Pending Order cancelled

Was running SIM account and the s/w announced Pending Order,(Did a Long Limit ) then shortly there after it stated order cancelled.
What causes this to happen? It was never logged as a order.

Hi bbucha_stk,

I'm not sure what this may have been. How did you place the order? Can you send in your log / trace files and we can see what happened in the platform at this time. Use Help > mail to support feature and in subject write Attn: RyanM. Please also let us know the exact time you heard the sound if possible.

I am doing a
EnterLongLimit(DefaultQuantity, Typical[0] + -2 * TickSize, "");
EnterShortLimit(DefaultQuantity, Typical[0] + 2 * TickSize, "");
I was reading the Ninja description and the parameter
liveUntilCancelled which is part of the IOrder constructor which I am not currently using, but does my limit order get auto cancelled at close of bar if not filled?

Correct, per default limit orders expire on the next OnBarUpdate() call if not resubmitted or issued with liveUntilCancelled.
