Hello,

Could you show some examples on how to work with fibo retracements objects real time on tick? (object: IFiboRetracementChartObject)
I would like to see it working, as the levels are not shown on the chart if the object it's coded to show automatically from the strategy, updating on each new tick for example.

Thank you.

See JForex wiki (Drawing type FIBO):
https://www.dukascopy.com/wiki/index.php ... wing_types:
You can then use similar code to redraw the fibo lines on every onTick. Note that there are custom fibo levels used in the following strategy example:

package charts.test;

import java.awt.Color;
import java.util.Date;

import com.dukascopy.api.*;
import com.dukascopy.api.drawings.IChartObjectFactory;
import com.dukascopy.api.drawings.IFiboRetracementChartObject;

public class FiboRetracementsCustom implements IStrategy {
   private IChart chart;

   public Instrument instrument = Instrument.EURUSD;
   public Period selectedPeriod = Period.TEN_SECS;

   private IFiboRetracementChartObject fiboObj;

   public void onStart(IContext context) throws JFException {
      this.chart = context.getChart(instrument);
   }

   public void onAccount(IAccount account) throws JFException {
   }

   public void onMessage(IMessage message) throws JFException {
   }

   public void onStop() throws JFException {
      if(fiboObj != null)
         chart.remove(fiboObj);
   }

   public void onTick(Instrument instrument, ITick tick) throws JFException {
      if (!instrument.equals(instrument))
         return;
      drawFiboWithLevels(tick.getBid(), tick.getBid() + 0.0010);
   }

   public void onBar(Instrument instrument, Period period, IBar askBar, IBar bidBar) throws JFException {
      // if (!instrument.equals(instrument) || !period.equals(selectedPeriod)) return;
      // drawFiboWithLevels(bidBar.getClose(), bidBar.getClose() + 0.0010);
   }

   private void drawFiboWithLevels(double priceMin, double priceMax) {

      if (chart == null)
         return;

      IChartObjectFactory factory = chart.getChartObjectFactory();

      // there is max 1 fibo retracement at a time
      if (fiboObj == null) {
         fiboObj = factory.createFiboRetracement();
      }

      fiboObj.setPrice(0, priceMin);
      fiboObj.setTime(0, (new Date()).getTime() - 5000);
      fiboObj.setPrice(1, priceMax);
      fiboObj.setTime(1, (new Date()).getTime());

        // remove the standard levels
        for (int i = fiboObj.getLevelsCount() - 1; i >= 0 ; i--) {
            fiboObj.removeLevel(i);
        }
        
      // add customized levels
      Color color = Color.BLACK;
      fiboObj.addLevel("level 1", 0.10, color);
      fiboObj.addLevel("level 2", 0.30, color);
      fiboObj.addLevel("level 3", 0.50, color);
      fiboObj.addLevel("level 4", 0.70, color);
      fiboObj.addLevel("level 5", 0.90, color);

      chart.addToMainChart(fiboObj);
      chart.repaint();
   }

}
