In plain terms
Zero trading volume can be a real value for an expected interval, while a missing volume means the system does not know the value.
Technical
Validity requires domain rules, unit, measurement or aggregation path, and evidence that zero lies in the allowed domain and was not substituted for absence.
Scope
Never use zero as a universal placeholder for null or missing data.
Examples
- A governed dataset records valid zero explicitly and preserves the source context needed to interpret it.
Common misconceptions
- Valid Zero does not have one universal meaning or policy without its declared source, scope, and data contract.
