Error on creating an indicator dll

[TheChingachgook]

I have some problems in creating an indicator dll.

It seems I don't really understand the help

http://www.ninjatrader-support.com/HelpGuideV6/helpguide.html?Overview48

I developed an Indicator called TE_Entry_FirstHaltAt20 which is located in
C:\Dokumente und Einstellungen\Besitzer\Eigene Dateien\NinjaTrader 6.5\bin\Custom\Indicator

Then I created a file called

C:\Dokumente und Einstellungen\Besitzer\Eigene Dateien\NinjaTrader 6.5\bin\Custom\NinjaTrader.TE_Entry_FirstHaltAt20. cs

There I entered the using-declarations like described in the help and additionally I copied the 'NinjaScript generated code. Neither change nor remove.'-section from the indicator into the NinjaTrader.TE_Entry_FirstHaltAt20.cs

at compile time the following error occures

NinjaTrader.TE_Entry_FirstHaltAt20.cs;Der Typ NinjaTrader.Indicator.Indicator enthält bereits eine Definition für cacheTE_Entry_FirstHaltAt20.;CS0102 - click for info;18;42;

which means :
NinjaTrader.TE_Entry_FirstHaltAt20.cs;Der Typ NinjaTrader.Indicator.Indicator already contains a definition for cacheTE_Entry_FirstHaltAt20.;CS0102 - click for info;18;42;

does anybody know whats wrong what I'm doing.

And why is this process so complicated - a MenuItem 'create Dll' where the necessary step are performed automatically would quite need.

and moving and copying around code is a potential source of errors as well - I think there could be a room for improvement.

[NinjaTrader_Bertrand]

TheChingachgook, you would only need this process if you want to reference a custom assembly in your code - if you don't need this then you can just create a DLL using the standard export procedure - http://www.ninjatrader-support.com/H...6/Export1.html

[TheChingachgook]

Thanks a lot ... but when I try to export an indicator I'm getting an error.


it doesn't recognize some helper classes in the Indicator\UserdefinedMethod.cs which I implemented in the NinjaTrader.Indicator namespace.

Type or namespace 'Pivothandler' couldn't be found (using directive or assembly reference missing)

[NinjaTrader_Bertrand]

This is unfortunately expected for methods defined in UserDefinedMethods - http://www.ninjatrader-support.com/H...verview45.html

Best would be you port this method then to the indicator itself for export.

[TheChingachgook]

It's quite complicated to do a simple thing:

The helper classes I moved into a dummy indicator (TEHelper) and when I'm exporting both of them, then .... it seems ... the compiler will recognize the helper classes.

But whenever I want to access such a class the type has to be exactly quailfied : e.g. NinjaTrader.Indicator.TEHelper.PivotHandler ....


But now I stumple through the next hurdels:

1)

isLineReseted is a protected variable in the UserdefinedMethods Indicator class.

--> this is a Method of the superclass in UserdefinedMethods ... so it seems that everthing what is coded in the Indicator superclass is useless by exporting the code.

but I didn't get any comile-error when I compiled the whole stuff in the IDE.

-->> double atr = ATR(close, 5)[0];

this line causes this compile error.... --- does that mean, that it is not allowed to use system indicators in exported Indicators???

-->> Not allowed to use the SMA


Please help me....

[NinjaTrader_Bertrand]

TheChingachgook, sorry for the frustrations - it sounds like you're having multiple methods with the same names present which causes the conflict. Please try commenting out the ones in UserDefinedMethods that you ported to an indicator for export usage.

3 looks like a coding error as Close should start with a capital C.

[TheChingachgook]

Hi Bertrand

Thank you for your answer.

No I cleaned up the superclass and duplicated the variables and the methods into the different indicators .... but I'm asking me, what is sense of the indicator superclass at all, if it is not allowed to put code in it??

But the issues 3, 4 and 5 are not solved yet.

I changed to code to 'double atr = ATR(Close, 5)[0]' now, but I'm still getting the same error.

but anyway ... also 'double atr = ATR(close, 5)[0]' was compileable in the IDE and the strategy performed this indicator (and this codeline ) already by thousand times -> close is only a dataseries with special close values.

the same Problem occures with every system indicator .. I just tried to use the EMA indicator .... no problem by compiling it in the NTScript editor.

double ema = EMA (Close, 6)[0];


But as soon I try to export this code I get the following errors again:

1)

It seems the problem is located somewhere else!?

[NinjaTrader_Bertrand]

Thanks for your reply, sometimes you have to include explicitly the dependent system indicators for export with the strategy, please check into this link and see if it helps - http://www.ninjatrader-support.com/H...tProblems.html

[TheChingachgook]

it seems it's going to be a longer thread

In this link http://www.ninjatrader-support.com/H...ExportProblems the following issue is mentioned.

3. Under “Export objects”, select “System indicators”


but, when I look at my export dialog only I only see the following object types to select:

All
Indicators
Strategies

the item 'System indicators' is missing.

what might here be the problem - is this configurable somewhere

[NinjaTrader_Bertrand]

Which NinjaTrader version are you running currently? Please ensure you're on 6.5.1000.11

[TheChingachgook]

ooops you are right .... I had not the current version ... what a shame


At this point I really must tell you, that you support guys a doing a great job here ... thank you very much

[NinjaTrader_Bertrand]

You're welcome, thanks for the kind words!

[eDanny]

I have a problem with this solution. Why would having the latest version make a difference? Does that mean everyone having an earlier version will have the same problem? No, of course not. My earlier version works correctly in this regard so why did TheChingachgook not see the “System indicators” while I can? See what I mean? There has been no solution presented here at all.

[NinjaTrader_Bertrand]

If you check into our release notes - http://www.ninjatrader-support.com/H...easeNotes.html

You'll notice item 2689 addresses the issues the poster reported, that's why we asked on which version he was...

[eDanny]

I see, now I noticed my version is the one where the problem was fixed! You are off the hook Bertrand. It's just that I see so many of this kind of post and sometimes I like to see more in depth answers. Sorry bud.
