What is market breadth and how does it confirm price moves?

Market breadth measures whether advances, declines, and participation confirm or diverge from price moves. It uses advance-decline counts, flat issues, active stocks, average return, standard deviation, and advance ratio to reveal broad participation or narrow leadership.

How do I check daily market breadth and sentiment for CN and US equities?

To check daily market breadth, query the desired market and day range to return a breadth snapshot. Review the advance-decline counts and advance ratio to summarize whether participation is broad, weak, or diverging for CN and US equities.

Can I compare market breadth trends between the CN market and US market?

Yes, you can compare CN versus US market behavior. By configuring the market and day-range selection, you track breadth over multiple days and compare cross-market participation to identify divergent or confirming sentiment trends.
