Post subject:  drawing indicator twice on one chart problem
I've tried add to one chart two the same indicators drawing object (examples from https://www.dukascopy.com/wiki/en/development/indicator-api/examples/indicator-draws-chart-objects) on chart with diferent optional inpus. Unfortunatelly only one has been drawn correctly (with period 20), the second one (period 10) is not visible.

There is something what sholud bee added to code to fix it?

Thank you so much in advance,
Lukas

I have a similar, if not the same problem. My indicator does not draw on the chart, but I call it twice from the strategy using different optional inputs. As you can see from the code sample below, I have different IIndicator objects (track2s and track2b) for a custom indicator Track2. Track2 accepts 1 optional input. In code below either 3.5 or 6.5. Despite all this, when I display the first output index from strategy, the values are the same! BUT, if I print from inside the custom indicator, each indicator value is different (correct) because OptionalInputs are different.

This problem is sooooo annoying!

           Object[] rngResult = indicators.calculateIndicator(
                this.rangeDescriptor,
                new OfferSide[] { OfferSide.BID }, 
                track2s.getIndicatorInfo().getName(),
                new IIndicators.AppliedPrice[] {IIndicators.AppliedPrice.CLOSE}, 
                new Object[]{ 3.5 },
                0
            );
            loadArrays( rngResult, 0);
            
            Object[] rngResult2 = indicators.calculateIndicator(
                this.rangeDescriptor,
                new OfferSide[] { OfferSide.BID }, 
                track2b.getIndicatorInfo().getName(),
                new IIndicators.AppliedPrice[] {IIndicators.AppliedPrice.CLOSE}, 
                new Object[]{ 6.5 },
                0
            );
            loadArrays( rngResult2, 1);
