Relative Strength Index measures where price sits within its own recent gains and losses, on a 0–100 scale. This page reports what it actually read on E-mini Dow 5-minute charts — not what it is supposed to do, but the distribution of 17,678 recorded values over the last 90 days.
| Series | Median | Middle half | 5th / 95th | Full range |
|---|---|---|---|---|
| Relative Strength Index | 50.41 | 42.49 – 58.54 | 30.49 / 69.78 | 8.25 – 91.21 |
| Avg | 49.64 | 43.06 – 55.86 | 33.56 / 66.82 | 20.35 – 76.67 |
The median is the middle reading, so a single unusual session cannot drag it. The middle half is where Relative Strength Index 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 70 | 850 | 4.8% |

How this was measured
Every 5-minute bar of E-mini Dow 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 forecasts.
