What the positioning says

●Defensive positioning: 2.16 puts outstanding per call — holders are hedging rather than selling.
●Call wall at $50 (3k contracts), 35% above spot — the upside strike the crowd is already parked on; often acts as near-term resistance.
●Put wall at $35 (15k contracts), 6% below spot — the hedge floor; often acts as support.
