Multi Instrument Questions

[tazatek]

I'm looking for information on the capabilities of multi-instrument indicators...

Is it yet possible to have a price chart in panel 1 and a price/indicator in panel 2 and write an indicator in panel 3 that references panel 1 & 2 Price/Indicator data - programatically?

Or is the only way to get 2 instruments into an indicator through an input parameter that gets the instrument name and sends it into an indicator?


Thanks

I do it by having a parameter ("Symbol2") which can be set by the user, but which defaults to the second instrument on the chart.

If you want to reference an indicator on the chart instead of an instrument, I've never done that; it might be possible but it would probably be a pain to figure out how to do it.

// in the Variables region:

private string symbol2 = "";

// in Initialize():

Add(Symbol2, BarsPeriod.Id, BarsPeriod.Value);

// in the Properties region:

[Description("Secondary Symbol; i.e. SPY or ES 03-10\nDefault = Secondary chart instrument")]
[GridCategory("Parameters")]
// Force this parameter to be displayed first
[Gui.Design.DisplayName ("\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(); }
}

Thanks!

That's what I needed.


Being able to access an indicator from another panel would be nice, but a symbol will do for now.

Thanks again.
