PennySignal is a standalone alert service for penny stocks. It watches every insider transaction under $5/share, and the moment 2+ different insiders buy the same stock in the same short window, you get an alert — company, ticker, and insider count, sent the moment it happens.
Every alert this has ever sent is public, including the losers — nothing curated out after the fact.

By notification
The same alert, this time as a push notification through the ClusterSignal app.
An alert lands in your inbox the moment the pattern shows up — nothing to check, nothing to interpret.
Every insider transaction under $5/share, pulled daily from public filings.
2+ different insiders buy the same stock in the same window — that's a cluster.
You get the ticker and insider count — by email, app notification, or both.
Not a recommendation to follow, and not part of the alert itself — an example of the profit targets that performed best in testing, scaled by insider count.
| Insiders | Example target |
|---|---|
| 2 Insiders | +15% |
| 3 Insiders | +20% |
| 4+ Insiders | +25% |
Not a rule for any specific position — just what backtesting favored. Exit decisions, including whether and when, are the trader's own call.
The specific thresholds that decide what qualifies as a cluster.
Every alert this has ever sent is on the results page, including the losers — nothing curated out after the fact.
Everything is included in every plan — choose your commitment.
