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

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.
