AlphaYouBest Insider Trading Trackers Compared (2026)
Insider trading trackers compared side by side - SEC EDGAR, OpenInsider, Finviz, Barchart, Quiver and AlphaYou. What each covers, what it costs, and which ones separate real buys from grants.
OpenInsider is a free Form 4 screener. Finviz is the better pick if you want the filing shown next to a chart. AlphaYou and Quiver are the ones to look at if you want insider buys read alongside congress and 13F activity. The difference that decides most of it is whether a tool separates open-market purchases from grants, because a grant is not evidence of a cash purchase.
The Options Side by Side
Six tools cover US insider filings seriously. Coverage and pricing were checked in September 2026; prices change often, so treat the paid column as a starting point and confirm on each site before subscribing.
| Tool | What it covers | Free tier | Paid from | Best for |
|---|---|---|---|---|
| SEC EDGAR | Every Form 4, primary source | Full access, no signup | Free | Reading the original document |
| OpenInsider | US Form 4 only | Full access, no signup | Free | Filterable Form 4 tables |
| Finviz | Form 4 plus charts and fundamentals | Insider table free | $39.50 a month or $299.50 a year for Elite | Seeing the buy next to the chart |
| Barchart | Form 4 plus broad market data | Free with an account | $29.95 a month or $199.95 a year for Premier | Filtering large transaction lists |
| Quiver Quantitative | Insiders, congress, 13F, contracts, lobbying | Limited | About $25 a month, billed yearly | The widest alternative-data spread |
| AlphaYou | Insider Form 4, congress, 13F, contracts, influencers | Free forever | $29 a month or $199 a year | One feed across every filing type |
The 2-Day Clock Every Tool Shares
Insiders file under Section 16(a) within 2 business days of the trade, so no product on this list can show you a purchase before it is public. That window applies identically to a free site and a $39.50 a month one. What a tracker can compete on is how quickly it surfaces the filing once EDGAR publishes it, and how much context sits beside it. Any tool advertising that it beats the disclosure itself is describing something that does not exist.
Grants Are Not Buys
Use the SEC's transaction-code definitions. P includes open-market and private purchases, S includes sales, and A covers grants or awards. Read the footnotes to establish the transaction context and check the trading-plan disclosure. Do not rank every increase in ownership as a cash purchase.
What a Free Tier Actually Gets You
This category has unusually good free options, which is worth saying plainly. OpenInsider is free, needs no account, and offers transaction-code filters. EDGAR is the primary source and costs nothing. Between them you can cover insider monitoring properly if your routine is checking buys a few times a week. The paid tools are selling one of two things: breadth, meaning insider filings read next to congress and fund activity, or delivery, meaning an alert that reaches you instead of a dashboard you have to remember to open. Work out which of those you are buying, because neither is worth paying for if a free table already fits your routine.
Where AlphaYou Fits
AlphaYou reads insider Form 4s next to congressional disclosures, 13F fund positions, government contract awards and tracked influencer calls in one feed, on the logic that a cluster of insider buys means more when you can see a fund building the same position. Open-market purchases are separated from grants and private transactions rather than pooled into one count. The free plan stays free rather than expiring into a trial.
Where it is a weaker fit: OpenInsider offers a free Form 4 table, and Finviz pairs its free insider table with chart and company pages. We have not measured their notification speed against AlphaYou. If insider data alone is the job, the free tools do it well and we would rather say so.
FAQ
What is the best free insider trading tracker?
OpenInsider is a useful free option: it needs no account and covers US Form 4 filings. SEC EDGAR sits underneath it as the primary source.
Can any tracker show insider trades in real time?
No. Section 16(a) gives insiders 2 business days to file, so every tool draws from the same published filings. Trackers compete on how fast they surface a filing after it is public.
Why do the biggest insider buys often turn out to be grants?
Because transaction code A, an award, is compensation rather than a purchase, and many rankings pool it with code P, an open-market buy. Filter to P before reading any list.
Is a dedicated insider tool or a bundled one better?
Some dedicated tools provide free Form 4 tables. Bundled tools cost more but let you read an insider buy next to congress and 13F activity on the same stock, which is usually where the context sits.
