i created ma indicator with period 1 and offer side=bid and compared to ticks



Code at onStart():

        ticks = history.getTicks(instrument, begin.getMillis(), end.getMillis());
        double[] zz = indicators.ma(instrument,Period.TICK, OfferSide.ASK, IIndicators.AppliedPrice.CLOSE, 1, MaType.SMA, begin.getMillis(), end.getMillis());
        System.out.println("TICKS SIZE: "+ticks.size()+", zz.len: "+zz.length);
 
        /**
         * CREATING CHART.
         */
        Chart c = new Chart("NN out visualizer");
        c.pack();
        RefineryUtilities.centerFrameOnScreen(c);
        c.setVisible(true);
 
        /**
         * DRAWING INDICATOR.
         */
        for(int i=0; i<ticks.size(); i++) {
            c.add(new SimpleDateFormat("SSS ss mm HH dd MM yyyy").format(ticks.get(i).getTime()), zz[i], ticks.get(i).getBid());
            //add to graph: datetime, indicator[i] and bid[i]
        }

So, how to get indicator data correctly??????

This is normal. Unlike candles ticks have different frequency in different time intervals. If raw tick data were used some indicators may get skewed in favor of regions with higher or lower tick frequency. Therefore, ticks are normalized so that there is around 1 tick per second.
