How do I cancel a limit ENTRY order after a partial fill with NinjaScript?

[QTrader]

I have the following two questions on the subject of advanced order management using NinjaScript:

1) How do I cancel a limit ENTRY order after a partial fill with NinjaScript (i.e., stop trading the limit order for the remaining quantity)?

2) How do I modify a limit ENTRY order after a partial fill with NinjaScript(i.e., alter the limit order paramaters for the remaining quantity)?

Thanks,

Jian

Hello QTrader,

Welcome to the NinjaTrader forums!

You can work in IExecution interface to check fill quantity of specific orders.

There is also available order state PartFilled that you can check for.

The reference sample we have on CancelOrder() can help setting this up:

To modify an order: You submit an updated statement with the new parameters.

Hello Ryan,

Thank you very much for your quick & very helpful reply. Just want to confirm that when using the following syntax:

EnterLongLimit
( int barsInProgressIndex,
bool liveUntilCancelled,
int quantity,
double limitPrice,
string signalName
)

to issue a replacement (or modifying) LIMIT ENTRY order after a partial fill, it is the signalName passed as a parameter that will uniquely identify the original LIMIT ENTRY order for order change?

Also, will the IOrder.Token (NOT IOrder itself) object returned from the 2nd (replacement) EnterLongLimit call be different from that of the 1st (orginal) EnterLongLimit call?

Thank you very much for your help!

Yes, it is the signal name that will match the prior order with the new one.

.Token property is no longer used in version 7 for comparing equality. You compare objects directly. For modifying the orders then, you must be update the object references with the new modified order and manage anytime this must be reset.

Thank you very much for your confirmation & additional info provided on .Token. I will upgrade NinjaTrader to Version 7 and look into the features of object references & updates as you described.

Thanks,
