Passing a custom period as parameter in a moving average indicators makes the indicator to return NaN (see sample code). In case the custom period is identical to a built-in period ie ( 1min, 5min) it does return meaningful results.

To reproduce the behavior run the attached code as is and then change the following line:

customTimeframe= Period.createCustomPeriod(Unit.Minute,1);
...works OK

to
customTimeframe= Period.createCustomPeriod(Unit.Minute,2);
..does NOT work

and to
customTimeframe= Period.createCustomPeriod(Unit.Minute,5);
...works OK

Hi,
Strategy won't receive in progress candles for custom periods unless you subscribe to them manually.
Use the following code to subscribe your strategy to custom period in progress candles:

import com.dukascopy.api.listener.IBarFeedListener;
...
public void onStart(IContext context) throws JFException { 
... 
  customTimeframe= Period.createCustomPeriod(Unit.Minute,2);
     
        this.context.subscribeToBarsFeed( 
            Instrument.EURUSD, customTimeframe, OfferSide.BID, new IBarFeedListener() { 
                 public void onBar( 
                    Instrument instrument, 
                    Period period, 
                    OfferSide offerSide, 
                    IBar bar 
                 ) { 
             
                 } 
            } 
        );            
}
