do not want make the same video. Hope this is OK.

The issue you are having is the NordmanMainDivergencesIndicator1v2 is calling another script or class that also needs to be included with the export.

Sorry, but the 'CustomEma' does not have any classes or scripts - but it cannot be added also. Let's focus on the 'CustomEma' example from the video above.

Hello webus,

Parts of the video are blurred and hard to see what is going on.

That said, you may have something imported that may be causing an issue.

Try creating a clean environment folder to test.

Below is a link to a forum post with instructions.

If you are following the exact steps as shown in the video using 8.0.27.1 (and not 8.0.22.0) and the behavior is different than is what is shown in the video in a clean environment folder, I would like to schedule a call with you so that I may test these steps on your end.

Thank you, we have a great progress. I've created a clean environment folder to test this - and now everything exports as it should (I don't even have to add the Reference - the platform itself adds it to the archive). I've made a video, but I think this video is not needed.
However, I see another error about accesing to the some file. Is this a critical error? Please take a look at the videos:

Error on 3:54:

Error on 0:27:

Thanks for your support. Have a nice day!

Actually this does not help. However, the archive is seems OK. I can import it without any problems.

Yes, I know. I thought you want to see all steps.

Hello webus,

To confirm, the permissions are changed for EVERYONE to have Full Control but the error is still occurring?

May I have a screenshot of the Documents\NinjaTrader 8\tmp\ folder permissions to confirm?
