short question about iOrder OrderState

[Locke]

I came across the following snippet of code:

if (longEntry != null && longEntry == execution.Order)
{
if (execution.Order.OrderState == OrderState.Filled
|| execution.Order.OrderState == OrderState.PartFilled
|| (execution.Order.OrderState == OrderState.Cancelled && execution.Order.Filled > 0))
{ ... stuff }

The first two if checks I understand - check if the order was filled or partially filled.

But what about the third check? The OrderState of an iExecution Order property can be cancelled and still have it have some type of fill? I'm trying to understand how we can get to this point. We are in OnExecution and to be in this block, longEntry == execution.Order - so how can we have canceled the order and still have it reach this point?

That's my short question - how and why does this happen? If this is really necessary there are probably some other holes in my coding that need plugging. THANKS NINJAS.

Hello Locke,

This snippet of code:

(execution.Order.OrderState == OrderState.Cancelled && execution.Order.Filled > 0)

checks if the order was partially filled and then cancelled. The Order.Filled integer returns the quantity filled so far. For example: If the quantity is 1 and the order is cancelled, then the order was partially filled (although it wouldn't have the PartFilled order state).

For more information on the various order states, please see the IOrder section of the help guide here: http://ninjatrader.com/support/helpG...nt7/iorder.htm

Please let me know if you have any questions.

Thanks Michael, this is clear now.
