I asked the most basic questions and some people tease me; that's fine. Better to get responses quickly here than flip through websites, etc. A few more ... 1) right now, the most active contract for daytrading is 3/03 NQ, (NQ'H) right? I saw charts for both December and March and March seems to have more volume. 2) On IB, (I'm just learning how to use the TWS), there's CME and GLO(bex) for routing. Which one should I use for routing NQ orders? Depends on what hours? I want to trade only the most liquid and active hours.
