How to expose non-series indicator data?

[Jellybean]

Hi
I would like some help exposing indicator data to calling strategies. My knowledge of how properties work is not thorough enough and I'd appreciate any advice.
My indicator creates a list of objects whose properties I want to access from one or more strategies (in addition to series values). This is what I've tried. It compiles but I don't get the data I expect.
In the indicator file, outside the indicator class, but within the NinjaScript.Indicator namespace, I define a class SDZone, which has several properties I want strategies to access.


Instances of SDZone are created in the indicator and added to a list of SDZone defined in the indicator.

List<SDZone> zoneList
…
 zoneList.Add( new SDZone(...) );

I have made zoneList a property of the indicator.

[Browsable(false)]
 [XmlIgnore]
 public List<SDZone> zoneList
 { get; set; }

In the strategy, I create a List<SDZone> stratZoneList, and I assign it the indicator property zoneList.

private List<SDZone> stratZoneList;
 …
 stratZoneList = indicator.zoneList;

Within the strategy, I hoped to be able to access the contents of the list created in the indicator like this:

foreach ( SDZone z in stratZoneList )
 {
if ( z == null )

    Print( "z == null" );
  else

    Print( "This is z: " + z.sdZoneProp1.ToString() );
 }

However, although z is never null, its count is always 0.


Any help would be welcome.
Cheers

Hi

I have answered my own question now, and I thought it might be useful to share it.
Note: I'm using NT8 Beta 7

Two key points:

1. My strategy doesn't use the series values of the indicator so I didn't call them. However, if they are not called none of the indicator data is updated. I resolved this by simply assigning the current indicator value to a temporary variable within OnBarUpdate() before any other indicator data is used.

2. You can't just assign a list to a new one and expect the contents to be accessible. I resolved this within the strategy by using the indicator list property directly, e.g.

[SIZE=2]foreach ( SDZone z in indicator.zoneList )
{
   if ( z == null )
      Print( "z == null" );
   else
      Print( "This is z: " + z.sdZoneProp1.ToString() );
}[/SIZE]

Cheers
