I've traded this for a little less than three years now and the CBOT feed has never gone down when I was in front of the screens.
Bloomberg radio just briefly mentioned 'CBOT halting trading of futures contracts ... more in moment' or something like that.
"Hehe, this is my first day live, so if this is what I can expect by CBOT, then I'd better find myself another vehicle to trade " Heck of a way to start, So did you get any live trading in ?
