Tab guide · Breadth
The Breadth tab is the central command panel for reading the overall health of the US equity market. It combines a historical heatmap of breadth metrics with live overlays, regime indicators, and a mini-chart strip.
Open the Breadth tab each morning. Scan the last few rows of the heatmap for colour — is the tape improving (more green), deteriorating (spreading red), or mixed? Check the Market Tone bar and the session pill, then look at the mini-charts for trend context.
Each column counts how many stocks make a significant price move over a specific lookback: 4%+ in a day, 20% in 5 days, 25% in a month, 13% in 34 days, and 25% in a quarter. The ratio column (up 4%÷ down 4%) gives a quick balance-of-power read. Above 1.5 = buyers dominating; below 0.67 = sellers in control.
The Market Tone bar summarises the regime — Bullish, Bearish, Mixed, or Caution — from breadth across all timeframes. The two gauges show what share of the universe is trading above their 50-day and 200-day moving averages. Below 40% on the 50-day gauge signals a broad correction.
