The live level, today's change, and a plain-English signal are shown at the top of this page in the headline indices section, refreshing automatically through the trading day.

Option trading means buying or selling the right — not the obligation — to trade an index or stock at a fixed price by a certain date. Nifty 50 options, with weekly expiry every Tuesday, are the world's most actively traded derivatives contract by volume.

These figures show whether Foreign and Domestic Institutional Investors were net buyers or net sellers that day, across both cash and derivatives segments — we show both since they often tell different stories.

Index prices refresh roughly every 15 seconds during market hours, Nifty 50 stock data about once a minute, and FII/DII figures every 30 minutes as official numbers land.

No. NSE Trends shows live market data and technical context for informational purposes only. Nothing here is a recommendation to buy or sell any security, index derivative, or option contract. Please do your own research or consult a registered financial advisor.
