How We Calculated This
When does a "trading day" start? We use the CME Globex convention. Each day starts at 5:00 PM Chicago time and runs until 5:00 PM the next day. So Sunday evening counts as Monday's session.
ETH (Extended Trading Hours): The full overnight + day session combined. Basically everything from open to close on Globex.
RTH (Regular Trading Hours): Just the US cash session, 9:30 AM to 4:14 PM Eastern. This is when most volume happens.
First Hour: 9:30 to 10:29 AM Eastern. The opening hour of the cash session, usually the most active period of the day.
Daily Range: The difference between the highest and lowest price of the day, in points.
Realized Volatility: How much price moved minute-by-minute, scaled up to an annual number. Higher = more movement. Shown as a percentage (e.g. 22% means high volatility).
Parkinson Volatility: Similar idea, but only uses each day's high and low price instead of every minute. Useful for comparing with realized vol.
Rotations: How many times price crossed back over the opening price during the day. More rotations = more back-and-forth, choppy action.
Trend-Like Day: The close was far from the open relative to the day's range (at least 50%). Price picked a direction and stuck with it.
Chop Day: The close was very close to the open relative to the range (25% or less). Price moved a lot but went nowhere.
Gap: The difference between today's open and yesterday's close. "Gap up" means we opened higher, "gap down" means lower, "flat" means roughly unchanged.
