Hello, please help me. I started develop new strategy, and cant get values of indicator...

Open new chart:

        this.feedDescriptor = new FeedDescriptor();
        
        this.feedDescriptor.setDataType(DataType.TICKS);
        this.feedDescriptor.setInstrument(this.instrument_current);
        this.feedDescriptor.setPeriod(Period.TICK);
        this.feedDescriptor.setOfferSide(OfferSide.BID);
        this.feedDescriptor.setFilter(Filter.WEEKENDS); 
        
        this.chart = context.openChart(this.feedDescriptor);

Add indicator on chart:

        BBANDS = indicators.getIndicator("BBANDS");
        
        this.chart.add(
            BBANDS, 
            new Object[]{80, 2.0, 2.0, MaType.SMMA.ordinal()},
            new Color[]{Color.yellow, Color.orange, Color.yellow},
            new OutputParameterInfo.DrawingStyle[]{OutputParameterInfo.DrawingStyle.LINE, OutputParameterInfo.DrawingStyle.DASH_LINE, OutputParameterInfo.DrawingStyle.LINE},
            null);

And how can i get values of this indicator on TICK chart ???

Last chart outputs can be obtained through IChart.getLastCalculatedIndicatorOutputs().
