How to Track FII Flows — 21 Jun 2026

Where to Find FII DII Data

How to Read FII Flow Data Correctly

The single biggest mistake in reading FII data: looking at one day. A Rs 5,000 crore sell day looks dramatic. But it might be followed by three Rs 2,000 crore buy days. The signal is in the cumulative 20-day flow, not the daily print. Track: (1) 20-day cumulative net flow in rupees, (2) number of positive vs negative days in that window, (3) streak length (consecutive buy or sell days), and (4) whether the signal is accelerating or decelerating. A 20-day sell of Rs 20,000 Cr that was Rs 30,000 Cr a week ago is actually improving, even though the headline number is negative.

FII Data Sources: What Each One Tells You

NSE and BSE publish provisional cash equity segment FII/DII data daily. This is the most widely quoted figure. But FIIs also operate in the derivatives segment (index futures, stock futures, index options). The F&O data tells you about hedging activity. When FIIs are net sellers in cash AND net short in index futures, conviction is high. When they are net sellers in cash but net long in futures, the selling may be tactical rather than strategic. Tracking both segments provides a fuller picture than the cash data alone.
