One possible solution I think I�ve come to is keeping a list of open execution.

That is when OnExecution is called to open a solution position (�Long Entry 1�) add it to a list for Open Executions.

Code

openExecutions.Add(execution);

Also we need to remove it when the execution is closed

Code

else if (execution.Order.Name != "" && (execution.Order.Name.Contains("Long Target") || execution.Order.Name.Contains("Long Target")))
                {

                    string orderNumber = execution.Order.Name.Substring(execution.Order.Name.Length - 1);

                    int indexNum = 0;

                    foreach (IExecution y in openExecutions)
                    {

                        if (y.Order.Name.Contains(orderNumber))
                        {
                            indexNum++;
                            break;
                        }

                        indexNum++;

                    }

                    openExecutions.RemoveAt(indexNum);

                }

It relies on the fact that we are keeping a unique number to append to the back of the IOrder text. I do this by just having a method to increment it each time it is called (might better doing it via a Property?).

Code

protected string GetOrderNumber(IOrder order)
        {

            return order.Name.Substring(order.Name.Length - 1);

        }

I think someone mentioned IOrder Tokens, I thought that Tokens were not always unique?

Any thoughts greatly appreciated.

Cheers,

Hi,

I've found a better solution for parsing the number from the order number string. I would recommend this method above the previous one posted. The previous isn't as robust.

Code

protected string GetOrderNumber(IOrder order)
        {

            string b = string.Empty;

            for (int i = 0; i < order.Name.Length; i++)
            {
                if (Char.IsDigit(order.Name[i]))
                    b += order.Name[i];
            }

            return b;

        }

Hallo friends,

thank you for this interesting thread. How difficult it is to find the right indications sometimes...!

I posted a -still unanswered- thread on Ninja forum, (though my username there is different). I cannot paste links here because I am newbie, but it goes about "Managing multiple trades without string names".

From what I have read here, it seems that the only solution is parsing strings, is it correct?

Any further suggestions?

Bye

Not sure about backtesting but the following will work in a live scenario:

In OnStartUp() method subscribe to the Execution event

Code

acct.Execution += new Cbi.ExecutionUpdateEventHandler(ExecutionUpdateHandler);

Then watch for the events:

Code

        List<Order> orderList = new List<Order>();
        private void ExecutionUpdateHandler(object sender, ExecutionUpdateEventArgs e)
        {
            Print("Execution Event: " + e.ToString());
            bool orderExists = false;
            foreach(Order _ord in orderList)
            {
               if( _ord.OrderId == e.Execution.Order.OrderId)
               {
                   _ord.OrderState = e.Execution.Order.OrderState;
                   orderExists = true;
                   break;
               }
            }
            if (orderExists == false)
            {
                orderList.Add((Order)e.Execution.Order);
            }
                              
        }

finally, important, in OnTermination() unsubscribe:

Code

acct.Execution -= ExecutionUpdateHandler;

This should populate the list with new Orders and modify the existing ones. There might be some typos in the code, but that's the general idea. Use at your own risk.

Here are some others to play with:

Code

	a.OrderStatus += new Cbi.OrderStatusEventHandler(OrderStatusUpdateHandler);
	private void OrderStatusUpdateHandler(object sender, OrderStatusEventArgs e) 
	{
                 	 Print("Order Update event:  " +e.ToString());
	}

	a.PositionUpdate += new Cbi.PositionUpdateEventHandler(PositionUpdateHandler); 
	private void PositionUpdateHandler(object sender, PositionUpdateEventArgs e)
	{
		Print("Position Update event:  " +e.ToString());
	}

	a.AccountUpdate += new Cbi.AccountUpdateEventHandler(AccountUpdateHandler);
	private void AccountUpdateHandler(object sender, AccountUpdateEventArgs e)
	{
		Print("Account Update event:  " +e.ToString());
	}

	a.Connection.ConnectionStatus += new Cbi.ConnectionStatusEventHandler(ConnectionStatusHandler);
	private void ConnectionStatusHandler(object sender, ConnectionStatusEventArgs e) 
	{
		Print("Connection Status event:  " +e.ToString() +a.Connection.Accounts);
	}

	// don't forget to clean up:
	protected override void OnTermination()
	{
		Print("Removing event handlers from account " +a.Name);
		a.Execution -= ExecutionUpdateHandler;
		a.OrderStatus -=  OrderStatusUpdateHandler;
		a.PositionUpdate -= PositionUpdateHandler;  // AccountUpdate
		a.AccountUpdate -= AccountUpdateHandler;
		a.Connection.ConnectionStatus -= ConnectionStatusHandler;
	}

Good luck.
