Best insider tracker
The best insider trading (Form 4) trackers
For tracking insider trades, Brief Equity is the overall pick. The Form 4 trades for every ticker on your watchlists land in the Insiders tab of its feed, each labelled Bought, Sold, Received as pay, Exercised or Converted, with a filter for transaction and owner type. When you want every ticker, the market-wide Insiders stream on the Markets page runs across the whole market with the same filters. The trades sit beside news from 16 outlets, press releases, earnings-call transcripts, SEC filings and analyst ratings for the same stocks, next to a notebook for every stock and your own DCF and EV/EBITDA models. It is one plan, after a 10-day free trial with no card. For free screening of insider filings, OpenInsider lists cluster buys and top officer purchases, with no price or account on its pages (as of October 2026). For the source documents, SEC EDGAR is where insiders file their Forms 3, 4 and 5.

The pick for each use case
Insider trades for your watchlists, and for every ticker
Best pick: Brief Equity
The Insiders tab of the feed lists the Form 4 trades for every ticker on your watchlists, each labelled Bought, Sold, Received as pay, Exercised or Converted, with a filter for transaction and owner type and a count beside each one you tick. That view follows your watchlists by default, and the market-wide Insiders stream on the Markets page covers every ticker, with the same filters. The Latest tab merges the trades with news, press releases, earnings-call transcripts, SEC filings and analyst ratings for the same stocks, and a notebook for every stock sits beside them.
Free screening of insider filings
Pick for this job: OpenInsider
A screener of SEC Form 4 filings, with ready-made screens such as Latest Cluster Buys and Top Officer Purchases for today, the past week or the past month, and filters for filing and trade date, transaction code, insider title, industry and trade value. Its filing tables link each filing date to the filing on sec.gov. Its pages show no price and ask for no account (as of October 2026).
The source documents: Forms 3, 4 and 5

Who Brief Equity is for
It is built for…
- Investors who read insider buying as one signal among the news and filings for the companies they follow.
- Watchlist-driven researchers who want Form 4 trades gathered for every ticker they track.
- Note-takers who write a meaningful insider trade into the thesis for that stock.
- Readers who scan insider trades across every ticker in the market-wide Insiders stream.
The Brief Equity angle: insiders in context
Brief Equity treats Form 4s as one stream in the research feed. The Insiders tab lists the trades for every ticker on your watchlists, each labelled Bought, Sold, Received as pay, Exercised or Converted, and the Latest tab merges them with news, press releases, earnings-call transcripts, SEC filings and analyst ratings in one timeline, so a CFO purchase shows up beside the earnings call it followed.
The Insiders tab has its own filter for transaction and owner type, with a count beside each one you tick, so you can hide the routine noise and keep the trades you want to see. The feed follows your context: across all your watchlists at once, narrowed to a single list, or scoped to one ticker on its stock page and in the right-rail summary.
From there the work continues in the same place. Write a trade worth remembering into that stock's notebook: a true notebook, a full editor with headings, tables, checklists and callouts, in chapters and pages, beside your own DCF and EV/EBITDA models. A passage from an earnings call or a press release saves into the same notebook, with a link back to the source.
Your watchlists first, the whole market when you ask
Brief Equity's feed follows your watchlists by default, because an insider trade reads best next to everything else you know about the company. The market-wide Insiders stream on the Markets page covers the rest: it runs the same stream across every ticker, with the filters you already know.
So one workspace covers both habits: watching the companies you follow, and scanning the whole market for insider buying in names you do not track yet. Add a name worth a closer look to a watchlist, and its trades join your feed beside its news, filings and transcripts.
Where the filings come from
Every insider trade starts as a filing on SEC EDGAR. Officers, directors and holders of more than 10% of a class of shares report most of their trades to the SEC within two business days on Forms 3, 4 or 5, and EDGAR's Latest Filings page can be narrowed to those ownership filings (as of October 2026).
Brief Equity's insider trades come from those same EDGAR filings, read into your feed beside the rest of the news for each stock and labelled by what the insider did, so a purchase on the market stands apart from pay awards and option exercises.

Frequently asked questions
- What is the best insider trading tracker?
- Brief Equity is the overall pick: the Insiders tab of its feed follows the tickers on your watchlists, and the market-wide Insiders stream on the Markets page covers every ticker. For free screening of insider filings, OpenInsider. For the source documents, SEC EDGAR. For superinvestors who file as insiders, Dataroma.
- How does Brief Equity show insider trades?
- As one tab of the feed for every ticker on your watchlists, each trade labelled Bought, Sold, Received as pay, Exercised or Converted. The Insiders tab filters by transaction and owner type, the Latest tab merges insider trades with news, press releases, transcripts, filings and analyst ratings, and anything notable can go into the notebook for that stock.
- Can I see insider trades across the whole market in Brief Equity?
- Yes. The feed follows your watchlists by default, and the market-wide Insiders stream on the Markets page shows insider trades for every ticker, with the same filters.
- Is OpenInsider free?
- Its pages show no price or plan and ask for no account: the screener, the cluster-buy screen and the top-purchase lists all open to anyone (as of October 2026).
- How quickly do Form 4 filings become public?
- Insiders report most of their trades to the SEC within two business days. The filing then appears on SEC EDGAR, whose Latest Filings page lists the most recent filings for the current filing day; filings may be made Monday to Friday, except federal holidays (as of October 2026). Brief Equity's insider trades come from those EDGAR filings.
- What is a cluster buy?
- Several insiders at the same company buying within a short window, which many investors read as a lead worth a closer look. In Brief Equity, filter a stock's Insiders tab to purchases and its buys sit side by side; in the market-wide Insiders stream, the same filter keeps the purchases across every ticker. Add the stock to a watchlist and its next insider buys land in your feed.
