Is it possible to ZeroFormat a List?

Question

I want to serialize a list of a class type:

private static List<TradeData> Trades = new List<TradeData>();

[ZeroFormattable]
private class TradeData
{
    [Index(0)]
    public virtual string Symbol { get; set; }
    [Index(1)]
    public virtual DateTime utcDT { get; set; }
    [Index(2)]
    public virtual int SignedAmount { get; set; }
    [Index(3)]
    public virtual double MidPrice { get; set; }

    public TradeData()
    {
    }
}

But I get the error below when I try to do this operation:

var zf = ZeroFormatterSerializer.Serialize(Trades);
