Day price range
Day range
What it is
The lowest and highest prices reached during the trading session. Gives a sense of intraday move amplitude — useful for assessing immediate volatility.
How to read it
A tight range signals a calm day, little disagreement on price. A wide range signals nervousness — event, news, or buying/selling pressure. Compare the day range to ATR to see if it's exceptional.
Common reference points
- Tight range — calm< 1% of price
- Normal range1 – 3% of price
- Wide range — activity> 3% of price
Orders of magnitude, not a rule: the same number does not mean the same thing from one sector to the next.
What it does not tell you
Range alone doesn't tell direction. Always look at where price closed within the range — close to the high = buying pressure, close to the low = selling pressure.
