Can we program sound alarms on level prices or indicators.
Thank you for your answer.

Try this one:

   import java.io.*;
   import javax.sound.sampled.*;

   ...
   playSound("C:/temp/testsound.wav", 10);
   ...

   private void playSound(String _sWavFile, int _nRepeats)
   {
      try
      {
         AudioInputStream audioInputStream = AudioSystem.getAudioInputStream(new File(_sWavFile));
         AudioFormat af = audioInputStream.getFormat();
         int nSize = (int) (af.getFrameSize() * audioInputStream.getFrameLength());
         byte[] audio = new byte[nSize];
         DataLine.Info info = new DataLine.Info(Clip.class, af, nSize);
         audioInputStream.read(audio, 0, nSize);

         for(int i=0; i < _nRepeats; i++)
         {
            Clip clip = (Clip)AudioSystem.getLine(info);
            clip.open(af, audio, 0, nSize);
            clip.start();
         }
      }
      catch(Exception e)
      {
         console.getOut().println(e.getMessage());
      }     
   }

It works very well, thank you RoadRunner.

If you keep sound files in "My Strategies/files" you can avoid to use full access annotation and get rid of warning message appearing on every start.

Hello,

Sorry for my poor English and programming skills............... :oops:

I'm interested in the audio alarm indicator, so it would be kind of you if anyone could explain step by step the process of compilling the right way java files ?

I try to compil it but get syntax error : this is below the report message.

Thanks for all

Happy and fun trading

the few suggestions at the top there are pseudocode, you need to include the call to playSound() in a method;
you should really learn the java language reasonably, to write a strategy - even a minimal one
see https://java.sun.com/docs/books/tutorial/index.html

Hello to everyone, I'm opening again this post because I'm new of Jforex and I wish have some allarm when my order start, or it take the S.L. or T.P.
How I can do to do this?
I tried to read and use the code that you propose, but I don't know were I've to put in my windows, and same on my Mac.
Could I please know were I've to put those code?
Thank you for you answer

Hi Nuvolare,

you just have to paste the code into your strategy code and then call playSound(<filepath to wav>, <repeat times>); in your code where you want the audio to play (e.g. after submitting your order). Other than adding

import java.io.*;
import javax.sound.sampled.*;

no other external references are needed.

If your wav-files are located outside your strategy file path, then you have to add @RequiresFullAccess in your strategy class definition to allow your strategy to access the file path where you locate your wav-files.

Example for a strategy file Test.java with full access to your pc's file structure:

@RequiresFullAccess public class Test implements IStrategy
{
...
}

I hope this helps.
Best, RR.

Ok, so I pasted the code in the strategy, and in the left down corner there are a small windows and there in "Strategy" there are the code calls MySoundNotification.
Now when I submit an order what I've to do?
Sorry but I don't know much about the code.
Thank you

Could you please post your code?

Hi nuvolare,

sorry, I missed out your post...

If you haven't already solved the problem, first thing you have to do is to include the @RequiresFullAccess annotation in your class definition.
Without that annotation java will have no access to files outside the strategy path such as your wav file.

change

public class MySoundNotificationStrategy implements IStrategy {
...

to

@RequiresFullAccesspublic class MySoundNotificationStrategy implements IStrategy {
...

I didn't try your code, but at first sight everything else looks good.

Best, RR.

Sorry nuvolare,

there was a misspelling in the code snippet in my previous posting.

There of course should be a blank between the annotation and 'public':

RequiresFullAccess public class MySoundNotificationStrategy implements IStrategy {
...
