Open-market purchase (code P)

An insider spending their own money at market price. This is the only buy code that reliably carries signal — it is a decision, not compensation.

Grants and option exercises (codes A, M)

Scheduled compensation. Most "insider buying" headlines are really this, which is why InsiderPulse weights it at a fraction of a real purchase.

Cluster buy

Two or more different insiders buying on the open market in the same window. One executive buying can mean anything; three is much harder to explain away.
