What problem does it solve?

This Skill helps you quickly understand whether a market move is broad-based or narrow by summarizing advance-decline behavior, participation, and average price movement.

Core Features & Use Cases

  • Market Breadth Snapshot: Reviews daily counts of advancing, declining, and unchanged stocks alongside active issues and average return.
  • Sentiment Context: Helps distinguish bullish, bearish, and mixed market conditions from raw breadth data.
  • Use Case: An operator can check whether a rally is supported by many stocks or driven by a small subset of names before making a trading or research decision.

FAQPage Schema
What is market breadth analysis and how does it measure stock participation?

Market breadth analysis measures advance-decline balance and stock participation to determine if a market move is broad-based or narrow. It uses daily counts of advancing, declining, and unchanged issues alongside active listings to evaluate sentiment.

How do I check if a stock rally is broad-based or driven by a few names?

To check if a rally is broad-based, analyze market breadth data over a selected number of days. Compare advancing issues against declining ones and review average price movements to see if participation is broad, narrow, or diverging from the trend.

Can I use market breadth scans for both US and CN markets?

Yes, market breadth scans apply to both US and CN markets. You select the market and a date range, then the analysis requires daily counts of advances, declines, unchanged issues, active listings, average return, and standard deviation to measure sentiment.

What data inputs do I need to measure advance-decline balance and market sentiment?

To measure advance-decline balance and market sentiment, you need daily counts of advancing, declining, and unchanged stocks, active listings, average return, standard deviation, and advance rate over your selected scan period.

How does market breadth data identify bullish or bearish divergence?

Market breadth data identifies divergence by comparing the breadth trend against overall market movement. If a market rally shows narrow participation with declining advance rates, it signals a bearish divergence, whereas broad participation confirms bullish sentiment.

When should I not rely on market breadth for trading decisions?

You should not rely on market breadth alone when daily counts of active listings are incomplete or when the selected scan period is too short to establish a meaningful advance-decline trend, as this limits the accuracy of divergence and sentiment checks.
