in some cases, the take profit order failed to be accepted
the braket order is as following:
parent order:? limit? buy/sell with 1 minute timed auto cancel
child orders:?? 1 stp order and 1 lmt order


in this case, the profit taker lmt was rejected, and hoving over the 'i', it says 'Rejected by system, parent Id is cancelled', and I have verified that it is NOT a partialy fill, the prent order are? filled in full.

one of the child orders was accepted, in this case the stoploss order.

can someone help me explain what is going on?

Thanks
Jeff

most of cases, things are ok, such as the following:

Jeff,
Do you have the transmit flag on the first two orders in the bracket set to False? If the parent fills before a child order is received, it won't be able to attach.?

All orders except the final child should be transmit false. Only the final child should be transmit true.

thanks, I have just changed to what you said, as shown in my posting, hoping it will be gone tomorrow
