🎯 STRONG RANGE: Short Strangle / Iron Condor

Heavy OI walls: CE at 24,300 (13216K OI, +250%) and PE at 23,500 (6960K OI, +73%) since 25-Aug. Both sides loaded — high conviction 23,500–24,300 range play into expiry.

📐 RANGE: 23,500 – 24,300 (800 pts)

As expiry approaches, spot gravitates toward max pain. Watch for accelerating OI velocity as pin-risk increases.

Method	Strike	vs Spot	What it measures
Standard	24,200	+110	Raw OI payout matrix — flat probability across all strikes
Premium-weighted	24,300	+210	OI × premium weight — suppresses deep-OTM noise, amplifies near-money strikes
RND (Breeden-Litzenberger)	24,200	+110	Market-implied probability density (d²C/dK²) — skew-adjusted expiry magnet · RND computed from full strike chain

When all three converge → high-conviction pin level. When PW or RND diverge from Standard → deep-OTM positions distorting the raw number.

📊 PCR: 0.593 → BULLISH

PCR is FALLING. Falling PCR = PE unwinding or fresh CE writing = caution.

🔴 MAX VELOCITY: Today

Largest single-session OI addition on Today. Highest institutional conviction day — aggressive capping or floor defence. Cross-reference with that session's spot move.

Term Structure: Near-Week vs MONTHLY

Comparing Today (near) against Today (monthly). CONFIRMING = both tenors moving the same direction (conviction stacking across the term structure). DIVERGENT = tenors disagree — often a rollover/hedge unwind rather than fresh directional conviction. PARTIAL = only one tenor active. Agreement rate (excl. both-flat legs): 60.0% (6 confirm / 4 divergent / 0 partial / 0 flat)
