Ninja cannot create strategy after recompilation

[NinjaTrader_AlanP]

Hello rfsettling,

You are attempting to serialize a custom class, which is out of the scope of what our scripting desk supports. This is so that we can maintain a high level of service for all of our clients.

There is a way to do what you’re looking to do, and if you’d like I can have someone reach out with a list of third parties who specialize in C# and can help you with this.

Chelsea did just upload a sample which you may find of interest,

Please let us know if you need further assistance.

For those people who will run across the problem, like me. It can be solved by fixing CopyTo method.

 public override void CopyTo(NinjaScript ninjaScript)
        {
            var ninjaScriptState = ninjaScript.State;

            try
            {
                base.CopyTo(ninjaScript);
            }
            catch 
            {
                //State property must not be copied
                var aStateProp = ninjaScript.GetType().GetProperty("State");
                if (aStateProp != null)
                    aStateProp.SetValue(ninjaScript, ninjaScriptState);

                PropertyInfo[] srcFields = this.GetType().GetProperties(
                    BindingFlags.Instance | BindingFlags.Public | BindingFlags.GetProperty);

                PropertyInfo[] destFields = ninjaScript.GetType().GetProperties(
                    BindingFlags.Instance | BindingFlags.Public | BindingFlags.SetProperty);

                foreach (var src in srcFields)
                {
                    if (src.Name == "State")
                        continue;

                    var aXmlIgnore = src.GetCustomAttribute<XmlIgnoreAttribute>();
                    if (aXmlIgnore != null)
                        continue;
                    var dest = destFields.FirstOrDefault(x => x.Name == src.Name);
                    if (dest != null && dest.CanWrite)
                    {
                        var aValue = src.GetValue(this, null);
                        //this is what is missed in Ninja internals
                        if (src.PropertyType==dest.PropertyType)
                            dest.SetValue(ninjaScript, aValue, null);
                        //Different types. cannot just assign value
                        else
                        {
                            //copying value via xml serialization
                            using (var writer = new StringWriter())
                            {
                                new XmlSerializer(aValue.GetType()).Serialize(writer, aValue);

                                using (TextReader reader = new StringReader(writer.ToString()))
                                {
                                    var serializer = new XmlSerializer(dest.PropertyType);
                                    var aNewValue = serializer.Deserialize(reader);
                                    dest.SetValue(ninjaScript, aNewValue, null);
                                }
                            }
                        }

                    }
                }
            }
        }
