How to add Moving Average as Dataseries?

[ttodua]

I a building multi-dropdown chooseable (enum) MA indicators. code looks like

enum MaTypes{
	DEMA,
	EMA,
	HMA 
	.....
}

private DataSeries ma_value;

Initialize () {
	ma_value =  
		( maType == MovAvgType.DEMA	? DEMA	(Close,ma_Length) :
		( maType == MovAvgType.EMA	? EMA	(Close,ma_Length) :
		( maType == MovAvgType.HMA	? HMA	(Close,ma_Length) :
		 ....  
		 
			
	Add(ma_value);
	ma_value.Plots[0].Pen.Color = ma_1_Color;
}

OnBarUpdate(){
......
	double xyz= ma_value[0];
......
}

however, something here seems incorrect, because as i know, ma_value should be set not to DataSeries, but the exact type i.e. SMA ma_value, EMA ma_value or etc..

however, setting up all those private variables individually kills me, because in strategy i am making multiple dropdowns for 4 choosable MA-s, and I want the code to be compact like above...

I have found this topic - http://ninjatrader.com/support/forum...ead.php?t=3420, but as i say, i dont want that way:

private DEMA dema_val;
private EMA ema_val;
.............

Initialize () {
...
	if( maType == MovAvgType.DEMA	)
		dema_val	= DEMA(Close,ma_Length);
	}
	else if( maType == MovAvgType.DEMA	)
		ema_val		= EMA(Close,ma_Length);
	}
...
}



OnBarUpdate(){
......
	if( maType == MovAvgType.DEMA	)
		double xyz = dema_val[0];
	}
	else if( maType == MovAvgType.DEMA	)
		double xyz = ema_val[0];
	}
......
}

this will be very annoying... I wish i could achieve like i've written in the top .. What C# thing i have to do , i.e. https://stackoverflow.com/questions/...ord-in-the-clr ?

Hello selnomeria,

An example of this can be found in the reference samples.

so, SMA type can hold other as reference, without throwing type mismatch errors, right? Wow, that's what i wanted!


Do you know what I am interested in?
How support team, in many cases, is unable to offer solution, while users like konagam, know solutions...

Excellent! and the Enums are declared nicely too!

Well, more like I am using the parent class, Indicator, to hold the derived types.

The critique is only somewhat valid, because we also have to remember that NT Support are employees, and have to act within the support parameters that the company sets. We, on the other hand are geeks, who can go outside those boundaries, to help other geeks.

Well, I really hate pollution of the Global namespace. Many years ago, when I was a Product Engineer for a huuuuuge computer company, I routinely rejected any code that polluted the Global namespace, unless it could really be justified, in which case the declaration was moved into the Global namespace definition file, not a class file.
