Arrays of DataSeries

[DLatNT]

Is the above legal? I am having problems with the "Object reference not set to an instance of an object" even though I set variable and initialize it
public class MM : Indicator
{
#region Variables
#endregion

public DataSeries[] BB;
int[,] McM;// = new int[4,3];
private double[] dMACDS;

/// <summary>
/// This method is used to configure the indicator and is called once before any bar data is loaded.
/// </summary>
protected override void Initialize()
{


int[,] McM= {{12,26,10},{31,68,26},{51,110,42},{6,13,5}};


BB[4] = new DataSeries(this);
etc

DLatNT, unfortunately arrays / arraylists (later are easier to maintain) are more general C# topics and thus outside of the scope that we can offer support here for. BB is either a NinjaScript DataSeries object or an array but not both. Also DataSeries should be exposed using those techniques here :

Thanks Josh.
So if I use any arrays in a variable declaration and then initialize it in Initialize() I still get that Object error. The only way I can avoid it is by putting this code to initiliaze in OnBarUpdate(). Is this correct? This is very unusual setup? My programming skills are rusty but this very basic staff.
Can you point me to a solution? You should have a debugger.

You would need to ensure you include checks for access while the array / object is null / emtpy, this should not happen. If it works for you in OnBarUpdate(), then try moving this code section to OnStartUp() in NT7 : http://www.ninjatrader.com/support/h.../onstartup.htm

For professional debugging, please check into using Visual Studio in connection with NT :
