I had bad quotes in esignal all day and couldn't see where most stocks were trading within 60 cents in the last hour. IB seemed to have much more reliable data in the last hour when I switched to it, but still problems. Did any data providers hold up today?
PATS through GHCO was ok. Wasn't watching IB. eSignal was great most of the day, through several reports (European), but hung at 10 am EST.
