About Nortis

Nortis is an alerting service for insider trading disclosures. When a company executive, director, or large shareholder trades stock in their own company, regulators require them to disclose it publicly — in the United States through an SEC Form 4 filing, and in the United Kingdom through an RNS announcement of PDMR dealings (UK coverage is coming soon). Nortis watches US disclosures for the stocks you follow, classifies each one by its transaction type, and sends the alert to your Telegram within minutes.

How the system works

1. You choose what to watch

Add tickers from our Markets screener or type any SEC-registered symbol — we resolve the company's official SEC identifier (CIK) automatically. Free accounts can watch 3 tickers; Pro accounts have no limit.

2. We poll the regulators

Every 15 minutes, our servers query the SEC EDGAR submissions API for new Form 4 filings on your watched companies. Requests are made server-side with a descriptive User-Agent and throttled well below the SEC's fair-access limits. Each filing's raw XML is parsed into structured data: insider name and role, transaction code, share count, price, total value, transaction date, and filing date.

3. We classify the transaction

Every filing is sorted by its official transaction code, so an open-market purchase is clearly separated from routine events such as stock awards, option exercises or shares withheld for tax. Each alert states plainly what happened — who traded, how many shares, at what price and on which date — and never gives buy or sell recommendations.

4. Cluster detection

When three or more distinct insiders at the same company transact within a 7-day window, Nortis flags the pattern as a cluster. Coordinated insider activity is widely followed by analysts as a sentiment signal — we surface it, you interpret it.

5. Delivery

The alert lands in your linked Telegram chat with the key facts, the transaction type, any cluster flag, and a direct link to the original filing on the regulator's website so you can always verify the source.

Data sources

  • SEC EDGAR (United States) — the U.S. Securities and Exchange Commission's public filing system. Form 4 insider disclosures are typically filed within two business days of the transaction. Nortis links every US alert back to the original EDGAR document.
  • London Stock Exchange RNS (United Kingdom) — PDMR (Persons Discharging Managerial Responsibilities) dealing announcements. UK alerts are labelled separately from SEC data. Note: UK coverage is coming soon and is not live yet.

What Nortis is not

Nortis is not an investment adviser, broker, or trading platform. We do not recommend buying or selling anything. We report and explain public regulatory data faster and more clearly than reading raw filings — every decision you make with that information is your own.
