What the positioning says

●Bullish positioning: only 0.66 puts per call outstanding.
●Call wall at $100 (19k contracts), 19% above spot — the upside strike the crowd is already parked on; often acts as near-term resistance.
●Put wall at $80 (23k contracts), 5% below spot — the hedge floor; often acts as support.
●Deep-OTM call OI is 5.9× deep-OTM put OI — speculative upside positioning dominates the tails.
