🧩 Institutional Footprints on Option Charts
Retail traders can spot institutional footprints by:

Large ATM Straddle positions

IV divergence in option chain

Open Interest buildup without price movement (Smart money quietly entering)

Options being written at key support/resistance zones

Example:

If Bank Nifty is consolidating near a resistance and suddenly 2 lakh OI is built up in 50 point OTM Calls with low IV – this may be Call writing by institutions expecting price rejection.
