ChartControl visibility / accessibility

[Philippe56140]

Hi There

I have an indicator which is calculating data from another indicator.
This other indicator may be one of those present on the chart.

To get a list of theses available indicators, I need to write a TypeConverter listing all active indicator.

However, I'm facing a problem due to the fact that ChartControl is not accessible at this moment:

namespace NinjaTrader.NinjaScript.Indicators
{

    public class myIndicator : Indicator
    {
        protected override void OnStateChange()
        {
            //...
​
        }

        protected override void OnBarUpdate()
        {
            //...
        }

        #region Properties

        [TypeConverter(typeof(NinjaTrader.NinjaScript.IndicatorListConverter))]
        public string IndicatorName  
         { get; set; }    

        #endregion
    }

    public class IndicatorListConverter : StringConverter
    {
        public override StandardValuesCollection GetStandardValues(ITypeDescriptorContext context)
        {
            List<string> values = new List<string>();
            if (ChartControl != null && ChartControl.Indicators != null)
                lock (ChartControl.Indicators)
                    values = ChartControl.Indicators.Select(i => i.Name).ToList();

            return new StandardValuesCollection(values);
        }
    ...
    }    
}

Error is: ChartControl is used as a type but is used as a variable

Is there any function to get a reference on the actual ChartControl ?

Hello Philippe56140,

Thanks for your patience.

There is no supported way to list the chart's indicators, however, this could be accomplished with unsupported code.

Please see the example scripts shared by my colleague Chelsea on the forum threads linked below for an example of how this could be done through unsupported code.
