●Call wall at $10 (336k contracts), 256% above spot — the upside strike the crowd is already parked on; often acts as near-term resistance.
●Put wall at $2 (45k contracts), 29% below spot — the hedge floor; often acts as support.
●Deep-OTM call OI is 22.3× deep-OTM put OI — speculative upside positioning dominates the tails.
