About and limits
With a Finnhub key the score also includes company financials, earnings history and news headlines, and upcoming earnings are flagged. The news reading is a keyword count and the financials come from a free source that may be incomplete or delayed. The chart reading scores trend, momentum, RSI and range position of your saved price history; in a 40-year test it did not predict returns, so treat it as a description of the chart. The Second opinion is a separate model with a small tested edge. Neither knows about your taxes or goals, and none of this is financial advice. Holdings and the practice account stay on this device. Free data is delayed and rate-limited, so large lists refresh slowly. Alerts fire while the app is open; background push needs the small server.

Ranked by the Second opinion
About this screen
Screens a fixed list of well-known stocks and ETFs that are not on your watchlist and ranks them with the Second opinion, the model that showed a small, tested edge over 40 years. The chart reading is shown but only breaks ties, because it did not predict which stocks would do better. It is a screen, not a prediction.
