Hello,

I am new to jforex platform, I have knowledge with metatrader and mq4 coding


How can I create a simple strategy for buying all USD pairs and set a total loss in account currency?

for example:

AUDUSD sell
NZDUSD sell
EURUSD sell
GBPUSD sell
USDCHF buy
USDCAD buy
USDJPY buy

Start here:

See:

and

thanks API support,

I tried the following code for buying all USD pairs but it gives me errors when compiling.

This is the complete strategy:

package jforex;

import java.util.*;

import com.dukascopy.api.*;

public class USDbuy implements IStrategy {
    private IEngine engine;
    private IConsole console;
    private IHistory history;
    private IContext context;
    private IIndicators indicators;
    private IUserInterface userInterface;
        
    
    
    @Configurable("Amount")
    public double amount = 0.002;
    @Configurable("Price")
    public double price = 0;
    @Configurable("Slippage")
    public double slippage = 2;
   
    
    private int counter = 0;
    
    public void onStart(IContext context) throws JFException {
        this.engine = context.getEngine();
        this.console = context.getConsole();
        this.history = context.getHistory();
        this.context = context;
        this.indicators = context.getIndicators();
        this.userInterface = context.getUserInterface();
        
        
        Set<Instrument> instruments = new HashSet<Instrument>();
        instruments.add(Instrument.AUDUSD);
        instruments.add(Instrument.EURUSD);
        instruments.add(Instrument.GBPUSD);
        instruments.add(Instrument.NZDUSD);
        instruments.add(Instrument.USDCAD);
        instruments.add(Instrument.USDCHF);
        instruments.add(Instrument.USDJPY);

        context.setSubscribedInstruments(instruments);
        try {
            Thread.sleep(1000);
        } catch (InterruptedException ex) {
        }
        
        engine.submitOrder("AUDUSD", Instrument.AUDUSD, OrderCommand.SELL, amount, price, slippage);
        engine.submitOrder("EURUSD", Instrument.EURUSD, OrderCommand.SELL, amount, price, slippage);
        engine.submitOrder("GBPUSD", Instrument.GBPUSD, OrderCommand.SELL, amount, price, slippage);
        engine.submitOrder("NZDUSD", Instrument.NZDUSD, OrderCommand.SELL, amount, price, slippage);
        engine.submitOrder("USDCAD", Instrument.USDCAD, OrderCommand.BUY, amount, price, slippage);
        engine.submitOrder("USDCHF", Instrument.USDCHF, OrderCommand.BUY, amount, price, slippage);
        engine.submitOrder("USDJPY", Instrument.USDJPY, OrderCommand.BUY, amount, price, slippage);
        
        context.stop();
    }
    
    
    private String getLabel(Instrument instr) {
        String label = instr.name();
        label = label + (counter++);
        label = label.toUpperCase();
        return label;
    }

    public void onAccount(IAccount account) throws JFException {
    }

    public void onMessage(IMessage message) throws JFException {
    }

    public void onStop() throws JFException {
    }

    public void onTick(Instrument instrument, ITick tick) throws JFException {
    }
    
    public void onBar(Instrument instrument, Period period, IBar askBar, IBar bidBar) throws JFException {
    }
}

the problem seems to be in the following piece of code:

        engine.submitOrder("AUDUSD", Instrument.AUDUSD, OrderCommand.SELL, amount, price, slippage);
        engine.submitOrder("EURUSD", Instrument.EURUSD, OrderCommand.SELL, amount, price, slippage);
        engine.submitOrder("GBPUSD", Instrument.GBPUSD, OrderCommand.SELL, amount, price, slippage);
        engine.submitOrder("NZDUSD", Instrument.NZDUSD, OrderCommand.SELL, amount, price, slippage);
        engine.submitOrder("USDCAD", Instrument.USDCAD, OrderCommand.BUY, amount, price, slippage);
        engine.submitOrder("USDCHF", Instrument.USDCHF, OrderCommand.BUY, amount, price, slippage);
        engine.submitOrder("USDJPY", Instrument.USDJPY, OrderCommand.BUY, amount, price, slippage);

You can avoid compile-time errors by using an IDE like Eclipse or NetBeans.
