Two groups have the biggest information edge in markets: C-suite executives and members of Congress. Both are legally required to disclose their personal trades. When both buy the same stock — with institutions moving in dark pools and unusual options bets confirming it — that's not noise. That's four independent sources pointing the same direction. We find it, score it, and send you the data. Free.
We cross-reference four independent sources of institutional activity. When they converge on the same ticker in the same week, the data speaks for itself.
A C-suite exec writes a personal check to buy their own company's stock at full market price. Not a grant. Not options. Real cash — reported to the SEC within 48 hours on Form 4. We monitor filings every 15 minutes and surface C-suite buys within 20 minutes of filing.
Institutions route large trades through private exchanges to avoid moving the price. Every print is legally required to be reported — public data, buried in regulatory filings. When a $1M+ block appears on the same ticker as an insider buy, that's two independent parties moving in the same direction.
When someone spends $100K+ on out-of-the-money calls with weeks until expiry — volume at 2× open interest — that's not hedging. That's a directional bet with real money. We scan options flow every 5 minutes and flag sweeps that align with insider and dark pool activity.
Under the STOCK Act, members of Congress must disclose trades within 45 days. We track every House and Senate purchase and flag when a senator or representative is buying the same ticker as a CEO. When four sources agree — that's a Insider Buy.
4 Insider Buys. 1 Sell Cluster. All from publicly disclosed filings — SEC EDGAR, STOCK Act, FINRA dark pool. Every entry links to the primary source. Informational only — always verify and do your own research.
Under the STOCK Act, every member of Congress must publicly disclose their personal stock trades within 45 days. We aggregate every House and Senate purchase and flag when a senator or rep buys the same ticker as a CEO — creating the rarest signal we track: the Insider Buy.
