ZIP Format on Ninja 7

[pmaglio]

Just for curious, Im having troubles to unzip exported indicators and/or strategies on Ninja 7 ; is it using some modified zip format ? ...and if so, something can be done to be able to open those zip files from windows ?

Hello Pmaglio,

Thank you for your post.

There shouldn't be any special zip structure. You should be able to open with any compression software or even the standard windows file manager.

Let us know the error messages you're getting and share one of the files you're having trouble opening. We can help isolate whether the issue is with the files or with your system.

I can see the contents of the zip file, but cant extract the .cs file located inside the Indicator folder. This happens with any ninja 7.0 zip file. Last file I tried was VWAPNT7.zip on this website just to check if the trouble was with my own generated files.
Tried on 2 different PC's with Windows XP service Pack 3 spanish

I've not heard of this issue. Maybe try a separate compression program like winrar or winzip.

I'll see if I can find an XP machine to test the NT7 zip files.

pmaglio,

Can you successfully import this file using File > Utilities > Import NinjaScript?

[pmaglio]

Yes, thats the strange part, My Ninja 7 can import these zip's without any trouble.
But the .cs file inside the "Indicator" folder into the zip can't be extracted with windows or winrar. This happens also with 2 friends who tried to open a zip file I sent to them.
Check this file ( it is just a copy of EMA exported )

pmaglio,

If it imports then it is working as expected. Unfortunately we are unable to support why you can't open the zip in Windows. If you want access to the .cs file you can access it after you have used NT to import in the Documents\NinjaTrader 7\bin\Custom\Indicator or \Strategy folder.

Thanks Josh,

Btw, Is this behavior by design or something is wrong on my PC's ?

[NinjaTrader_JoshP]

pmaglio,

It is not by design. Unfortunately I do not know why you are unable to extract zip files on your machine.

Note to Ninja support folks: I reported this issue in April via email. Please see email thread 308188.

Conclusions seem to be 1) There are customers who were not having problems with .ZIP files in 6.5 who are having an issue with 7; 2) Ninja did make a change in this area; and 3) so far Ninja is stuck on "we can't reproduce it so it's not our problem."

But if I did nothing but upgrade from 6.5 to 7 and now something doesn't work, I kinda sorta think Ninja IS part of the problem....

I have the same problem with NT7. I am using WindowsXP. I can't unpack NT7 zip files (get empty directories as an result). But I can import with NT7 correctly. Never have seen such issue with NT6.5.
Conclusion: In NT7 they use their own zip routines which are not compatible with WindowsXP anymore.

Guys,

Let me try to clarify:
- NT 6.5 had been using an outdated version of a 3rd party component called SharpZipLib. This version had some deficiencies as it e.g. failed to zip a large number of files
- NT 7 now incorporates the latest version of that SW which overcomes these issues. Unfortunately on Windows XP you would experience what you experienced. However there really is not issue as (a) NT properly works using that version and (b) you can work around by using NT to build or unzip these archives.

Thanks

yahoo is marking any ninjascript exported with NT7 as virus. no such issues with NT6.5 though.

We are neither the vendor nor the developer of YAHOO software.Please contact YAHOO to get this issue resolved. Thanks

thanks Dierk for the prompt reply.

by yahoo i am not implying any special software. just the standard mail service of yahoo.

seems the issue has already been raised. http://www.ninjatrader.com/support/f...ht=yahoo+virus

and seems its more sort of a ziplib issue.

thanks again for your time.

regards..
