Who are FIIs and DIIs, and how do I check their buying/selling in FYERS?

FIIs are foreign institutions that invest in India. DIIs are Indian institutions such as mutual funds, insurers, and banks. Their net buying or selling shows if big money is coming into the market or moving out. This helps you read market mood and liquidity.

Why it matters

  • Institutions trade large amounts and can affect prices and liquidity.
  • When both buy, the tone is usually positive. When both sell, it is usually cautious.
  • If FIIs sell but DIIs buy, domestic money may cushion the market, though foreign money is still leaving.

  • Cash – Final is settled data with equity + debt and arrives with a delay.
  • Use Weekly or Monthly to judge the trend; event days (results, rebalances, policy) can make one-day numbers look unusual.
