setting IOrder when the position closed

[akkiss]

Hi
In my startegy first I defined IOrder entryOrder, then entryOrder=EnterShort(), then I set the stoploss with SetStopLoss.
It works. My question is: When the position closed (because the price equals the stoploss), is the entryOrder set to null automatically, or I have to detect the closing of the position, and set the entryOrder to null.

Kind regards
Akos

If you must, you will have to nullify your IOrders when flat.

I have never seen the need to do so. After all, I intend to reuse the IOrders, and they are fully assignable, so why nullify them?

Hi Koganam
Thank you for your answer. The IOrder object is readable only, but is it nullable, when the position is flat?
The background of my question:
I want to use the IOrder object as a "flag", to know if there is an opened position or there isn't. It works only if he IOrder is null everitime, when there is no position.
Or I need a method, or something, to show that at the moment there is live position or there isn't.

Kind regards

if (Position.MarketPosition == MarketPosition.Flat)
{
//means that there is no position
}

That is completely independent of the existence or state of any IOrders.

Hello Akos,

Thank you for your post.

You may run into an instance where you assign the IOrder to the entry order but the order does not fill before the next bar update and the check for MarketPosition.Flat is true and thus sets the order back to null. So you may wish to set the order to null when the Stop Loss fills and check that it is null before entering into a new position:

// in OnBarUpdate()
if(myEntryCondition && myOrder == null)
{
myOrder = EnterShort();
}
// in OnOrderUpdate()
if(order.Name == "Stop loss" && order.OrderState == OrderState.Filled)
{
myOrder == null;
}
