InsiderAct vs Quiver Quantitative: Insider Trading Tracker Comparison (2026)
Quiver Quantitative is a broad alternative-data platform where insider trades are one dataset among many. InsiderAct does one thing: it filters SEC Form 4 filings into scored insider buying signals. Here is how they compare, and when each makes sense.
Quick Answer
Quiver Quantitative is best if you want many alternative datasets, backtesters, and strategy tools in one subscription (Premium is listed at $25/month). InsiderAct is best if insider buying is your main trigger: it scores cluster buys, flags large purchases and dip buys, and explains why each signal qualified. Both use public SEC Form 4 data, so the difference is analysis, not source.

Quiver Quantitative: Best for Multi-Dataset Research
Quiver Quantitative collects many datasets into dashboards, and insider filings are one of them. Premium adds tools such as strategies, a stock screener, backtesters, a watchlist, data export, and an email of new filings and dataset updates. A separate API subscription is available for developers.
For an investor whose edge is insider buying specifically, the breadth is also the cost: the insider view is a dashboard rather than a ranked shortlist, and you do the pattern recognition yourself.

- ✓Strategies, backtesters, a screener, and data export on Premium
- ✓Free-to-browse dashboards and an iOS and Android app
- ✗Insider trading is one dashboard among many, not the product focus
