FII/DII Flows and Index Options: What Matters?
How foreign and domestic institutional cash flow can bias Nifty — and limits of flow-following for option traders.
Flows vs Derivatives
FII/DII data reflects cash market buying/selling — correlated with index direction but lagging and revised. Options OI can lead or diverge when institutions hedge with derivatives.
Use flows as macro bias (risk-on vs risk-off), not tick signal. Intraday option entries still need chain confirmation.
Practical Use
On policy days, flows and VIX together frame volatility regime.
