How this page is built

Index closes, sector indices, the trading-holiday list and the results calendar come from NSE; SENSEX from BSE; FII and DII cash flows from NSE's daily provisional data; mutual fund flows from AMFI's monthly report; options positioning, the straddle and moving averages from MarketCue's own capture of NSE option chains and 1-minute NIFTY data; global markets from exchange quotes; news from Economic Times, Mint, NDTV Profit, SEBI and the RBI. Every number is recomputed from those sources; the summary paragraph is written by AI from the figures on this page. The page describes the week and does not give views on what comes next.
