I've noticed prints on Time & Sales (T&S) in the CL contract of anywhere from 100-5000 contracts usually printed between the B/A. I watch the DOM and never see anywhere near this number bid or offered. I watch the DOM and T&S simultaneously and see these types of prints in T&S but never see them in the DOM. Are these prints outside of CME/NYMEX electronic or something? Why are they being printed as trades in T&S but don't show up in the DOM? What am I missing? Thanks.
