Universe: the 100 largest US-listed stocks and ETFs by market cap / fund assets (list pinned July 2026, refreshed periodically). Prices are live - one year of daily bars per ticker. Signals: price vs SMA 10/20/50/100/200, the 50/200-day cross, RSI(14), stochastic %K(14,3), CCI(20), Williams %R(14), MACD(12,26,9) vs its signal line, and 10-day rate of change. Oscillators need threshold AND direction to fire - oversold and turning up is a buy, overbought and turning down is a sell; overbought alone in a steady uptrend stays neutral. The composite rating averages buy(+1)/neutral(0)/sell(-1) across all 12: Strong buy at +0.5 and above, Strong sell at -0.5 and below (standard screener bands). Technical signals describe recent price action only - they say nothing about valuation or fundamentals and are not investment advice.
