Unmanaged orders error

[guillembm]

Hi,

I'm starting to work with unmanaged orders and I 'm getting my first errors.

When submitting the order I get this error: "**NT** Error on calling 'OnOrderUpdate' method for strategy 'HFTSimple/5ec21fb573094c7d9525423c79ed8173': Object reference not set to an instance of an object."

The submit order that gives the error is:

MyExitOrder = SubmitOrder(0,OrderAction.BuyToCover,OrderType.Lim it,Position.Quantity,AskPrice,0,"AllOrders","");

This Submit is done after cancelling a previous Limit order to take profits:

CancelOrder(ProfitLimit);

Hello,

Thanks for the note.

Make sure you are doing null reference checks before trying to access iOrder objects is most likely what you are missing.

entryOrder != null

I look forward to assisting you further.

Thanks,

when I submit the order I Print the value and I know is null.

if (MyExitOrder == null)
{
MyExitOrder = SubmitOrder(0,OrderAction.BuyToCover,OrderType.Lim it,Position.Quantity,AskPrice,0,"AllOrders","");
}

With TraceOrder = true I get this error:
9/13/2011 4:15:00 PM Entered internal SubmitOrder() method at 9/13/2011 4:15:00 PM: Action=Sell OrderType=Limit Quantity=100 LimitPrice=46.84 StopPrice=0 OcoId='AllOrders' Name=''

Why the error appear in OnOrderUpdate()?

Perhaps is a problem of the token?

if (MyExitOrder != null && MyExitOrder.Token == execution.Order.Token)

Right yea this would be an issue.

You can't have MyExitOrder be null and then also check it to see if it has a token value. The token value check would need to come inside of the null check.

Let me know if I can be of further assistance.

You mean this?

if (MyExitOrder != null)
{
if (MyExitOrder.Token == execution.Order.Token)
{


}
}

Exactly,

You would need to make sure you do this with every time you try to access information in an iOrder object.

I look forward to assisting you further.
