What the positioning says

●Defensive positioning: 1.86 puts outstanding per call — holders are hedging rather than selling.
●Call wall at $110 (355 contracts), 19% above spot — the upside strike the crowd is already parked on; often acts as near-term resistance.
●Put wall at $90 (1k contracts), 2% below spot — the hedge floor; often acts as support.
