Why the visit count matters more than the percentage
A share of the session says how much time a reading spent in a band. It does not say whether that time came as one sustained stretch or as repeated brief excursions. Here the reading entered the zone above 25 3 times and left it 3 times, with a median stay of 130 minutes and a longest stay of 365 minutes beginning at 00:00 ET. Below 20 there were 6 visits, a median of 122 minutes and a longest of 225 minutes.

What this is and is not
This is a record of where one indicator sat during one completed session. It is not a prediction, and it makes no claim that any reading preceded a move. Whether crossing 25 tends to be followed by a larger move is a separate question, measured separately.
How this was measured
Every 5m bar recorded for ES on Tuesday, August 18, 2026 — 276 bars from 00:00 to 23:55 ET — was classified by its ADX reading. A visit is an unbroken run of consecutive bars in the same band. The session was complete before this page was built.
