Hi,

I would like to setup alerts on leverage change

use of leverage

any change "use of leverage" raises alert

Consider doing something like this:

package jforex.account;

import javax.swing.JFrame;
import javax.swing.JOptionPane;

import com.dukascopy.api.*;

public class UseOfLeverageAlerter implements IStrategy {

    double lastUseOfLeverage;
    private IAccount account;
    private IConsole console;
    
    @Configurable("Use dialog")
    public boolean showDialog = true;
    
    @Override
    public void onStart(IContext context) throws JFException {
        account = context.getAccount();
        console = context.getConsole();
        lastUseOfLeverage = context.getAccount().getUseOfLeverage();

    }

    @Override
    public void onTick(Instrument instrument, ITick tick) throws JFException {
        double currentUseOfLeverage = account.getUseOfLeverage();
        if(Double.compare(currentUseOfLeverage, lastUseOfLeverage) != 0){
            String infoMessage = String.format("Leverage changed from %s to %s",
                    lastUseOfLeverage, currentUseOfLeverage);
            console.getOut().println(infoMessage);
            if(showDialog){
                JOptionPane.showMessageDialog(new JFrame("dialog"),infoMessage);
            }
            lastUseOfLeverage = currentUseOfLeverage;
        }
    }

    @Override
    public void onBar(Instrument instrument, Period period, IBar askBar, IBar bidBar) throws JFException {}

    @Override
    public void onMessage(IMessage message) throws JFException {}

    @Override
    public void onAccount(IAccount account) throws JFException {}

    @Override
    public void onStop() throws JFException {}

}

when changing the "Use of Leverage", can be told that some alarm,song,melodies?

can be replaced by INFO messages, the audible alarm ?

See:
https://www.dukascopy.com/wiki/#Extending_User_Interface/Bottom_tab_with_a_price_alerter

Can you send me to attach. the finished program, simply, use of leverage> 0, the alarm is active, that is all

just change the condition:

if(Double.compare(currentUseOfLeverage, lastUseOfLeverage) != 0){

to

if(Double.compare(currentUseOfLeverage, 0) == 1 && Double.compare(lastUseOfLeverage, 0) == 0){

See more on compare:
https://docs.oracle.com/javase/1.4.2/docs/api/java/util/Comparator.html#compare(java.lang.Object,%20java.lang.Object)

I tried to add an alarm sound start in this program, but to exclude and expel this message:



21:19:21 Strategy "UseOfLeverageAlerter" is stopped at 2012-05-06 21:19:21.569 GMT on the local computer with parameters "Alarm file"=[D:\dukas\wav\feelgood.wav], "Use dialog"=[true]

please help me, what did I go wrong?

You have to include this annotation before the class name
