Matlab NT integration

[arnold.horvath]

Error on calling 'OnBarUpdate' method for indicator 'BollingerKalmanPairsTrade' on bar 0:
Could not load file or assembly 'TradeSignalITradeSignalBoKal, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies.
The system cannot find the file specified.

Dear Support !

I am in pain. I do not have a clue how to proceed.
My compiled matlab code works like a charm in Visual Studio c#, however Ninjatrader is stuck with the above error.

1) dlls are compiled into .net version 3.5, 64bit, type-safe API
2) I use NT 64 bit
2) they are in the bin\custom directory
3) I restarted NT and reboot the machine, etc.

How can I debug what is wrong ?

Thanks a lot

Hello arnold.horvath,

Thank you for your post.

Is the 'TradeSignalITradeSignalBoKal.dll' referenced in NinjaTrader? When you right click in the NinjaScript Editor > select References > do you see all appropriate references added?

Do all NinjaScript files compile when you go to Tools > Edit NinjaScript > Indicator > select any indicator > OK > and when the NinjaScript Editor loads and you press F5 to compile? Or do you receive any error messages? If so, what do these errors report?

I look forward to your response.

Hi Patrick !

Thank you for the answer.
The dll is referenced and the compilation is without errors.

I made it work in the end, but not the Type-Safe interface way.

The MWArray method is working, no matter how ugly it is with the flood of casts and related exceptions...

You may want to take a look at LabSharp (c# matlab wrapper):

http://code.google.com/p/labsharp/

It is not maintained anymore but with some bug fixing (eg. you would have to rewrite CreateStruct method yourself as older matlab allowed for createarray(type struct) - not anymore) you may have it working fine.
