The rule-based badge uses the methodology below. Component movements explain arithmetic price changes, not the badge assignment.
Based on price history. Inventory, supplier terms, and lead times are not included.
Eligibility requires 30 observations, available weekly and premium-average comparisons, prices no more than 4 calendar days old, and no latest movement flagged for review. Weekends and holidays count; this age rule does not establish that an exchange publication was missed.
An input-series movement greater than 10% since the preceding observation needs review. Exactly 10% is not flagged. A premium changing from zero to positive is flagged separately. Historical flags do not withhold the current signal.
Rules use unrounded values, in order: Buy when combined is below its 30-observation mean, its 7-observation direction is not Up, and dispersion is not High. Hold when combined is more than 2.5% above its 30-observation mean, or when 7-observation direction is Up, premium is above its 30-observation mean, and weekly combined change exceeds 0.8%. Otherwise Watch.
Weekly comparisons use the newest price on or before 7 calendar days before the latest date, no earlier than 10 days before it. No interpolation or carry-forward is used. Direction and dispersion definitions appear in Sources & methodology.
