Hello support team!

Help me please!

I'm write my backtester using jforex api

In main class? i'm usins setup data period for testing...like in manual...
final SimpleDateFormat dateFormat = new SimpleDateFormat("MM/dd/yyyy HH:mm:ss");
        dateFormat.setTimeZone(TimeZone.getTimeZone("GMT"));
        Date dateFrom = dateFormat.parse("01/01/2015 12:00:00");
        Date dateTo = dateFormat.parse("09/22/2015 00:00:00");
        client.setDataInterval(DataLoadingMethod.ALL_TICKS, dateFrom.getTime(), dateTo.getTime());


in "strategy_play" classes is creating array of classes, that contains price range feeds
        
spectr = new ArrayList<mtfTimeFrame>();
        for (int i=0; i<cfg.numberTF; i++) {
            spectr.add(new mtfTimeFrame(context, cfg, cfg.startTF+cfg.stepTF*i));
        }// End for


constructor feed class create and subscribe to feed
    
//Constructor
    mtfTimeFrame(IContext fcontext, cfgTrading fcfg, int frangeValue) throws JFException {
...
        rangeBarFeedDescriptor = new RangeBarFeedDescriptor(cfg.instrument, PriceRange.valueOf(rangeValue), cfg.offerSide);
        context.subscribeToFeed(rangeBarFeedDescriptor, this);
...
}


feed class contain override method onFeedData...method is empty
@Override
    public void onFeedData(IFeedDescriptor feedDescriptor, ITimedData feedData) {

}


It's result...
