# InsiderAlpha

> AI-powered SEC insider trading intelligence platform. Tracks Form 4, Form 144 and 8-K filings in real time, scores insider buys with role + size + recency + cluster signals, and turns the result into a daily trading plan.

## What InsiderAlpha is

InsiderAlpha ingests every SEC Form 4 (insider transactions), Form 144 (planned sales by affiliates), and 8-K (material corporate event) filing as it is published, then exposes:

- Per-company pages with full insider transaction history, recent SEC filings, and AI-classified 8-K catalysts.
- Per-insider pages showing every reported trade, role at each issuer, performance track record, and cluster co-buyers.
- A daily, scored trading plan that filters for purchases ≥ $10K, valid liquidity, and high-confidence role × size × recency × cluster signals.
- 10b5-1 plan detection (pre-scheduled trades flagged separately so they don't pollute discretionary buy signals).
