Paper trading only

An auditable algorithmic portfolio

See what it owns—and everything it is watching.

The algorithm scans a diversified large-cap universe once each trading day. It holds cash when few stocks qualify, opens positions only when a tested signal appears, and records every paper trade.

A daily-bar sanity check for the current rules, not a forecast.
