Bar Score Over N Bars

[koganam]

So I think I need to work on this step wise.

1st: Can someone please confirm that if I place this code:

[Browsable(false)]
[XmlIgnore()]
public double Seriessum
{
get { return seriessum; }
}

In the Properties section of the IndicatorSource code, that other indicators will be able to access the IndicatorSource's Seriessum values?

Before I get into adding an indicator to another indicator, I first want to make sure that I have properly revealed the Seriessum values for use.

Thanks,

We need to be sure of what you want to do.

Are you sure that you want to expose a double, rather than a DataSeries. The code that you have posted exposes a double.

2nd: Can someone please confirm that the proper way to make an indicator's values available within a new indicator, that the following line of code is the correct way to initialize and add an indicator to a new indicator:

//Iniitalize()
Add(IndicatorSource()); // Adds the IndicatorSource

The above assumes that the name of the indicator that I am trying to call is named "IndicatorSource"--and it also assumes that the IndicatorSource indicator does not have any overloads, which it doesn't.

I am getting the following error when I try and add IndicatorSource into the indicator:

CS1502: The best overload method match for 'Ninjatrader.Indicator.IndicatorBase.Add(NinjaTrad er.Gui.Chart.Line)' has some invalid arguments.

CS1501: Argument '1': cannot convert from 'NinjaTrader.Indicator.IndicatorSource' to 'NinjaTrader.Gui.Chart.Line'

Can someone please help me determine what might be causing this error and what the proper way to add an existing indicator to a new indicator so that the existing indicator's values can be plotted?

Thanks,

Thanks, Koganam;

The values that I want to expose from the IndicatorSource are double values, which in the IndicatorSource indicator were:

//Variables
private double seriessum = 0; // Variable to store the series sum over N bars

//OnBarUpdate
series.Set(score); //Where "score" is a type int value that represents the current bar's score and "series" is a DataSeries.
seriessum = SUM(series, serieslength)[0]; // This is where the seriessum variable received its values, which are of type double--AND MOST IMPORTANTLY, THESE ARE THE VALUES THAT I AM LOOKING TO PLOT. seriessum is simply a score count of n bars. Again, these are the values that I am looking to plot.

//Properties
//This is where I publicly exposed the seriessum values as a type double called Seriessum
[Browsable(false)]
[XmlIgnore()]
public double Seriessum
{
get { return seriessum; }
}

Would you concur that my logic (above) is correct?

Thanks, Koganam--I REALLY appreciate your help.

Not quite. If you expose anything other than a Plot, you need to run Update() in the getter.

Here is a reference sample that might get you going much faster. http://www.ninjatrader.com/support/f...ead.php?t=4991

Okay, thanks Koganam; I'll take a look at this either later tonight (after NBA Finals Game 7) or in the AM.


So basically I'm thinking that I'll need to create a new DataSeries in the "source" indicator (which we're calling IndicatorSource here), and then .Set the new DataSeries values to populate the new DataSeries values. Then under Properties expose a new public DataSeries instead of the current double that I am trying to expose now. So that's where my mind is currently at while sitting in front of the TV without having my computer in front of me.


I guess one basic question I have: it is possible to grab a publicly exposed indicator value (ie, the new DataSeries above) and then use that in another indicator, right? Or can you only pull a publicly exposed DataSeries into a strategy (ie, not an indicator).


Thanks for your help, Koganam. You're an all star!

Any object that is public in a namespace can be accessed by any other object that uses the namespace.

Thanks; so I'll assume that your very precise answer means that yes, an indicator or a strategy can access a publicly exposed DataSeries.


Thanks!
