Is it possible to cancel just submitted order?

[alex.nt]

Hi,

I need to cancel a order from OnOrderUpdate handler.

For example, an order has just been submitted so is there any way to cancel this order from within OnOrderUpdate, when it comes there the first time.

Thank you.

Hello,

This can be done if the order is in a working state.

For example:

if (order == myOrderHandle && myOrderHandle.OrderState == OrderState.Working)
CancelOrder(myOrderHandle);

Order states are:

1) Initialized
2) PendingSubmit
3) Accepted
4) Working

Question 1: can I cancel at any status?
Question 2: at what status(es) the cancellation is guaranteed, i.e. there is no chance that order may be filled (at least partially) on exchange?

Hello Alex.nt,

Thank you for your response.

You can cancel at any status, but there is no guarantee that a fill will not occur before the cancel is received by the broker and submitted.

Please let me know if I may be of further assistance.
