Quick IOrder questions

[eurostoxx trader]

I have just been finishing up a simple strategy with IOrders and I had the following questions

1) When using the OnExection() method, the method will update on the event automatically, so I dont need to call it anywhere (because I tried calling it and I got an error)

2) If that is the case, will the OnExection() method also update on the exit of a position? Does the method know the difference between entreris and exits? Is there a way to call just when the entry is filled

3) With the IOrder I added a Profit and loss target (which I hope i can do), that I assume are submitted when the order is first executed on the entry. I want to cancel those Profit and Loss target after XX bars. So I called the CancelOrder() method after my counter reaches XX, and canceled the original order. Are the profit and loss targets treated as member of the original order, or do I need to make new orders for each

Thank you kindly

bah I just found the SampleOnOrder Upadte strategy. So I guess the orders are not links, though I do remember seeing something for OCO orders.

No big deal, so I guess I have to make separate stop and profit loss orders. Kind of annoying but then I do get to have more control over them

Cheers previous material on the forms!

I am happy you figured it out.

last question, which I guess I will find out very soon when I try it on the sim, but to update an IOrder (say to move the price up or down) do I need to delete the old intance of it and then make a new one, or if I just create a new one, will it delete the old one, assuming that same signal name.

From the code I have been reviewing it seems I dont need to cancel it

eurostoxx,

You can simply resubmit the order at the new price.

Here is an example : http://www.ninjatrader.com/support/f...ad.php?t=33998

excellent. Thanks. Now I just have a little problem entering orders within the OnExecution() method.

On historical bars, I am getting an error for my exit and stop loss order. Any ideas?

Here is what I am doing

if (myEntryOrder != null && myEntryOrder == execution.Order)
{
// do a bunch of stuff
//Set the profit and loss orders
myExitOrder = ExitLongLimit(0, true, 1, exit_price, "signal1_exit", "signal1");
myExit_StopOrder = EnterLongStop(0, true, 1, exit_price_stop, "signal1_exit_stop");
if (myExitOrder != null && myExitOrder == execution.Order)
{

CancelOrder(myExit_StopOrder);

}

if (myExit_StopOrder != null && myExit_StopOrder == execution.Order)
{
CancelOrder(myExitOrder);

}
}

}

ahh I did the if(historical) and it seems to stop the error.

So if I try to cancel an order that is null, I will get an error, but will the script continue to run? Or do I need to check first

eurostoxx trader,

Please find a reference sample on checking for Null orders below.

thanks, I'll add the check to the line.

So if you have a stop exit & stop loss order, if one of those is executed, then the other is cancelled immediatly? That is where i was getting the error, trying to delete the other

eurostoxx trader,

Are you using the stop exit and stop loss for the same purpose?

Here is a thread on using stop losses creatively : http://www.ninjatrader.com/support/f...t=food+thought
