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 70 27 times and left it 27 times, with a median stay of 1 minutes and a longest stay of 20 minutes beginning at 09:57 ET. Below 30 there were 6 visits, a median of 2 minutes and a longest of 4 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 70 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 13, 2026 — 858 bars from 04:01 to 20:00 ET — was classified by its Relative Strength Index reading. A visit is an unbroken run of consecutive bars in the same band. The session was complete before this page was built.
