Full OrderState Lifecycle of Cancelled Order

[jeronymite]

When a Limit or StopMarket Order is Cancelled, what is the full lifecycle of the OrderState of the Order?

It would presumably initially enter OrderState.CancelPending and progress through to OrderState.CancelSubmitted and finally OrderState.Cancelled. Will it pass through any other OrderStates, even briefly; e.g. OrderState.Working?

Thanks.

Hello jeronymite,

Thank you for writing in.

The order states may be observed in the Log tab of the Control Center and we have the order state definitions in the Help Guide here:

https://ninjatrader.com/support/helpGuides/nt8/order_state_definitions.htm

Typically, a Limit or Stop Market order will be in the Working state after it is accepted and before the action to cancel the order is submitted. Then it hits Cancel Submitted and Cancelled. Here is an example where I submitted a simulated limit order in the SuperDOM then cancelled it:

The order states were Submitted -> Accepted -> Working -> Cancel Submitted -> Cancelled. There is no specific lifecycle of orders, after being submitted they could be changed, rejected, partially filled, etc.

Please let us know if we may be of further assistance.

Thanks, NinjaTrader_Emily. I know the overall states of Orders well. I ask about the Cancel "lifecycle" to ensure I know what is possible. I want to know if it is definitive that once a Cancel Order is executed in an AddOn, that the Order can only go through the sequence CancelPending, CancelSubmitted and finally Cancelled. Exceptions might be if the Cancel does not reach the Order before it begins to execute (resulting in an Unable to Cancel Order error), but if it does reach it while it is still Working (or earlier), is it definitive to follow that sequence?

Thanks.

Hello jeronymite,

Thank you for your reply.

The sequence of an order cancellation is not definitive. For example, in the example from my previous post the order went from Working to Cancel Submitted and then Cancelled. The order did not reach a state of Cancel Pending.

I appreciate your patience. Please feel free to reach out with any additional questions or concerns.

Thanks, NinjaTrader_Emily. To confirm, after you submitted the Cancel, the Order passed through the Working state? And was that Sim/Demo/Live?

Thanks.

Hello jeronymite,

Thanks for your response.

The order did not pass through the working state after the cancellation. This was a simulated order on the Sim101 account.

Here is an example where I submitted a simulated limit order in the SuperDOM then cancelled it:

https://www.screencast.com/t/4drr7vf5t

The order states were Submitted -> Accepted -> Working -> Cancel Submitted -> Cancelled

As previously mentioned and shown in the screenshot, the order was Submitted, then Accepted, then Working. Next is when I pressed the cancel button, which resulted in Cancel Submitted and then Cancelled. You previously asked me to clarify if the "Order can only go through the sequence CancelPending, CancelSubmitted and finally Cancelled." and my response to that is no; this sequence is not guaranteed nor definitive. In my example, the order did not ever go through a state of CancelPending which is why I brought it up as an example to demonstrate this point.

I appreciate your patience and hope this helps to clarify. Please let me know if I may be of further assistance.
