I just found out about Marketsound at the CME. I thought the eminis were electronically traded. Are they also traded in a pit? The commentator is calling off trades. Is she just reading a tape like we are? If so, whats the point?
If I remember correctly the marketsounds site uses a computer voice to say the prices. When her voice gets louder it means volume has increased. It's just based on the same t&s of the emini's that are available to you...they are not traded in a pit. If you want a real squawk box check out los.net or realtimefutures.com
