Premium = LTP × volume × lot size. More put premium is not automatically bullish or bearish — read with price, OI change and IV.

Limiting the window to strikes near ATM stops far out-of-the-money contracts from distorting the read.

Price ↑ + OI ↑ → possible fresh buying · price ↓ + OI ↑ → possible writing · price ↑ + OI ↓ → possible short covering · price ↓ + OI ↓ → possible long unwinding. Volume and IV change adjust the strength of evidence. Trader intent is never certain.

Expiry positioning shift: Bullish-leaning positioning in the current expiry also appears in later expiries (near 76, later 82).

Positioning (0–100) blends OI PCR (conventional reading) with net premium pressure for each expiry, using ±10 strikes.
