ATR % — Average True Range as a share of price
What it measures¶
ATR % is the Average True Range — the typical daily span of the price over 14 sessions, gaps included — divided by the latest close. It turns ATR's price units into a percentage, so a share priced at 20 and one priced at 2,000 can be compared: an ATR % of 3% means the price typically spans about 3% of itself in a day.
Why it is on the page¶
It is the form of volatility comparable across shares. The Price & timing strip's Volatility tile ranks it against the share's own last 252 sessions as a percentile and describes it — it never votes, because volatility has no direction.
Thresholds, their source and the population they were fitted on¶
ATR % has no fixed zones: what is normal differs between a utility and a young technology company. The strip judges it only against the share's own year:
| Percentile of the share's own year | What it describes |
|---|---|
| low | moving less than on most of its past year's days |
| middle | about as much as usual |
| high | more than on most of its past year's days |
- Source: Wilder (1978) for ATR; the percentile form follows the way options traders rank implied volatility.
- Fitted on: no population — a description of the share's own history.
- Evidence grade: not graded.
A worked example¶
On daily bars to 23 October 2026: Honeywell International 2.4% (66th percentile of its year), Apple 1.8% (12th percentile). As the Technical page showed it on 9 August 2026, Celestica read 8.33% — a share that moves a great deal, which any position size has to respect.
What “No verdict” means here¶
ATR % carries no verdict and no vote. It reads insufficient data until 15 daily bars are stored; the percentile needs 252 sessions and says so when they are missing.
What the verdict is and is not¶
The figure describes how much the price has been moving relative to itself. It is not a forecast of direction and not an instruction to trade the shares.
