Hi please help the wiki is not very explanatory nor does it provides any example.

https://www.dukascopy.com/wiki/#Instrument_tradability

i've tried

  
import com.dukascopy.api.IInstrumentStatusMessage;
//...
public void onStart(IContext context) throws JFException {

        context.setSubscribedInstruments(instruments);

    }


public void onInstrumentStatusMessage(IInstrumentStatusMessage message) throws JFException {

      if (instruments.contains(message.getInstrument())) {


       console.getOut().println("onInstrumentStatusMessage(IInstrumentStatusMessage  -- ---"+message.getInstrument()+" tradable "+message.isTradable());

       }
    }
  public void onMessage(IInstrumentStatusMessage message) throws JFException {

       if (instruments.contains(message.getInstrument())) {


         console.getOut().println("onMessage(IInstrumentStatusMessage  -- ---"+message.getInstrument()+" tradable "+message.isTradable());
       }

 

algo doesn't seem to receive any status message

please api support explain me how this IInstrumentStatusMessage interface works as it's advertised to in the wiki. i've been losing hours on this already...

in case anyone is interested here is a work around until the support deign to explain how to use .isTradable()

 
public Instrument instrument;
public boolean instrumentIsTradable;

public void onMessage(IMessage message) throws JFException {

      if (message.getType().equals(IMessage.Type.INSTRUMENT_STATUS)) {
          String m = message.toString();
          if (m.contains(instrument.toString())) instrumentIsTradable = m.contains("true") ? true : false;
}

In manual, there is tradeability by hours checking, but you must know exact hours.

Instrument trading hours usually don't change. Historical trading hours can be seen on chart by disabling flats filtering.
That can be done from settings by selecting Tools > Preferences > Chart Flats Filter is disabled.

got an answer from support,

here is how to use IInstrumentStatusMessage.isTradable() :

    
public void onMessage(IMessage message) throws JFException {
        if(message instanceof IInstrumentStatusMessage) {
            IInstrumentStatusMessage instrumentMessage = (IInstrumentStatusMessage) message;
            console.getOut().println("Instrument: "+ instrumentMessage.getInstrument()+ ", isTradable: "+ instrumentMessage.isTradable());            
        }
    }

thanks to them
