Definitions
In plain terms
It prevents a narrow intrabar high-low span from hiding a large jump between the prior close and the new bar.
Technical
The contract must declare current high and low, previous-close basis, first-bar behavior, units, adjustment consistency, and missing observations.
Scope
It measures observed envelope size, not the unobserved path traveled inside the bar or future direction.
Examples
- A reviewer traces Gap-Aware Range Measurement from aligned inputs through its first-ready row and edge cases before accepting a displayed value.
Common misconceptions
- It measures observed envelope size, not the unobserved path traveled inside the bar or future direction.

Evidence and governance
- True Range TA-Lib · first party technical publication
Supports: preferred label, short definition, technical definition
Limits: TA-Lib leaves the first row unavailable; the local D07 contract explicitly uses a high-low fallback.
