question regarding orders in orderState=CancelPending

[elirion]

Hi NT experts,

If an order is having orderState=CancelPending, can it still execute when the right condition is met ?

if yes, is there any way for me to block or prevent the execution ?

Hello elirion,

Thank you for your post.

No, if an order's state is CancelPending, this means that NinjaTrader has sent a request to the exchange to cancel the order. It will not be able to execute, and you will likely see an error if the strategy attempts to submit the order, similar to:

Order='XXXXXXXXXX/XXXX Name='XXXX' New state='Rejected' Instrument='XX XX-XX' Action='X' Limit price=X Stop price=X Quantity=X Type='XX' Time in force=XX Oco='' Filled=0 Fill price=0 Error='Unable to submit order' Native error='Order 'XXXXXXXXXXXXX' can't be submitted: order status is CancelPending.'

Please let us know if you have any further questions.

Hi Gaby,


I am running my strategy on a simulated account. Basically I went short and price hits my profit target and I cancelled my stoploss order.
However price went up and trigger my stoploss. This resulted in a stray long position.

The sequence of of status change goes from CancelPending => Working => Filled. If this is not the intended behaviour, I take it as there is some issue with the demo server ?

I am not too worried if the production server will not exhibit this behavior: a CancelPending order will never execute.
