I acknowledge that a shared observation of the oscillating nature of the Emini's trading range - volatility isn't useful to some traders but is to specific traders.
here's what it tells me that midnight cst the market is trading in a 3 point range. from there the price range expands pretty good until regular session open "lot's of money to be made pre open. from open it's pretty much expanded out noon cst. the chart is very accurate in the portrayal of the story i just told. the average monthly range seems to about 12 points on average per day which includes the contraction so really the up down range is about 25 points total. half of which is in the morning sessions and half from noon to midnight.
