Fast Stochastic measures the same range position as the Stochastic but with less smoothing, so it turns sooner. This page reports what it actually read on Bitcoin 10-minute charts — not what it is supposed to do, but the distribution of 9,993 recorded values over the last 90 days.
| Series | Median | Middle half | 5th / 95th | Full range |
|---|---|---|---|---|
| %K | 52.72 | 28.02 – 76.15 | 5.94 / 94.31 | 0 – 100.00 |
| %D | 52.69 | 29.42 – 74.77 | 10.65 / 90.23 | 0.7473 – 99.99 |
The median is the middle reading, so a single unusual session cannot drag it. The middle half is where Fast Stochastic sat on half of all bars — the range you should expect to see most of the time on this chart.
How often it reaches the levels people watch
| Reading | Bars | Share |
|---|---|---|
| Above 80 | 2,042 | 20.4% |
| Between 20 and 80 | 6,224 | 62.3% |
| Below 20 | 1,727 | 17.3% |
Fast Stochastic spent 62% of its time between 20 and 80 on this chart. A reading beyond 80 appeared about once every 5 bars, and below 20 about once every 6. How rare a signal is matters as much as what it says.

How this was measured
Every 10-minute bar of Bitcoin recorded in the last 90 days was read, and the values grouped without smoothing or filtering. Series with fewer than 400 readings are omitted rather than shown on thin evidence. These are recorded values, not predictions.
