Which insider trading tracker should you use?
By Konstantine Gugunava and Lucas Gvetadze, founders of OQRO. Published . Updated . 4 min read. Last reviewed .

The short answer
It depends on the job. SEC EDGAR is the free source of every Form 4; OpenInsider is a Form 4 screener; Quiver Quantitative and Unusual Whales list insider trades beside many other datasets; OQRO compares each insider purchase with the company's own record since 2006 and keeps planned sales apart. We make OQRO.
How was this comparison made?
We make OQRO, so this page is written by one of the products it compares. Statements about the others come from their own pages, listed under Sources with the date each was read: the Quiver Quantitative and Unusual Whales pages on 2 November 2026, the OpenInsider home page on 9 October 2026 (it did not load when we tried again on 2 November), and the SEC pages in October 2026. We did not subscribe to any paid plan or test anyone's data. Figures about insider trades come from OQRO's count of SEC Form 4 filings.
The trackers side by side
| Tracker | What its own page shows about insider trades | Price it lists |
|---|---|---|
| SEC EDGAR | Every Form 4 as filed, a full-text search of filings since 2001, and insider transactions data sets extracted from Forms 3, 4 and 5 since January 2006, updated each quarter | Free |
| OpenInsider | A Form 4 screener with filters for filing and trade dates (from the latest day to four years, or all dates), transaction codes, insider title, industry and trade size, and ready-made lists such as cluster buys and top purchases. Its footer says the data comes from sec.gov | No price on its home page as of 9 October 2026 |
| Quiver Quantitative | Insider trading listed among the live datasets of its free plan, beside Congress trading, government contracts, lobbying and many others | A free Visitor plan; Premium at $25.00 a month |
| Unusual Whales | Insider trade data listed among its tools, beside options flow and dark pool data | A free plan with everything delayed by two trading days; Retail Basic $50, Retail Pro $75 and Retail Max $120 a month |
| OQRO | SEC Forms 4 and 144 read about every five minutes on US business days, planned (Rule 10b5-1) sales kept apart, each purchase compared with the company's open-market trades since 2006, and the company's Congress trades, 13F holdings and contracts on the same page | Free, no card; only the AI features (OQRO Pro) are paid, $9.99 a month or $79.99 a year, no trial |
Which tracker fits which need?
To read one filing, or to check a figure any tracker shows, open it on EDGAR: the Form 4 is the authority and costs nothing. To screen many filings with filters you set yourself, OpenInsider's home page is built around that. To see insider trades next to unrelated datasets such as lobbying or app ratings, Quiver lists them on one platform; to follow them next to options flow, Unusual Whales is built around options. To see whether an insider's purchase is unusual for that company, and what members of Congress and large funds did in the same stock, that is the job OQRO is built for; its rare insider trades page lists the week's purchases and sales that stand out against each company's own record.
What should a tracker separate for you?
Most insider sales are not a decision to sell at that moment. Of the 64,127 open-market sales reported on Form 4 for trades made in 2025, 35,228, or 55%, were marked as made under a Rule 10b5-1 plan, a trading plan set up in advance; since 2023 the Form 4 has a box for that (SEC fact sheet). Purchases are rarer: 12,782 open-market purchases by 3,881 insiders at 1,697 companies, with a median purchase of about $27,600 (OQRO's yearly figures). A useful tracker keeps purchases (code P) and sales (code S) apart from grants, option exercises and tax withholding, and shows the plan box. How to read those codes is in the five-minute Form 4 guide.
How soon does a tracker show a Form 4?
The law sets the pace. Section 16(a) of the Securities Exchange Act requires an insider to file a Form 4 before the end of the second business day after the trade (15 U.S.C. 78p), so most insider trades are public within days, far sooner than Congress trades. A tracker then adds its own delay between the filing on EDGAR and the moment the trade appears on its site. OQRO reads the SEC feed about every five minutes on US business days; the Unusual Whales free plan is delayed by two trading days; the other pages we read do not state a delay. A Form 4 filed late arrives late everywhere.
Are insider trading trackers free?
The source is: EDGAR, its full-text search and the quarterly data sets cost nothing and need no account. OpenInsider lists no price on its home page, Quiver has a free Visitor plan, and Unusual Whales a free plan delayed by two trading days. OQRO is free as well, with no card: every insider, company and filing page is open, and only its AI features (OQRO Pro, $9.99 a month) are paid.
What this does not tell you
This page compares what each product says about itself. It does not measure how complete or accurate its data is, how fast it lists a new filing, or how it computes any extra figure such as returns after a purchase. A Form 4 is a disclosure: it says what an insider traded, not why, and a purchase is not a forecast. Any tracker, OQRO included, can misread a filing, so the Form 4 on EDGAR remains the authority. For a wider table that includes 13F and Congress data, see OQRO and other public-disclosure trackers.
