FII & DII Data

FII (Foreign Institutional Investors): Entities like hedge funds, foreign pension funds, and investment banks that invest capital from outside the country. They often trade based on global macro conditions and risk appetite.

DII (Domestic Institutional Investors): Large local entities like mutual funds, insurance companies, and banks. They are often "steadier" hands, providing essential liquidity when FIIs pull capital out.

• The "Net" Effect: Look at the net daily buying/selling figure. If FIIs are heavy net sellers while DIIs are net buyers, the market may stay range-bound as domestic liquidity absorbs the foreign outflow.
• Trend is King: Don't react to a single day of data. Look for a 5-day or 20-day moving average of their net activity to identify a sustained trend in institutional sentiment.
• Divergence as Signal: If the index is hitting new highs but FIIs are consistently selling, it suggests that the rally is being propped up by retail or local sentiment and is fundamentally fragile.

Institutional data is a powerful confirmation tool. When your technical setup (e.g., a breakout) aligns with net institutional *buying*, the probability of a successful trade increases exponentially. When they conflict, the trade is significantly higher risk.
