Educational reference. Measured from 16 recorded 15 minute sessions of MES (Micro E mini S&P 500), September 4 to October 21, 2026. Updated as each new session is recorded.
In a typical session the 15 minute RSI on MES spends 9.9% of its time above 70, 82.0% between 30 and 70 and 8.1% below 30. It enters the upper zone about 1.5 separate times per session and the lower zone about 2.
The most time above 70 was on September 21, 2026 (56.5% of the session). The most time below 30 was on October 14, 2026 (32.6%).
Over the last 5 sessions the RSI spent 5.7% of its time above 70 and 12.9% below 30 — less time in the upper zone than its 16 session average of 9.9%.
RSI compares the size of recent gains with recent losses, so a reading above 70 says buying has dominated the last 14 bars — not that price is high. A long stay above 70 is a market trending up, which is the opposite of the reversal the word 'overbought' suggests.
A brief excursion above 70 that resolves in minutes is noise on this timeframe. A sustained one is the signature of a trend that is still running, and selling into it is how traders get run over.
