Quote from sammybea:
I am the first one to say "duh, its market conditions" but I have def noticed its far more volatile on Globex. Going from point A to point B is no longer that smooth. It might go from point A to point B and back to Point A several times within seconds before going to the next level.
Exactly. There's just more "noise" on it, i.e. a 10-15 point "fuzzy zone" around its current price. The larger swings probably are down to the Dow being more volatile.
