What is FII and DII activity?
FIIs (foreign institutional investors, officially FPIs, foreign portfolio investors) are overseas funds registered with SEBI to invest in Indian markets. DIIs (domestic institutional investors) are Indian mutual funds, insurance companies, banks and pension funds. Together they own a large share of India's listed market, so their daily net flows are among the most-watched numbers in Indian markets. The exchanges publish provisional cash-market figures every evening.
Formula
Net flow (₹ Cr) = gross purchases − gross sales, cash market, for the day

How to read it
- Sustained FII selling alongside DII buying has been the typical pattern in recent years. SIP inflows give DIIs a steady bid.
- The combined picture matters more than one day: a streak of FII buying often coincides with rupee strength and large-cap rallies.
- The daily figures are provisional; NSDL publishes final FPI data separately, and the two can differ.
Common mistakes
- Treating one day's FII number as a signal. Daily flows are noisy and include block deals, index rebalancing and arbitrage.
