Same problem here, using J-Trader and GHCO Send an order (sell1 ES march 03 @892.00) Order remained (S) which means send to exchange I directly called GHCO (At this time ES traded @891.00) ES rises during the phonecall (They're on the other line with the exchange) and suddenly I get a fill (sell 1 ES @892.00) when market is trading @ 893.25 This is why I use Advanced Futures / GHCO. They covered the trade for me @ 892.00 (and rebated commissions) While writing this I see ES @ 891.00 (So I would have had a positive trade)...... Still very happy with the service I received.
Maybe if any of the three AF customers were trading ES preopen perhaps they could tell us if AF experienced the same outage when GLOBEX had its network problems.
