What the positioning says

●Bullish positioning: only 0.49 puts per call outstanding.
●Call wall at $120 (4k contracts), 24% above spot — the upside strike the crowd is already parked on; often acts as near-term resistance.
●Put wall at $90 (2k contracts), 7% below spot — the hedge floor; often acts as support.
●Deep-OTM call OI is 3.5× deep-OTM put OI — speculative upside positioning dominates the tails.
