Order has been accepted by TWS / IB. If not, take a look at page "order history" and search for ticket of order being missed. You may get a hint what happened. Also search in page "log" for "rejected". If order failed on TWS / IB side, a "rejected" message is sent to bridge. An order can fail to be transmitted for various reasons:

• Margin violation by new order

• No trading permissions for contract

• Order is close order, but open order not recognized in bridge. This can happen, if open order was sent when bridge was not running.

• Wrong group or profile name when placing an order for FA account. Check out Profile / Group / Account name exposed in MTIBBridge Setup page matching to settings in FA-TWS
  

• Wrong ordersize: Check default Lotsize for 1 Lot in "Symbol Mapping" page
