Educational reference. Measured from 92 recorded 15m bars of ES (E-mini S&P 500) on Monday, September 14, 2026.
Fast Stochastics %K crossed above 80 5 separate times during the session, and the typical visit lasted 30 minutes. Across the whole session it sat above 80 for 14.1% of the time, between 20 and 80 for 55.4%, and below 20 for 30.4%.
| Band | Share of session | Bars | Separate visits | Median visit | Longest visit | |
|---|---|---|---|---|---|---|
| Above 80 | 14.1% | 13 | 5 | 30 min | 90 min | |
| Between 20 and 80 | 55.4% | 51 | 13 | 30 min | 195 min | |
| Below 20 | 30.4% | 28 | 9 | 30 min | 120 min |
The fast line is the unsmoothed version of the same range calculation, so it reaches the extremes far more often than the smoothed %K and leaves them sooner.
Here the reading entered overbought territory 5 times, with a median stay of 30 minutes and a longest of 90. The gap between this page's visit count and the smoothed Stochastics page for the same session is a direct measure of how much the smoothing removes.
