Educational reference. Measured from 92 recorded 15m bars of ES (E-mini S&P 500) on Wednesday, September 16, 2026.
Fast Stochastics %K crossed above 80 6 separate times during the session, and the typical visit lasted 30 minutes. Across the whole session it sat above 80 for 25.0% of the time, between 20 and 80 for 67.4%, and below 20 for 7.6%.
| Band | Share of session | Bars | Separate visits | Median visit | Longest visit | |
|---|---|---|---|---|---|---|
| Above 80 | 25.0% | 23 | 6 | 30 min | 150 min | |
| Between 20 and 80 | 67.4% | 62 | 11 | 60 min | 180 min | |
| Below 20 | 7.6% | 7 | 5 | 15 min | 45 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 6 times, with a median stay of 30 minutes and a longest of 150. 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.
