Plotting Indicator On Chart With Variables

[naydee]

Hello. I've been trying to figure this out for a few days and no can do. Im trying to simply add an opening range indicator to the chart in my strategy but don't want the time parameters to be static, instead I'd like to select them in the strategy analyzer so I can optmize/try different time's etc.

The issue is, getting the ADD function to recognize my line of code which includes variables. This is what the normal static line would look like without variables
Add(BzvOpeningRange4("0300", "0400", "1400"));

Im looking to replace the three time slots with variables and created the following code:

	#region variables
		private string 	ORind 				= null;		//String to hold the full code for the Opening Range Indicator
		private int		orstarth			= 300;		// Opening Range Start Hour
		private int		orstartm			= 30;		// Opening Range Start Minutes
		private int		orendh				= 400;		// Opening Range End Hour
		private int		orendm				= 0;		// Opening Range End Minutes
		private int		orstoph				= 1300;		// Opening Range Stop Hour
		private int		orstopm				= 0;		// Opening Range Stop Minutes
		
		private int 	orstart 			= 0;		// Opening Range Start Time. Hour and minutes combined
		private int 	orend				= 0;		// Opening Range End Time. Hour And Minutes Combined
		private int 	orstop 				= 0;		// Opening Range Stop Time. Hour And Minutes Combined
	#endregion

protected override void Initialize()
		{
			orstart = orstarth+orstartm; 	//Combines the Hour and minutes
			orend = orendh+orendm;			//Combines the Hour and minutes
			orstop = orstoph+orstopm;		//Combines the Hour and minutes
			ORind = "BzvOpeningRange4(\"0"+orstart+"\", \"0"+orend+"\", \""+orstop+"\")"; 	 //Combines all the above into a string
			PrintWithTimeStamp(ORind);		//Prints Output just for visual confirmation
			Add(ORind);						//Actual line which ADDs the indicator
		}

THe print output shows exactly what I should have which is
BzvOpeningRange4("0300", "0400", "1400")
but when compiling I get the following error messages
"The best overloaded method match for 'NinjaTrader.Strategy.StrategyBase.Add(NinjaTrader .Indicator.IndicatorBase)' has some invalid arguments"
"Strategy\OrbNay1g.cs Argument '1': cannot convert from 'string' to 'NinjaTrader.Indicator.IndicatorBase' CS1503 - click for info 977 8"

Any help would be appreciated

naydee, would this compile for you then as alternative?

Add(BzvOpeningRange4(orstart, orend, orstop);

Your present version will not compile as it expects an indicator as input and not a string.

Thats what I had originally tried and it didn't work.. As I was waiting for your response I tried the following and it did indeed work
Add(BzvOpeningRange4("0"+orstart+"", "0"+orend+"", ""+orstop+""));

Seems the quotes are needed for the indicator, without them it won't compile. Its now loading perfectly, question.. When I refer to this indcator within my strategy "onbarupdate" should I reference it just as above with the dual double quotes or is there a more elegant way? Im just making some of this stuff up through trial and error and reading the forums

Great to hear.

You could assign as well to a variable like -

private BzvOpeningRange4 ind; // in your variables section

ind = BzvOpeningRange4("0"+orstart+"", "0"+orend+"", ""+orstop+"");

And then call ind[0] for example in OnBarUpdate() for the current value...

Oh great, I didn't know you could do that. I will give it a shot. Thanks bud
