Hello,

I have troubles getting the same values as the chart for the SAR
indicator when using the universal method with feed descriptors.

           // This works :
            print("SAR : "+ indicators.sar(Instrument.EURUSD, Period.ONE_MIN, OfferSide.BID, 0.02, 0.2, 0));
            
            // This doesn't
            FeedDescriptor feed = new FeedDescriptor();
            feed.setPeriod(Period.ONE_MIN);
            feed.setInstrument(Instrument.EURUSD);
            feed.setDataType(DataType.TIME_PERIOD_AGGREGATION);
            feed.setOfferSide(OfferSide.BID);
            feed.setFilter(Filter.NO_FILTER);
            
            Object[] output = indicators.calculateIndicator(feed,new OfferSide[]{feed.getOfferSide()}, "SAR", new AppliedPrice[] { null }, new Object[] { 0.02, 0.2 }, 0);
            print("Sar feed : [0] " + output[0]);
            output = indicators.calculateIndicator(feed,new OfferSide[]{feed.getOfferSide()}, "SAR", null, new Object[] { 0.02, 0.2 }, 0);
            print("Sar feed : [1] " + output[0]);
            output = indicators.calculateIndicator(feed,new OfferSide[]{feed.getOfferSide()}, "SAR", new AppliedPrice[] { AppliedPrice.CLOSE }, new Object[] { 0.02, 0.2 }, 0);
            print("Sar feed : [2] " + output[0]);

I'm attaching a strategy with the different things I tried. Maybe you
could help me figure out what to do .. or is it a bug ?

Thanks and regards

Have you taken a look at the following?

Also try:
https://www.dukascopy.com/wiki/#Calculat ... _on_a_feed

I went through the documentation before posting and used some of it to try to achieve my goal without success.
I've attached the source code to reproduce my issue : add the SAR indicator to a EURUSD , 1Min, Bid chart, the non universal way works, none of the multiple universal attempts are actually the same

Maybe someone can test and confirm the issue and/or submit the correct way to do it if they get it to work.
