Can indicator code get info for all instruments displayed on chart?

[kdoren]

For a multi-instrument indicator, is there a way for the indicator code to read the symbol and other info for all instruments displayed on the chart?

Right now I need to enter the symbol for the second instrument as a parameter for the indicator. But in many cases, the second instrument will already be displayed on the chart. If the indicator code could read the information for all of the instruments on the chart, it could make it easier to set up multi-instrument indicators.

Unfortunately this is not supported.

Actually I was just thinking the other day too that this would be a nice feature.

Then I was thinking there must be some way to get this info and found this (e.g. use in Initialize):

Of course this is probably highly unsupported.

terenyi, Thanks for the tip. The following code seems to work nicely in the Properties section; if "Symbol2" is blank, when you apply the indicator it defaults to the first symbol on the chart that isn't the indicator's primary symbol:

[Description("Symbol 2\nDefault = Secondary chart instrument")]
[GridCategory("Parameters")]
// Force this parameter to be displayed second
[Gui.Design.DisplayName ("\t\tSymbol 2")]
public string Symbol2
{
     get 
     { 
          if ((symbol2 == "") && (ChartControl != null) && (Instruments != null)) 
               for(int i=0; i<ChartControl.BarsArray.Length; i++)
                    if (ChartControl.BarsArray[i].Instrument.FullName != Instruments[0].FullName)
                    {
                         symbol2 = ChartControl.BarsArray[i].Instrument.FullName;
                         break;
                    }
          return symbol2; 
     }
     set { symbol2 = value.ToUpper(); }
}
