You’ll also need to buy the Rithmic data for it to work. It’s $40/mo if you only want CME. BUT it’s $100/mo if you also want CBOT, NYMEX, and COMEX. So far I like CBOT for being able to show me /YM (Dow Jones futures). However, after seeing what happened to oil futures recently, it might simply be best to stay on the main path with trading /MES.
