Upgrading an Indicator

[moflaherty]

Can I verify the process of upgrading an indicator? If we ship out an exported indicator as a zip (through NinjaTrader's export process), when we need to release an update, can the end-user simply import the new indicator? Or does he or she need to remove the other one first? Or can the DLL simply be replaced?

Thanks!

Hi Michael,

If the name is exactly the same, then you are prompted to overwrite existing files with the same name. If the name is different, then you should instruct the user to delete first so there are not any namespace conflicts.

Hi! I finally got around to trying this. If I export the indicator out using the exact same name (but changing the version number), when I send this to a friend, when he imports the zip, it fails. You get the normal warning message at first, but then the indicator gets this message:

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 file.

This fails from a cold start where no connection has been made yet.

Shouldn't this simply upgrade and replace the files? As you can imagine, if the indicator is used in a number of charts, it is a pain to remove or rem out all references before upgrading.

Thanks for your help!

Hi Michael,

If it's an assembly you're exporting, then you should make sure the importing PC does not also have the source files. If you want to see the exact cause of the programming conflict, manually place the dll in My Documents\NinjaTrader 7\bin\custom and add the reference through the NS editor Right Click > References screen.

When you attempt to compile, it will list the specific errors raised.

I will try this. However, the only code that I am shipping is what is created in the ZIP file. No source code is distributed.
