Insider activity signals

Unusual activity detected via statistical analysis against historical baselines
This screen detects unusual insider trading activity using statistical analysis against historical baselines.
Signals are generated by comparing current insider activity against a 5-year historical baseline using Z-scores. The analysis also considers whether trades come from routine traders (predictable patterns) or opportunistic traders (irregular timing). Companies flagged by both methods receive a higher confidence score.
