What it does
Detect cluster buying for a company: periods where 3+ distinct insiders bought shares (Form 4 open-market purchases, code P) within a 14-day window, over a lookback of 7, 30 or 90 days (default 90). Returns clusterBuyingDetected, the strongest clusterWindow, a summary (totalValue is null when no purchase disclosed a price, and is a floor when unpricedPurchaseCount > 0) and the deduped purchases.
asOf and lookback state the date range covered; clusterBuyingDetected false means none in that range only.
