I've just started trading the eminis... Question is - on IB, the ES and NQ seem to grey out on the TWS. This happens around 15 min after closing and lasts maybe 20 min. Is there a reason for this or is this just Globex or an IB quote feed problem?
The Globex is closed from 4:15 to 4:45 EST. Your broker may be down longer for system work. (Mine stays down until 6:30)
