SubmitOrder() or ChangeOrder() in UNManaged structure

[Locke]

Hi Ninjas.

Do you HAVE to call ChangeOrder() to modify an order when using Unmanaged, or can you simply overwrite the IOrder object with another call to SubmitOrder() ?

It's coming up for me in OnExecution() while dealing with partial fills - it would be simpler if I could just use SubmitOrder() for both cases of filled and partially filled orders. Of course, if this breaks something or introduces a problem not easily seen, I don't want to do this.

Thanks guys!

Hello Locke,

Thank you for your inquiry.

If you wish to modify an already existing working order, the call to ChangeOrder() is necessary.

Unlike the Managed approach where you could modify a working order by calling the entry order method again with your new parameters, the Unmanaged approach requires the utilization of the ChangeOrder() method.

Please read the NinjaTrader help guide at this link for more information on using the unmanaged approach of ordering: http://ninjatrader.com/support/helpG...d_approach.htm
