Watch next session: Any uptick in put volume at $170–$176 strikes (confirming bearish premium demand); Large trades or OI change at $170 CALL (37,775 OI) or $176 PUT (10,825 OI) that shift dealer hedge posture

Net premium: -$50.4M bearish

P/C volume ratio: 1.30 — put-volume dominant (today's trading leaned toward puts)

P/C OI ratio: 0.69 — OI still shows a call-weighted structural book (more call OI than put OI)

Call additions: Large multi-expiry call OI concentrated at $170 (37,775 OI) and higher-strike clusters $180/$184/$188 (notably $188: 4,595 OI). These call walls suggest prior institutional call selling/positioning at and above $170–$188.

Put additions: Active put volume today (P/C vol 1.30) suggests institutions were net buyers of near-term downside protection into the 4/10 and 4/17 expiries. Largest put OI clusters sit lower ($160: 4,279 OI; $164: 3,199 OI; $176: 1,927 OI), indicating protection accumulates below and near spot.

GEX/DEX consistency: Mixed but consistent with pinning: Total GEX +$21.3M and DEX +20.5M shares indicate dealers are long gamma (pinning) around the $172 flip while flow is net premium-negative—put purchases compress dealer hedges toward the gamma flip.

OI clusters: $170 call OI (37,775) is the dominant near-term concentration and will act as a magnet/wall around $170–$172 when combined with max pain; secondary call clusters at $180 (5,751 OI) and $188 (4,595 OI) create overhead resistance within the ±10% band. Put clusters are concentrated at $160 (4,279 OI) and $164 (3,199 OI), providing support zones below spot.

Hedging evidence: Evidence of short-term protective activity: elevated put volume and negative net premium indicate buying of puts or put spreads (protective/hedge demand). No clear large-scale collar structures visible in the snapshot; the bulk of long-term call OI suggests previous bullish positioning being protected by near-term puts.

Max pain context: Max pain for the nearest expiries is $169 (4/10) → $172 (4/17) → $176 (4/24). With spot $173.41 above MP and the gamma flip at ~$172, dealer hedging is likely to exert pinning pressure toward the $169–$172 band over the upcoming expiries.
