30 min after 15:30: 1.01x the tape's own vol, 17 days

These are the sessions in the free archive that carried S&P 500 rebalance at the close or Nasdaq-100 rebalance at the close or Russell reconstitution at the close or MSCI review effective at the close. Each opens the full minute-by-minute replay in the terminal: dealer gamma, the zero-gamma flip, the walls, the event's minute marked on the scrubber. The measured line above reads the same window on every one of these days against the same window on every other archived day: range over the window / (trailing 30-min move x sqrt(minutes)), mean on event days over mean on other days. The move column is the signed change in index points over 30 min after 15:30 and is filled for the most recent days the measurement carries; nothing here is a forecast.

Times are ET. Prints are the release's own numbers where the calendar has them: actual, forecast and prior. The book line, where present, comes from the dealer levels per minute of every archived session. See the Terms.
