can anybody help me why my strategy doesnt work please.
My strategy is made from strategy which dukascopy prepared for me and i edited.
If it must have different format or something else, can anybody help me with it?

Thanks

There is no code to add currency pairs to trade:

Add following code in onStart method:

 Set<Instrument> instruments = new HashSet<Instrument>();
        instruments.add(Instrument.EURUSD);      
        context.setSubscribedInstruments(instruments, true);

or change your onStart method from below code of onStart Method:

Here is full code for onStart method:

 @Override
    public void onStart(IContext context) throws JFException {
        this.console = context.getConsole();
        this.indicators = context.getIndicators();
        this.history = context.getHistory();
        this.engine = context.getEngine();
        this.context = context;
        
        IChart chart = context.getChart(instrument);
        if (chart != null) {
            chart.addIndicator(indicators.getIndicator("SAR"), new Object[]{acceleration, max});
            chart.addIndicator(indicators.getIndicator("MAMA"), new Object[]{fastLimit, slowLimit});
        }
        Set<Instrument> instruments = new HashSet<Instrument>();
        instruments.add(Instrument.EURUSD);
                        
        context.setSubscribedInstruments(instruments, true);
        
        
        if(useCustomPeriod) {
            selectedPeriod = Period.createCustomPeriod(unit, unitsCount);
        }
        
        feedDescr = configureChartType(context, instrument);
        
        orderMgr = new OrderMgr(maxLongOrders, maxShortOrders, maxTotalOrders);        
        
    }

can you pls help me to edit it to strategy which will work. I am unable to edit it - i dont know where to add thing you wrote.
Thank you very much

Code has been updated to run it in contest account.

If you want to add multiple currencies, for that I have added example also in code and you can take help of that for multiple currencies strategy.

thank you very much, i really appreciate your help

i applied strategy you edited, it is in my contest account but it still doesnt work

Have you tested it on demo account, or have you done historical testing?

I think, strategy is not satisfying buy/sell condition, and will look it tomorrow and then tell you.

Regards,

i was testing it on historical data.
Strategy which i firstly posted normally works on demo acc but in strategy contest it doesnt work.
I am sorry i disturb you but i dont know anything in java
Thanks
