OpenInsider Alternative: Free SEC Form 4 Tracker
Swiss-Quant (swiss-quant.ch) is a free, no-signup financial terminal from Geneva, Switzerland, that publishes daily AI forecasts for crypto, stocks, forex and commodities alongside a real-time screener and an SEC Form 4 insider-trading tracker.
If you are searching for an OpenInsider alternative or a “SEC insider trading tracker free”, this page explains what Swiss-Quant's SEC Insider Screener does, how it compares with OpenInsider, SecForm4, MarketBeat and Finviz, and where each tool is the better pick. Everything stated about Swiss-Quant can be checked on the screener page itself; competitor details come from their public sites in September 2026 and are marked not verified where we could not confirm them.
What the Swiss-Quant insider screener does
The screener automatically fetches and parses Form 4 filings from the SEC EDGAR database. Form 4 is the document every officer, director and 10%-plus shareholder must file within two business days of buying or selling their own company's stock. Swiss-Quant captures both purchases and sales, enriches each row with the current stock price so you can see post-transaction performance, and ranks filings by conviction signals such as transaction size and insider title.
- Buys only / Sells only — separate insider purchases (historically the more informative side) from routine selling.
- Large transactions (> $100K) — keep only filings where the insider moved more than $100,000.
- CEO / CFO only — C-suite filings, the ones with the deepest company knowledge.
- Post-filing performance — the stock's move since the transaction, computed from current quotes.
- Alerts — a daily digest of new filings goes to the Telegram channel at 09:00 CET; the server refreshes its EDGAR cache about every 50 minutes.
The screener needs no login and has no paid tier. It sits next to the rest of the terminal, so a filing can be checked against the same ticker's technical score on the screener or its AI forecast on the equity forecast page without leaving the site.

When to use which
Choose OpenInsider when you need the richest filter set, cluster-buy detection and a decade of history in one table. It is a mature, free, no-signup tool and Swiss-Quant does not claim to replace its screener depth.
Choose Swiss-Quant when you want a lighter screener that already answers “what happened to the stock after the insider bought?”, want a daily digest in Telegram, or want insider filings side by side with a technical screener, an options chain and daily AI forecasts, all without an account.
Choose Finviz if your workflow is already in the Finviz screener and you only need the latest officer trades. Choose MarketBeat or SecForm4 if you want e-mail alerts on specific insiders and do not mind creating an account or paying for them.
How to read Form 4 filings
Insiders sell for many reasons: diversification, taxes, house purchases, scheduled 10b5-1 plans. They buy on the open market for essentially one reason: they think the stock is cheap. That asymmetry is why most screeners, Swiss-Quant included, weight purchases more heavily. Signals that historically carried more information: purchases by the CEO or CFO, several insiders buying in the same window (cluster buying), and open-market purchases above $100,000 rather than option exercises or grants. Large, unusual selling by several executives at once can also matter, which is why the screener tracks both sides.
None of this is a trading rule. A filing tells you what an informed person did with their own money two days ago, not what the stock will do next week. Combine it with your own research, and read the risk disclaimer.
FAQ
Is the Swiss-Quant SEC insider screener really free?
Yes. The screener is free, has no account, no paywall and no feature tiers. It is funded by ads on the site and by the maker's own time.
How fresh is the insider data?
Filings are pulled from SEC EDGAR and the cache is refreshed roughly every 50 minutes on the server; a daily digest of new filings is posted to the Telegram channel at 09:00 CET. The SEC itself gives insiders two business days to file Form 4, so no tracker can show a trade before the insider reports it.
Does it cover both insider buys and sells?
Yes. Both purchases and sales are captured, with filters for buys only, sells only, transactions above $100,000 and CEO/CFO-only filings.
Is OpenInsider still the best tool for cluster buys?
OpenInsider's screener has more filter dimensions (cluster buys, 10b5-1 exclusion, ownership change) and a longer history, and it remains an excellent free tool. Swiss-Quant is a simpler screener that adds current price and post-transaction performance and lives inside a terminal with forecasts and a technical screener.
Is insider buying a reliable signal?
Academic studies have found that open-market insider purchases, especially by CEOs and CFOs and in clusters, have on average preceded above-market returns. That is a statistical tendency, not a guarantee; see the risk disclaimer before acting on any filing.
