Why Portfolio Guardian

Built for decision context, not recommendations.

Three clear signal states

Every ticker carries one of three structural states: Permission Granted, Stalking, or Ignore, based on whether it has validated a historically significant institutional price level.

Cohort-backed analysis

See historical win rates, death risk, and median ROI for tickers in similar structural positions. Not a single indicator, but a full cohort classification with years of data behind it.

Institutional gate levels

Guardian Pro surfaces the specific historical institutional price levels behind each validated ticker, including base gates, pullback gates, and claims progress through the structural window.

Sentinel alerts

Add tickers to your watchlist and Sentinel notifies you the moment a structural state changes, so you stay informed without watching the app constantly.

Discover feed

Browse a curated feed of tickers with notable structural setups, filtered by cohort quality and bucketed by recency. Idea generation without the noise.

Audit reports

For validated tickers, Guardian Pro unlocks a full structural audit report: the institutional level, execution window timeline, claims progress, and complete cohort data.
