Hello,

I'm updating my strategies on the new Demo2.14.28.1/API 2.6.60.1 so I have no surprise when the Live platform will be online.

I have some troubles with chartobjects drawn from strategies. Please see the following list :


1 - Can't figure out how to create a chartOject with an object Key without using deprecated methods, see exemple :

The following code works, but createRayLine(objectKey, params) is deprecated :

IRayLineChartObject line = chart.getChartObjectFactory().createRayLine(objectKey,
                    lastTick.getTime(), lastTick.getBid() + 0.005,
                    firstPoint.getTime(), lastTick.getBid());
                    chart.addToMainChart(line);

Using the non deprecated method with an objectKey doesn't draw anything :


It seems entering an object key does not work for all chartObjects.

3 - How to lock a chartObject on the chart ? (previously we used addToMainChartUnlocked() to lock or not the object)

It would be nice to have an updated documentation on the chartObject wiki.


Thanks
Best regards

We were not able to reproduce this. We tested with the following strategy:

package charts.test;

import java.awt.Color;
import java.util.UUID;

import com.dukascopy.api.*;
import com.dukascopy.api.drawings.IRayLineChartObject;

public class RayLine implements IStrategy {

    private IChart chart;
    private IHistory history;
    
    @Override
    public void onStart(IContext context) throws JFException {
        this.chart = context.getChart(Instrument.EURUSD);
        this.history = context.getHistory();
        ITick tick = history.getLastTick(Instrument.EURUSD);    

        double price1 = (tick.getAsk() + tick.getBid()) / 2;
        IRayLineChartObject line1 = chart.getChartObjectFactory().createRayLine();
        line1.setPrice(0, price1);
        line1.setTime(0, tick.getTime());
        line1.setPrice(1, price1 - 0.0010);
        //5 bars ahead
        line1.setTime(1, tick.getTime() - chart.getSelectedPeriod().getInterval() * 5);
        line1.setColor(Color.BLUE);
        chart.addToMainChart(line1);
        
        //use the same coordinates, but change the style
        IRayLineChartObject line2 = chart.getChartObjectFactory().createRayLine(UUID.randomUUID().toString(),
                line1.getTime(0), line1.getPrice(0),
                line1.getTime(1), line1.getPrice(1));
        line2.setOpacity(0.2f);
        line2.setColor(Color.RED);
        line2.setLineWidth(10);
        chart.addToMainChart(line2);
        
    }

    @Override
    public void onTick(Instrument instrument, ITick tick) throws JFException {    }

    @Override
    public void onBar(Instrument instrument, Period period, IBar askBar, IBar bidBar) throws JFException {}

    @Override
    public void onMessage(IMessage message) throws JFException {}

    @Override
    public void onAccount(IAccount account) throws JFException {}

    @Override
    public void onStop() throws JFException {}

}

There is no more division in unlocked or locked objects.
Please elaborate on what additional information you would like to find in the JForex wiki? Regarding deprecated methods in object catalog - they have not been replaced, since they are due to be reintroduced but with a more informative signature, e.g.:
instead of:

IRectangleChartObject createRectangle(Object... params)

there will be:

IRectangleChartObject createRectangle(String key, long time1, double price1, long time2, double price2)

Thanks for the reponse.



In Netbeans this is marked as deprecated, isn't it ? : public IRayLineChartObject createRayLine(Object... params)

In the javadoc you see the following syntax to use with a key (I didn't saw this in your exemple). public IRayLineChartObject createRayLine(String key)


And what about my second question about objects not keeping their position after a reboot of JForex (it seems it has been deleted from my message) ? This is for me a more concerning issue. Should I post my screenshot again so you can see ?

Thanks

Yes it is, we included it in the example to show that both methods do the same thing.
This bug has been registered.
This part of your post been moved to
viewtopic.php?f=85&t=46704 since it is related to the desktop platform, not API.

ok thanks
