Documentation Clarification: OrderId not unique

[vantojo]

Documentation Clarification: The property <Order>.OrderId is NOT a unique value, since it can change throughout an order's lifetime.


My strategy is always going to start when the Account/Instrument is flat....no orders will be placed until State.RealTime

So, in this case is OrderId static and will not be changed?

Under what circumstances doe the OrderId change?

Hello vantojo,

An order id will change as it comes back from a broker in real-time.

Hello Chelsea

1) How does this relate to GetRealtimeOrder()?

2) How do I get the broker supplied order?

3) OnOrderUpdate?

4) How does this relate to CancelOrder()? Do I need the broker supplied order to CancelOrder(), or the order assigned by Ninja when the order was placed/submitted?

sorry, but the documentation is not clear to me...

Hello vantojo,

This would not relate to GetRealtimeOrder(). GetRealtimeOrder() is used when an order is submitted in historical data, is still working in real-time data, and you want to modify the order.

The order will update in OnOrderUpdate() with the new OrderID.

Yes, OnOrderUpdate() will run each time the order changes states.

This does not relate to CancelOrder(). CancelOrder() will cancel an order, no matter what the ID is, by supplying an order object.

Ok I get it...duh.

The Order object contains the Order Id.

Order Id is not used to CancelOrder(), the Order object is used.

My code is ok.

thanks

:-)
