What the positioning says

●Bullish positioning: only 0.16 puts per call outstanding.
●Call wall at $75 (306 contracts), 3% above spot — the upside strike the crowd is already parked on; often acts as near-term resistance.
●Put wall at $45 (28 contracts), 38% below spot — the hedge floor; often acts as support.
●Deep-OTM call OI is 4.1× deep-OTM put OI — speculative upside positioning dominates the tails.
