C# use Linq to pull data from xml

I have problem with building object holding XML data using Linq. For example, I have XML data in url http://api.eve-central.com/api/marketstat?typeid=34&usesystem=30000142 . In MarketStat class I want to hold type id value and in MarketValue class array I want to hold volume avg max min stddev median percentilevalues of buy sell all nodes. I have never used linq so far so please help me fix my problem in code below:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Xml.Linq;

namespace ConsoleApplication1
{
    internal class MarketValue
    {
        public int Volume { get; set; }
        public double Avg { get; set; }
        public double Max { get; set; }
        public double Min { get; set; }
        public double Stddev { get; set; }
        public double Median { get; set; }
        public double Percentile { get; set; }
    }
    internal class MarketStat
    {
        public string Name { get; set; }
        public MarketValue[] MarketValueses { get; set; }
    }
    internal class Program
    {
        private static List<MarketStat> list;
        internal static void Main(string[] args)
        {
            list = (
                from e in XDocument.Load("http://api.eve-central.com/api/marketstat?typeid=34&usesystem=30000142").
                    Root.Elements("marketstat")
                select new MarketStat
                {
                    Name = (string) e.Element("type id"),
                    MarketValueses = (
                        from mv in e.Elements("buy")
                        select new MarketValue
                        {
                            Volume = (int) mv.Element("volume"),
                            Avg = (double) mv.Element("avg"),
                            Max = (double)mv.Element("max"),
                            Min = (double)mv.Element("min"),
                            Stddev = (double)mv.Element("stddev"),
                            Median = (double)mv.Element("median"),
                            Percentile = (double)mv.Element("percentile")
                        }).ToArray()
               }).ToList();
         }
    }
}
