How to use MetaTrader4.Manager.Wrapper to listening the event of TradeAdded/TradeClosed/TradeDeleted - metatrader4

Question

I wand to listening the event of TradeAdded/TradeClosed/TradeDeleted ,that's my code:
public partial class Demo : Form
{
public static ConnectionParameters conParam = new ConnectionParameters();
public static ClrWrapper mt;
private void Hedera_Load(object sender, EventArgs e)
{
Login();
}
public void Login()
{
conParam = new ConnectionParameters
{
Login = serverConfig.ManageAccount,
Password = serverConfig.ManagePassword,
Server = serverConfig.ManageServer
};
mt = new ClrWrapper(conParam);
List<UserRecord> users = mt.UsersRequest().ToList();
mt.TradeClosed +=new TradeRecordUpdated(this.MyTradeClosed);
mt.TradeDeleted += new TradeRecordUpdated(this.MyTradeDeleted);
mt.TradeAdded += new TradeRecordUpdated(this.MyTradeAdded);
}
public void MyTradeAdded(ClrWrapper mt, TradeRecord tradeRecord)
{
MessageBox.Show("MyTradeAdded");
}
public void MyTradeClosed(ClrWrapper mt, TradeRecord tradeRecord)
{
MessageBox.Show("MyTradeClosed");
}
public void MyTradeDeleted(ClrWrapper mt, TradeRecord tradeRecord)
{
MessageBox.Show("MyTradeDeleted");
}
}
When i trade on the MetaTrader4 client ,I want to get the notify in my C# program.
“UsersRequest” is ok now,but the event does not run.
Where is wrong in my code ?
Can you write an example for me?

Those events are fired only in extended pumping mode. so you have to switch:
public void Login()
{
conParam = new ConnectionParameters
{
Login = serverConfig.ManageAccount,
Password = serverConfig.ManagePassword,
Server = serverConfig.ManageServer
};
mt = new ClrWrapper(conParam);
List<UserRecord> users = mt.UsersRequest().ToList();
mt.TradeClosed +=new TradeRecordUpdated(this.MyTradeClosed);
mt.TradeDeleted += new TradeRecordUpdated(this.MyTradeDeleted);
mt.TradeAdded += new TradeRecordUpdated(this.MyTradeAdded);
metatrader.PumpingSwitchEx();
}
However, after switching into pumping mode, you won't be able to use non pumping methods
