Is there a way to get properties of secondary instrument?

[kdoren]

In a multi-instrument indicator/strategy, I can pass the symbol of the secondary instrument as a parameter, then Add() it.

Is there a way to look up properties such as PointValue, etc, that can be looked up for the MasterInstrument? If not there should be...

Right now you can't access .Instrument property in Initialize(). This was something people complained about. We will change this with next update so you e.g. could do something like .Instrument.MasterInstrument.PointValue in Initialize().

I'm asking about a secondary instrument. Even in OnBarUpdate, can I look up the PointValue or other properties of a secondary instrument? i.e. if my indicator has a parameter "Symbol2" which is the symbol for a secondary instrument, and I Add() Symbol2 in Initialize(), is there any way to look up the PointValue of Symbol2, even in OnBarUpdate?

Thanks

Sure, in OnBarUpdate() you just could go with .Instruments[1].MasterInstrument... Same like with multi-series strategies in NT6.5

The same with NT 6.5 multi-instrument strategy :

This is NT7 beta forum but the issue is relevant for NT 6.5 either.

What I wanted to do is to add secondary instruments having the same PeriodType and Period value as the master instrument.

From my own experiments and from your answer to Kevin I understand it's impossible , because we can know master instrument properties only in OnBarUpdate and of course it is too late to Add() new instruments there.

My workaround to this problem is to add all instruments including replicated master instrument, specifying PeriodType and its period for all instruments participating in my strategy, e.g. add EUR , JPY , EURJPY , everyone of them is Range 20 , despite my master instrument, EURJPY , Range 20 already exists.
It works , but it wastes precious resources . May be , in NT7 with its supposedly better memory management it's not an issue at all.

It's not hard, see code below. I made the property getter a bit more complicated so it will default to a secondary instrument displayed on the chart.

in Variables:

private string symbol2 = "";


in Initialize:

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


in Properties:

[Description("Symbol 2; 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(); }
}

Thank you, it's not exactly what I'm looking for, but it helped me.
I used just:

            if ( ChartControl != null)
                {
                sPr = ChartControl.BarsArray[0].ToString() ; 
                }

Where sPr includes all needed information about the master instrument, it only needs to be parsed.
