Dear support,
it seems there is a bug in TickFeedListener and maybe in all other FeedListeners.
Please consider the following simple Strategie to reproduce the problem. The listeneres received a different number of ticks, especially the first listener "Listener 1" reveived ticks only sometimes!
package jforex;
import com.dukascopy.api.*;
import com.dukascopy.api.feed.ITickFeedListener;
import java.util.HashSet;
import java.util.Set;

private IContext context;
private IIndicators indicators;
private IUserInterface userInterface;
@Override
public void onStart(IContext context) throws JFException {
this.context = context;

}
}
}
Please investigate and let us know the result.
Thank you and best regards,
