Near-expiry F&O symbols with balanced PCR (no extreme bias) and rising OI — primed for pin-gravity moves toward max_pain. Trader reads the max_pain column in the result row to decide direction: spot above max_pain → short bias as pin pulls down; spot below max_pain → long bias as pin pulls up. Tightest pin pressure in the final 3 days. Same-day close intraday.
*Price > max pain 1.05 near expiry = pin-back risk.** Options writers (institutions) profit when price gravitates toward max pain on expiry. When price is significantly above max pain with < 8 days to go, the squeeze back down is statistically likely.
max_pain > 0 + price > max_pain * 1.05 + 0 < expiry_days < 8 + PCR < 0.75 (call-heavy = sellers leaning bearish) + RSI 40–72 + change_pct > 0.
