Wish Wrap TA-Lib for B4J

[basicall]

TA-Lib : Technical Analysis Library

I hope anyone could wrap this library for B4J.

And, I am willing to donate USD$100 for your precious time.

Closed. Thanks all.

 

[ThRuST]

So what happened, did someone turn it into a library?

 

[basicall]

Yes.

 

[Erel]

It would be nice if you can upload it...

 

[ThRuST]

basicall, please upload the library in your first post as it will be easier to download it, cheers.

Hi Erel,

I could not upload ta.xml file. The xml file is 560kb only but when I upload it I got the error message:

The uploaded file is too large.

 

[ThRuST]

I advice you instead of Erel, because it's Christmas day
You should compress the library files into a zip file, use either ZipWin or WinRAR (with zip format). You can download WinZip Here
Good luck

 

[Erel]

You can send it to [email protected] and I'll upload it. Thank you!

 

[Erel]

The xml file is attached.
