InsiderTradingRadar

Tracking insider stock trades manually through the SEC's EDGAR database is tedious and error-prone, requiring investors to sift through thousands of Form 4 filings, most of which represent routine option exercises, tax withholding, or pre-planned sales. InsiderTradingRadar addresses this friction by automating the discovery of meaningful insider transactions—genuine open-market buys and sells that signal real trading decisions—while filtering out mechanical noise and delivering alerts within minutes of filing.

The service polls EDGAR continuously and claims a capture rate exceeding 99.9%, targeting the moment each relevant filing appears. It classifies transactions across 20 SEC codes, distinguishes between intentional insider moves and automatic ones (10b5-1 plans, tax-based withholding, compensation awards, gifts), and batches notifications for email delivery every 60 minutes. The product also identifies clusters of insiders trading the same direction within short timeframes, historically a stronger signal than single trades, and extends its tracking to Congressional stock disclosures—a valuable addition since legislators typically report trades weeks after execution.

What sets this product apart is transparency about results. The company publishes its full historical track record, including losses alongside wins, without cherry-picking. Open-market buys showed a 0.3% median return at 7 days with a 53.1% win rate across 902 transactions; cluster buys performed better at 0.5% median return with a 57.2% win rate. Every alert includes sample size and historical benchmarking, ensuring users understand the statistical weight behind each signal. The founder's decision to disclose failure rates and low-frequency events honestly differentiates this from competitors who tend to highlight only successful predictions.

The free tier includes real-time Form 4 alerts batched hourly, one alert rule monitoring a single ticker, 10b5-1 filtering, and historical context on every alert. The service operates on a freemium model with upgrade options available, though pricing details for paid tiers aren't specified publicly. Users can cancel at any time.

The core value proposition is elegant: don't reinvent EDGAR access (the data is free and public), but automate the labor of classification, filtering, and rapid delivery while providing honest performance data. For investors building rules around insider signals, that automation justifies the investment.
