How Nortis works
From filing to signal in four steps
We analyze
Each filing is classified by its transaction code, so routine events never look like real trades.
You receive
Important alerts arrive on your dashboard and Telegram with source links.
You stay informed
Routine events and stronger signals are separated clearly.
Signal language
Not every filing means the same thing.
The product separates real open-market trades from grants, tax withholding, option mechanics, and other routine disclosures.
Insider buying
Open-market purchases made with personal capital.
Insider selling
Sales are labelled with context instead of treated as automatic signals.
Cluster activity
Multiple insiders transacting in a short period are surfaced quickly.
Routine events
Tax withholding, grants, and awards are kept separate from true trades.
Trust layer
Public data, source-first.
Nortis is an information and research tool. Every alert links back to the original regulatory filing.
