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 80 56 times and left it 56 times, with a median stay of 1 minutes and a longest stay of 13 minutes beginning at 18:45 ET. Below 20 there were 67 visits, a median of 3 minutes and a longest of 23 minutes.

What this is and is not
This is a record of where one indicator sat during one completed session. It is not a forecast, and it makes no claim that any reading preceded a move. Whether crossing 80 tends to be followed by a larger move is a separate question, measured separately.
How this was measured
Every 1m bar recorded for SPY on Thursday, August 20, 2026 — 871 bars from 04:01 to 20:00 ET — was classified by its Fast Stochastic reading. A visit is an unbroken run of consecutive bars in the same band. The session was complete before this page was built.
