Check the existing order Name

[NRITV]

Thank You NinjaForum

I am trying to validate for an existing order name and if it exists then placing a second order . here is an example:
//

var order2 = Orders.FirstOrDefault(O => O.Name == "LD");

{
if ((order2 != null) && ((Closes[0][0] < SMA(10)[0])))
{

EnterLong(1, "LD2");
return;
}
}

The above code is not returning the First order "LD"

Could you please help me.

Thanks

Hello NRITV,

Where is the Orders collection coming from?

Is this something you created yourself?

What code is putting orders in this collection?

Hello Chelsea B.

here is the code for the first order entry:
if ((Position.Quantity == 0) && ((Closes[0][1] > SMA(10)[0]) )
{
EnterLong(1, "LD");
return;
}

Here is the code for checking the above order name:
//
var order2 = Orders.FirstOrDefault(O => O.Name == "LD");

{
if ((order2 != null) && ((Closes[0][0] < SMA(10)[0])))
{

EnterLong(1, "LD2");
return;
}
}

Not sure about the order collection. Could you please help me.

Thanks

Hello NRITV,

Orders.FirstOrDefault(O => O.Name == "LD");

Where is the Orders collection defined?

What code is adding orders to this collection?

If there isn't any, then likely this is an empty collection and nothing is going to be returned from .FirstOrDefault()?

Hello Chelsea

how do I define order collection or is there any other way to code for my above requirements?

I just want to validate if there is an existing order name "LD"

Thanks

Hello NRITV,

As an example if this Orders variable is a List<Order> object, it would be declared as:
private List<Order> Orders;

And instantiated in OnStateChange() when State is DataLoaded as:
Orders = new List<Order>();

And elements added to the list from OnOrderUpdate() as:
if (!Orders.Contains(order))
{
Orders.Add(order);
}

Below is a link to an educational site on using lists.

The collection also could be an array, or dictionary, or sortedlist, or other data structure type.

What kind of collection have you coded the variable Orders as in the code of your script?


Also just to confirm, your post is in the NinjaTrader 7 section of the forums as this is for NinjaTrader 7, is this correct?
