Dukascopy Support Board • View topic - api question : check if instrument is available for trading

mikakun

Hi !

I would like to know if there is a way to know if an instrument is available for online trading before sending an order.

Is that possible with the API or is the only way to wait for a rejected message ?

thanks in advance

NB: orders are not triggered by an onbar or ontick event of the instrument hence why i'm asking

API Support

context.getSubscribedInstruments().contains( Instrument.EURUSD )

mikakun

many thanks for answer

however if you could confirm that i understand correctly, i'd be grateful :

if (context.getSubscribedInstruments().contains( Instrument.XAGUSD )) {
    engine.submitorder(//...
}

so

context.getSubscribedInstruments().contains( Instrument.XAGUSD )

will return false if xagusd is not available for trading at the time of the call of the method and true if it is with almost no chance to see the order being rejected

nb: i obviously took xagusd as example because that instrument if offline many time every day

i've looked in the api & maybe i got what i wanted :

import com.dukascopy.api.IInstrumentStatusMessage;

//...

  public void onMessage(IInstrumentStatusMessage message) throws JFException {

      if (message.getType().equals(IMessage.Type.INSTRUMENT_STATUS) && instruments.contains(message.getInstrument())) {

                     
              console.getOut().println(message.getInstrument()+" tradabie : "+message.isTradable());

      }
    }

haven't received that status message yet to confirm I got it right (couldn't find any example on how to use that interface on the web).

thanks for help if i'm missing something

If(instrument.equals("USDCAD") && period.equals("TEN_MINS")) {
...
}

But you must "Subscribe" first (getting "pointers" to instruments).

No of course i'm suscribed to all instruments i need.

what i'm trying to do is to know whether an instrument is tradable on an onbar or ontick event of another instrument.

i didn't get no message from the IInstrumentStatusMessage method...

Please help !
