Market Breadth Dashboard

The Market Overview is the top-of-funnel snapshot inside TradersLab, pulling the most decision-relevant market data into one place. Along the top sit the major broad-market gauges — the NYSE Composite (^NYA), the equal-weight S&P 500 (RSP), the equal-weight Nasdaq 100 (QQQE) and small caps (IWM) — each shown with its price level, daily percentage move and a trend-condition label such as Pullback or Correction. Equal-weight proxies are used deliberately so mega-cap concentration doesn't mask what the average stock is doing.

Beneath the headline indices, risk and sentiment tiles frame the macro backdrop: a credit spread gauge (SHY vs. HYG), the VIX measured against its 21-day moving average, and Bitcoin as a speculative-appetite proxy. A widening SHY/HYG spread flags risk-off conditions as an early defensive warning, while the VIX below its 21-day MA reads as a neutral-to-bullish backdrop.

The dashboard turns raw internals into readable signals. Market Sentiment reads daily advance/decline breadth; New Extremes counts new 21-day highs versus lows to show whether participation is expanding or deteriorating; Long-Term Health tracks the percentage of stocks above their 200-day average, where roughly 50% is a healthy broad uptrend and below 50% signals weakening. Breadth Momentum is a z-score-normalized read of the McClellan Oscillator and Summation Index — the McClellan Oscillator being the difference between the 19-day and 39-day EMAs of net advances — where a high positive value is a momentum thrust and a deep negative is oversold and washed-out.

Sector Strength counts how many of the 11 GICS sectors are positive: more than 7 signals broad strength and a higher-probability trend, while fewer than 4 signals narrow leadership and higher false-breakout risk. A full breadth engine sits behind these tiles — cumulative 52-week high/low lines, up/down volume, and a Percent of Stocks Above Key Moving Averages panel spanning the 5-, 10-, 21-, 50- and 200-day averages. On the 21 EMA, below 25% reads oversold and above 75% overbought.

The Global Daily Breadth section turns quantitative breadth into visuals — a sector-distribution bubble chart, an intraday GDB chart and a returns view — all toggleable across the S&P 500, Nasdaq 100, Russell 2000 and NYSE universes. Intraday GDB is the live, continuously updating version of the measure: where traditional breadth tools only report at the close, it refreshes throughout the session so you can watch internals evolve in real time.

A positive intraday reading signals broad upside participation and a more sustainable rally; a negative reading means decliners outweigh advancers and downside risk is rising. Because the same reading is computed for several indices at once, you can compare breadth across markets and watch for divergences — price rising while GDB falls warns of exhaustion, price falling while GDB improves hints at accumulation. A Daily Market Breadth Snapshot table repeats the reads (ADV, DECL, NET, new highs/lows and % above each moving average) for every market and sector, with clickable rows that open a mini price chart.

On top of the raw numbers, TradersLab layers an AI Insights read that interprets the market for you. On the Market Internals dashboard it generates a plain-English narrative — with an overall stance such as bullish, mixed or risk-off — that ties the day's cross-asset signals together: crude oil and the VIX, credit spreads (SHY vs. HYG), intermarket ratios like technology versus staples (XLK/XLP), and gold. Instead of leaving you to connect a dozen separate gauges, it spells out what they mean as a whole and points to the specific levels worth watching.

It distills each read into a few key tells — the one or two conditions most likely to decide the next move — and refreshes on demand as conditions change. The same AI Insights read is also available from the TLMM dashboard, so the interpretation sits right next to the breadth data it's drawn from.
