Dear Support,

I converted an mq4 indicator, but when I try to use it, I got a warning and an error.
The warning:


The error:



I attach the original mq4 indicator, and the converted jfx file as well.

As the generated java source is not available, I cannot see what causes the exception. I think it is not related to the warning about the webpage download, but I am not sure.


Could you give me some hints, how to go on?

Thanks in advance!

Dear Support,

I`ve tested yesterday this mq4 indicator, and there is no more nullpointer exception.


However the converted indicator still not working.
I was able to get a bit further, and locate a problem with this line:

iResult = InternetReadFile(hInternet, sBuffer, Buffer_LEN, lReturn);

In the mq4 version (and in metatrader4), the above line successfully update the sBuffer with the given webpage (or at least the first Buffer_LEN characters).
In the converted .jfx version this line leaves the sBuffer string empty. Could you explain why?

This MT4 indicator uses a dll library for connecting to a web server and downloading a xml file. JForex cannot work with external dll libraries like MetaTrader.
It is reasonable to re-write such indicator in Java instead of converting.

Thanks for the reply.

Would that be an option, just to avoid future frustration, to detect during conversion if an mq4 indicator contains such thing (external dll calls)? If it is, just stop the process with a friendly message, saying this conversion is not possible.
