switch from manual trading to auto

[akkiss]

Hi, please give me some advice. I want to make a position, then switch on an automated strategy to set the stop in every bar, and the position will close in that way. What is the best way, when I have an open position, and I want to be managed it by a strategy. What is the right set of the "wait until flat before live", or "immediately submit live ..." and the sync account position would be false or true. And there is a method to scan the live positions? So, my goal is:
- I start a position manually
- Then I start a strategy, wich will recognise the position, and from this time this position will be contorlled by the strategy (stop, exit...)

Thank you for advance

Hello akkiss,

Using supported methods, strategies are not able to detect orders placed outside of that instance of the strategy.

You may be able to achieve this with unsupported code, but the NinjaTrader Support will not be able to assist.

To point you in the right direction, below is a tip of unsupported code you may find helpful.

foreach (Account acct in Cbi.Globals.Accounts)
{
if (acct.Positions != null)
{
// print information about each position
PositionCollection positions = acct.Positions;
foreach (Position pos in positions)
{
Print(pos.Account.Name + " " + pos.Instrument + " " + pos.MarketPosition + " " + pos.Quantity + " " + pos.AvgPrice);
}
// print information about each order
OrderCollection orders = acct.Orders;
foreach (Order ord in orders)
{
Print(ord.ToString());
}
}

Hi ChelseaB
Thank You for your answer. I see, that this script will dump the parameters of the running positions to the output window. In our case we have only one position, but how will accept it the Ninja strategy?
Best regards Akos

Hello akkiss,

The unsupported code tip is meant to go in a strategy and detect your manual orders.

Hi ChelseaB

Sorry, it isn't clear. After this, I can use the managed or unmanaged part of order commands, to enter submits? Need it to set the sync parameters in Ninja? What kind of array the Cbi.Globals.Accounts?
Sorry for the stupid questions I can't see the solution yet.


Kind regards

Hello akkiss,

You would likely use the unmanaged approach as any manual order that is detected by the strategy will not be added to the Strategy Position.

You would call this when you wanted to detect that a manual order has been placed.

Your inquiry was to detect a manual order that was placed and submit protective orders to cover it correct? If so, you need to detect the manual order. This code is to detect the manual order.

The code can pretty much be added anywhere in a method. So you want to detect the orders when the script starts then add this code to OnStartUp. If you want to detect this on a button click then add a button click and run this code. etc.

Hi ChelseaB
I have to think through your advice, that will be the solution!
Thank you for your time

Hí ChelseaB
I have a new question, sorry I'm not experienced in C#, but Im studying. I see, we got the Order object. But I need the IOrder read only interface, if I want to use the ChangeOrder, or CancelOrder methods. How can I generate from Order object an IOrder interface?
Thank you for your time

Hello akkiss,

To create an IOrder variable to store the order:
private IOrder myOrder = null;

To cast an existing order object to an IOrder variable:
myOrder = (IOrder) ord;

Hi ChelseaB
Thank you for your answer. I inserted the lines. First to the variables, th seconds to the OnBarUpdate methods. I got an error warning, from the editor, so I inserted a new line to the variables:
private Order ord = null
The compiling was succesfull, but the result is not very good. In this script I want to print out the parameters of the myOrder, wich is equal the ord, wich shows the running ("hand-made") position. The first part of the script contains your one in the OnStartUp method, then comes the OnBarUpdate. It contains the line from your last letter
myOrder = (IOrder) ord;
and anothers, to print the myOrder.

This:

protected override void OnBarUpdate()
{

if(Historical)
return;

myOrder = (IOrder)ord;
Print("+++++++++++++++");
Print (ord.ToString()); //secondary it was deleted
Print(Time[0].ToShortTimeString());

if(myOrder != null)
{
Print("writing out the myOrder");
Print (myOrder.ToString());

// ChangeOrder(myOrder, myOrder.Quantity, 0, stopPrice);
// Print("betette a stopot");
}


Print("end of the OnBarUpdate ");
}


}

#region Properties
// [Description("")]
// [GridCategory("Parameters")]
// public int MyInput0
// {
// get { return myInput0; }
// set { myInput0 = Math.Max(1, value); }
// }
#endregion

}

I made a position in the chart trader, then started this script, (EURUSD, M2). First in the output window the order parameters appeared, then I got an error warning:
**NT** Error on calling 'OnBarUpdate' method for strategy 'STteszt1/b14e81b9bb5547ad965a651c86d672e1': Object reference not set to an instance of an object.
I can't understand it. Second, I ereased a line after the +++++++++++++++++, (remarked on the script) and this case I didn't get the error warning, but the printing was not succesfull too.
What would be the failure?
My goal is: First make a position, then start a script, wich reconise the position, and add to it a stop, or profit target, or exit the position. I took your advice, but may be, that the right place of "myOrder = (IOrder) ord;" is not in the OnBarUpdate method? I hope You can help me.
Thank for advance

Hello akkiss,

This is unsupported code that I cannot assist with.

However, this thread will remain open for any community members that would like to contribute.
