IB Rejecting Orders Till Floor Opening

[aa411853]

Last 2 nights I've had trades in the British Pound triggered, and TS fired off the orders, but IB rejects them as follows:

2010-07-22 02:15:09:046 (2010-07-22 06:15 UTC) Order Rejected: TB Order TB207166 U509901 BUY 2 6B 09-10 GLOBEX STOP 1.5204 DAY, TradeBulletId: TB207166, System: BrOR_L , Signal: 3 min. , Reason: Order Message:
Warning: your order will not be placed at the exchange until 2010-07-22 07:20:00 US/Central (399)

I'm using symbol mapping and this works fine because my trades are executed ok during daytime hours. Is there a setting in IB that needs to be changed? From the routing above it appears that the trade is correctly sent to Globex rather than the Floor based contract.

Any help would be appreciated.

Order rejection messages either come from TWS or the exchange. I believe in these cases TWS is just using the Reject message as a warning and your order is in fact still working. You may want to enable orders outside market hours in TWS.
