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.
