Suggestion on NtDirect dll and OrderStatus

[Atomic]

One of the functions that uses this dll is the NTOrderStatus, which returns one of the following strings:

Initialized
PendingSubmit
Accepted
Working
PendingChange
PendingCancel
Cancelled
Rejected
PartFilled
Filled

This is fine except that repeated calls of the OrderStatus function will drive a memory leak which can eventually crash the TradeStation platform. Functions that return an integer do not have this problem or if they do, it is negligible. I suggest either modifying the NtDirect dll to use integers for the order status function return or provide your client with an alternate version which would use integers instead of strings. For existing users the conversion of the integer back to string can be done in the order status function so their existing code will continue to work.

Thanks.

Hello Atomic,

Thank you for providing us with this enhancement request. I've sent it into our development team and they will be tracking this request using ID # #2501

Please let me know if there is anything else I can do for you.

Hello,
My 3rd-party program crashes after many repeated calls to OrderStatus (for a limit order in the working state), I assume due to this memory leak.

I'm using NT 7.0.1000.31.

Is there a workaround? Is the leak fixed in NT 8?

Thanks,

Hello N4Apound,

Thank you for writing in.

I will be checking with development in regards to ID 2501 as mentioned previously in the thread.

Hello N4Apound,

There have been no changes made in regards to this functionality.

Please, let us know if we may be of further assistance.

Hi Zachary,
Thanks for checking. If I understand correctly then, there have been no changes to NT8 that would address this memory leak.

Is there then a recommended workaround?

[NinjaTrader_ZacharyG]

Hello N4Apound,

Outside applications would be outside the realms of platform support, however, I would suggest calling OrderStatus less frequently in your application to see if this resolves your memory leak.

[N4Apound]

Thanks Zachary, I'll try that.

Hello mrduongonline1,

Thank you for writing in and welcome to the NinjaTrader Support Forum!

There has been no change to the functionality of OrderStatus when used with outside applications in NinjaTrader 8.

Please note that outside application functionality would be outside the realms of platform support.

Is there anybody there finding a solution to fix this issue? i am using tradestation, and going to use ninjartrader as broker since cheap commission and multi accounts. If there is no sulution, we have to use market order always which is not good.

Thanks,

Hello ccl3093,

Thank you for your post.

Can you detail what you are seeing that is not resolved in regards to the context of this thread?

[ccl3093]

Users below compliant the NTOrderStatus causing memory leaks when call it from Tradestation to check order's status. The support team said which is not fixed in NT 8.0 since it beyonds the realm of support.

Thanks,

I will try it

I don't understand why the issue is beyond the realm of support. The purpose of NTOrderStatus is for TS users to send order to NT which NT can make commissions from. Plus, memory leak is not tough to fix these days.

Thanks,
