Adding indicator on a secondary data series

[elirion]

Hi experts,

Currently, I am using a range chart + AroonOscillator indicator.

My code goes like this:

myAroonOscillator = AroonOscillator(25);
myAroonOscillator.Plots[0].Brush = Brushes.DarkGreen;
myAroonOscillator.Plots[0].PlotStyle = PlotStyle.Bar;
myAroonOscillator.Plots[0].AutoWidth = true;
AddChartIndicator(myAroonOscillator);​

I wanted to use the oscillator on a 5min timeframe instead so I added this

else if (State == State.Configure)
{
AddDataSeries(Data.BarsPeriodType.Minute, 5);
}

and modified the indicator code to

myAroonOscillator = AroonOscillator(BarsArray[1],25);
myAroonOscillator.Plots[0].Brush = Brushes.DarkGreen;
myAroonOscillator.Plots[0].PlotStyle = PlotStyle.Bar;
myAroonOscillator.Plots[0].AutoWidth = true;
AddChartIndicator(myAroonOscillator);​

Now my indicator part of the chart is just blank. I can get a value off the variable myAroonOscillator though. So I assume I am missing something and resulting in a display issue. Any advice ?

Hello elirion,

Thank you for your post.

From the Help Guide page on AddChartIndicator:

An indicator being added via AddChartIndicator() cannot use any additional data series hosted by the calling strategy, but can only use the strategy's primary data series.

If you wish to use a different data series for the indicator's input, you can add the series in the indicator itself and explicitly reference it in the indicator code (please make sure though the hosting strategy has the same AddDataSeries() call included as well)
