Insider activity signals

Available to Premium users
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.
