What exactly is market breadth?
Breadth measures how many stocks participate in a move rather than where the index closed. If the Nifty rises while most of its constituents fall, a handful of large weights are doing the work — a narrow move that historically sustains less well than a broad one.
How do I check market breadth in India?
You read market breadth indicators for the NSE — the advance decline ratio and advance/decline line, the percentage of stocks above the 50-day and 200-day moving average, and new highs versus new lows — across an index such as the Nifty 50 or Nifty 500. IndexBreadth computes all of them for 134 universes so you do not have to.
What is the advance–decline ratio?
The advance–decline ratio divides advancing stocks by declining stocks in an index. Above 1 means more stocks are rising than falling — broad participation; below 1 warns that an index gain is carried by only a few names. It is one of the oldest and most reliable market breadth indicators. IndexBreadth shows the NSE advance–decline live — updated every hour through the session — free on every plan.
How is this different from a screener?
A screener answers "which stocks match these rules right now". Breadth answers "what is the market as a whole doing underneath the index" — and gives you that as a history you can chart, compare across universes and test against price.
What is the FII DII COT Index?
The FII DII COT Index reads institutional futures and options positioning against its own recent range, so an extreme in FII or DII positioning stands out at a glance. IndexBreadth shows it for FII, DII, Pro and Client participants next to market breadth, which helps you see whether big money agrees with what participation is saying.
Which universes are covered?
134 in total — 20 broad and size indices, 13 official sectorals, 10 thematic indices and 91 purpose-built sector universes, each with its own constituent-level breadth.
How often does the data update?
Every trading session. The NSE advance–decline updates through the session, hour by hour — as live as breadth gets — and is free on every plan. Other daily internals land after the close, and the full hourly timeframe is on the plans that include it.
Is this investment advice?
No. IndexBreadth is market-analytics software. Nothing on it is a recommendation to buy or sell any security, and it does not provide research or advisory services.
