Overview

The STOCKAN FII/DII Tracker aggregates and visualizes official institutional activity data published daily by NSE and BSE. It presents this data in a format designed for rapid decision-making — not spreadsheet archaeology.

Data Coverage

Cash Market Data

  • FII Net Buy/Sell (in ₹ Crores)
  • DII Net Buy/Sell (in ₹ Crores)
  • Gross purchases and gross sales for each category
  • Rolling 5-day, 10-day, and 20-day net flows

Derivatives Data

  • FII long and short positions in Index Futures
  • FII long/short ratio (the "FII sentiment index")
  • DII index futures positioning
  • FII activity in Stock Futures

Sector-Level Breakdown

  • Which sectors FIIs are accumulating vs distributing
  • Historical sector rotation patterns
  • Volume-weighted institutional activity by sector

Key Signals to Watch

1. The FII/DII Divergence Signal

When FIIs are net sellers and DIIs are strong net buyers, the market typically finds support faster than when both are selling. This divergence is a powerful indicator of near-term stability.

2. FII Futures Long/Short Ratio

This ratio — tracked daily — is one of the best leading indicators for NIFTY direction:

Ratio Signal
> 65% Long Strongly bullish — FIIs positioned for up move
50-65% Long Moderately bullish
40-50% Long Neutral
< 40% Long Bearish — FIIs net short

3. 5-Day Rolling FII Flow

A sustained 5-day FII buying streak of ₹3,000+ Crore total is historically associated with NIFTY gaining 1.5-3% in the following 2 weeks. Conversely, 5-day selling streaks of similar magnitude signal near-term weakness.

Interpreting the Dashboard

The tracker presents data in three views:

Today's View: Real-time (delayed) snapshot of today's flows with comparison to yesterday and the 5-day average.

Trend View: 30-day rolling chart of FII and DII flows, with NIFTY overlay. Spot the correlation visually.

Extreme Readings View: Days when FII buying or selling exceeded 2 standard deviations from the mean — historically significant events that often precede major moves.
