Here's a script to convert indicators and strategies

[miroslav]

Hello,

I had similar issue. You need to have .net frame.4.5 or higher. Download idealy .net frame 4.6 and you should be ok.

Getting a few errors in preparation

Hello, I have done the LinqPad download and modified your script as described. When I load the script I get an error that says that "System.Resource.ResourceManager 4.0.0 requires NuGet client version 3.0 or above, but current NuGet version is 2.8.50926.602. How do I get the newer version, or is there some other issue that I have???

Then, when I run the script I get an error that says the 'CodeAnalysis does not exits in the namespace 'Microsoft'.... THis is all foreign to me, but I can usually hack my way through issues...

Thanks
Bob

Hello maaz1598,

Thank you for your post.

There would not be a Dispose for indicators, you would instead use the State or Terminated to process any clean up: http://ninjatrader.com/support/helpG...n-us/state.htm

mysterious disappearance

i tried the conversion to NT8 it worked perfectly fine for all my strategies expect for one indicator(actually 3 indicators but i dont care about the other 2 ), its not a default NT7 indicator i tried in many different ways to convert it but it dosnt seem to work it keeps giving me error that it cant find anything to override a method called "protected override void Dispose" with my very basic knowledge of C# i cant find this ghost method called Dispose
it seemed to disappear mysteriously?
some one please take a look at it

thank you in advance

The request a cancellation

Excuse me, please! The request a cancellation.
It appears NT7 has accepted ZLRAlert from NT6.5
It is simple magic what that. I suspect NT7 is secretly in love in Woodie'sCCI.
This real magic.

Convert indicator ZLRAlert for NT6.5 in NT7

Hello
If not will complicate, is possible to convert indicator ZLRAlert for NT6.5 in
NT7... Well and for NT8.
Beforehand - huge thank!

Hello Kuvala,

Thank you for your post and welcome to the NinjaTrader Support Forum!

It would be recommended to start a new thread for new items in the future.

For your errors double click on each and take a screenshot of the line of code that is highlighted. Attach the screenshots to your response.

Here is the syntax for the NT7 indicator. Use the converter and observe the changes. What is confusing to me is the regions in NT8 that are different and not addressed in the NT8 Changes links where the line by line syntax changes are spelled out, but the region changes are not. Note; there is little proprietary about this code as it is simple enough and provides no strategy.

Let me get back to you on this. I haven't even opened Ninja in a few weeks as I have been trading with Rithmic these days.

Best regards,

Dolfan

[aligator]

aligator, can you tell me about some of your minor coding solutions? I made an indicator in NT7 that works quite well and seemed to convert using the aforementioned tool here but it doesn't work in NT8. The Ninja team was a great help in my initial NT7 efforts but now, with NT8, the ipso defacto response has turned into, "here is a list of programmers you can hire to help". Needless to say I am frustrated with it.

Understanding the simple line item changes as displayed in the forum is simple enough and the tool makes it even easier but there are structural changes to the code that are not addressed that have me stumped. For example, there are regions changes that are not outlined in the code changes. I feel like this is where my problem lies but there is little support to help me solve this issue.

Thanks for any insight you can provide.

Best regards,

Dolfan

I basically use this tool to convert indicators from NT7 to NT8, then compile and try to address the errors, most of which are related to rendering, text, and graphics. My coding skills are limited, so I dig in whatever documentation available and try to find something similar, then play with codes. I do not have strategies and fixing indicators is not really that involved.

Cheers!

p.s. I know little about regions but If you wish, I can take a look at your indicator and see if I can get it to work in NT8. Having a 35 years collection of indicators, I have no interest in using your intellectual property - just to help, if I can.

Thanks so much for your assistance Serialcoder!

I apologize for not responding sooner. For some strange reason, I have not been getting emails about new posts.

Aligator,

Do you still have issues with conversion? Let me know and include the stacktrace and I'll look into it.

Wil

Thanks Wil, I have managed to get some indicators converted, a slow learning curve though, but your tool has been great and requiring only minor coding to make things work.

But there are some pesky tricks for rendering and drawing. For example, I can not find any documentation for StringFormat to covert the following one line of code from NT7 to NT8:

private StringFormat stringFormat = new StringFormat();

Cheers!

[Dolfan]

Sorry I missed this question Patrick. I've all but given up on Ninja at this point since I found some really nice features in Rithmic that I am now utilizing. I think I got an answer from someone else that explains how much Ninja is working on putting together NT8 and are not yet at the point that I would like as far as NT7 like menus and instructions on creating script. There are areas that are constructed differently in NT8 that are not fully explained, yet, so I wait with breathless anticipation for that day.

Best regards,

Dolfan
