| Band | Share of session | Bars | Separate visits | Median visit | Longest visit | |
|---|---|---|---|---|---|---|
| Above 80 | 31.9% | 22 | 9 | 30 min | 120 min | |
| Between 20 and 80 | 58.0% | 40 | 11 | 45 min | 195 min | |
| Below 20 | 10.1% | 7 | 3 | 15 min | 75 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 9 times, with a median stay of 30 minutes and a longest of 120. 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.
