Json serialize problem

[vyacheslav-skvortsov]

I want to perform "Order close by". This is my code:

MqlTradeResult result;
_apiClient.OrderSend(new MqlTradeRequest
 {
       Action = ENUM_TRADE_REQUEST_ACTIONS.TRADE_ACTION_CLOSE_BY,
       Position = request.Ticket,
       PositionBy = request.OppositeTicket,
}, out result);
return result;

I dont need to send Symbol property. After json serialization MtApi5 advisor takes this json:
{"RequestType" : 3,"TradeRequest" : {"Type" : 0,"Magic" : 0,"Order" : 0,"Type_filling" : 0,"Sl" : 0,"Tp" : 0,"Deviation" : 0,"Action" : 10,"PositionBy" : 15052,"Type_time" : 0,"Position" : 0,"Price" : 0,"MtExpiration" : 0,"Stoplimit" : 0,"Volume" : 0}}-There is no Symbol property and it leads to errors: "Failed to parse parameter TradeRequest" on response and "JsonToMqlTradeRequest: failed to get Symbol from JSON!" on Advisor.

I modified MqlTradeRequest class like this:

public class MqlTradeRequest
    {
        public ENUM_TRADE_REQUEST_ACTIONS Action { get; set; }           // Trade operation type
        public ulong Magic { get; set; }                                 // Expert Advisor ID (magic number)
        public ulong Order { get; set; }                                 // Order ticket

        public string Symbol { get; set; } = String.Empty;               // Trade symbol

Now everything is ok. Could you fix this, please, in next releases?
