What the positioning says

●Defensive positioning: 1.19 puts outstanding per call — holders are hedging rather than selling.
●Call wall at $2,000 (5k contracts), 18% above spot — the upside strike the crowd is already parked on; often acts as near-term resistance.
●Put wall at $1,600 (4k contracts), 6% below spot — the hedge floor; often acts as support.
