WHY NO ACTIVE SIGNAL?
Score anatomy
No score is calculated because there is no qualifying purchase in the active window. Unavailable inputs are not treated as zero or as a bearish signal.
Why is there no score?
- No qualifying open-market purchase supplies cluster, size, role, recency or conviction inputs.
- Sales and other Form 4 activity remain visible as context and do not create a negative score.
Sales and other Form 4 activity are shown separately and do not create a negative buy signal. Absence of buying is not scored as bearish.
Purchase breadth, concentration & cluster buying
These modules activate when qualifying purchases enter the 180-day research window.
