Quote from Bankedout:
Strange stuff. I trade my IB account using Medved QuoteTracker. Each day to trade ES or NQ all I have to do is use the integrated trading in the QT program. Today, I tried to buy and sell contracts multiple times, but nothing goes through. According to my TWS bulletin, GLOBEX has been "available" since 09:55:14 EST, but for me it's not available. I almost decided to trade the YM instead, but I like the liquidity of ES/NQ too much to give it up. Before this point, I have never had a problem with IB. Although I haven't been with them THAT long.

It turns out the problem is Medved Quote Tracker. It for some reason stopped sending my orders to IB's TWS program. It still takes the streaming prices though. Strange. I realized this morning when my orders wouldn't go through, that the problem must be QT. Sure enough I entered orders in TWS instead and everything was fine.
