I've tried this today and it seems to work well... there is one little issue though. Every time the indicator is run I get the following:

ERROR controller.ConnectorController com.dukascopy.api.JFException: Instrument [EUR/USD] not opened

It does, however, give me the correct values.

Just to note, this happens when using the following indicator in a stand-alone strategy.

It happens on whatever currency you're using and it comes from calling the following in onBar

            rsxResultsArray = this.indicators.calculateIndicator(ins, per, new OfferSide[] { OfferSide.BID }, "RSXConnector",
                    new IIndicators.AppliedPrice[] { IIndicators.AppliedPrice.CLOSE }, new Object[] { 3000, 0, 0, true, 500, false }, Filter.NO_FILTER, 500, time, 0);

In general the exception means that the instrument has not been subscribed, see:

Please be advised that MQL4ConnectorIndicator class method signatures are subject to change with upcoming releases, so it is not recommended to use the conversion result for any other than informative purposes.
