# Insider trading summary

`GET /api/insider-transactions/summary`

![Stock](https://img.shields.io/badge/Stock-f97316) ![Pro](https://img.shields.io/badge/Pro-8b5cf6)

Returns aggregated insider trading statistics for the last 3, 6, and 12 months.
Only includes significant open-market trades (purchase and sale codes P/S) by officers and directors.
Transactions are deduplicated across co-owners — each physical trade counted once, prioritizing the most senior filer (officer > director > 10% owner).
Excludes trades with price >= $100,000 (SEC data entry errors) and Form 5 amendments when a Form 4 exists for the same trade.

`uniqueBuyers` and `uniqueSellers` count distinct insiders — cluster buying (multiple insiders buying) is a stronger signal than one person buying repeatedly.
