Exporting compiled strategies - .cs file exists

[darrentate]

What's the easiest way to incorporate .cs files into your strategy so that when compiled (as protected code) and then exported to another user they don't run into an error because they already have say the EMA.cs sitting on their machine and it can't be overwritten?

Obviously it's not a problem if you can view the source code / unprotected.

Hello darrentate,

Thank you for your post.

You would not run into this error with the system indicators like EMA. However, custom indicators will result in errors like the one you mentioned. You must remove the custom indicators from the installation before being able to import a protected assembly with those same indicators in it.

Hi there -

The only indicators that are used (and that are requested by the system to be added on export) are:

4x moving averages (EMA.cs, HMA.cs, WMA.cs, SMA.cs)
Swing.cs
MIN.cs
MAX.cs

However when I try to import it elsewhere I get:

"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".

There are no other custom indicators referenced in the file. I also double checked that were no previous versions of the same strategy / indicator on the system.

If I bring up references there are various ones that are listed specific to this machine but none of them are used in this strategy.

Hello darrentate,

Is the strategy still in it's .cs source file form in the installation you are trying to import the protected assembly in?

Hi Patrick,

Not that I can see (and I deleted the old versions). I've double checked NT7/bin/Custom/Strategy as well.

Hello darrentate,

Would you mind sending the .zip to me to test on my end?
You can send it to paltformsupport[at]ninjatrader[dot]com with this thread referenced in the body of the e-mail: "http://www.ninjatrader.com/support/forum/showthread.php?t=72450"

Hello darrentate,

Thank you for sending that file over.

There is no issue with the export or import however, the issue is with the other assemblies in your installation. NinjaTrader will attach these to the exported assemblies in a means to ensure the next user who imports has the same assemblies in their installation.

So the solution is to export your files from a "clean" installation, this just means an installation without other assemblies referenced.

Ah great thanks so that means delete the references and the indicators that reference them then export?

Hello darrentate,

Thank you for your response.

You can remove the assemblies via File > Utilities > Remove NinjaScript Assembly.

However, another way to do this without losing your assemblies is to create a development installation that does not contain the assemblies. To do this, go to Help > License Key and copy and paste your License Key into a text document> then shut down NinjaTrader > uninstall NinjaTrader via Start > Control Panel > Programs and Features > once complete go to (My) Documents > rename the 'NinjaTrader 7' folder to 'NinjaTrader 7.Prev'.

Then re-install from the following link: http://www.ninjatrader.com/download-free.php

When you start NinjaTrader it will create a new directory in which you can move over any indicators or strategies you wish to export in this "clean" installation.

To switch between the two installs; shut down NinjaTrader > rename the new installation to 'NinjaTrader 7.Dev' under (My) Documents > then rename the 'NinjaTrader 7.Prev' to 'NinjaTrader 7'.
