Accessing Rectangle lists

[APA Zones]

Hi,
I'm trying to make data availbe to my strategy that I'm writing from an indicator. However the indicator creates a lists of rectangles and I want the strategy to read this list. I'm having issues exporting that list. Here's how it looks so far

 
[Description("The supply zones values and bounce count according to active rectangles")]
[Browsable(false)]
public List<IRectangle> SupplyZones  //provides access to the supply list so that the strategy can use this list.
		{
			get { return supplyZones; }
		}

Then when I use this code I can compile just fine, however when I apply the indicator to a new chart I get a serialization error(attached). But I can double click the 'ok' box and it will apply the indicator to the chart. However the real issue is getting this list to be seen by other scripts or market analyzer.

Any help would be great.

doubletop, unfortunately we could not directly support the access of exposing list objects / members, can't you expose the information needed through a dataseries perhaps?

For the serialization issue, please try adding [XmlIgnore()] tags to your public property definitions.
