What the positioning says

●Call wall at $115 (3k contracts), 4% above spot — the upside strike the crowd is already parked on; often acts as near-term resistance.
●Put wall at $110 (3k contracts), 0% below spot — the hedge floor; often acts as support.
●Deep-OTM call OI is 2.1× deep-OTM put OI — speculative upside positioning dominates the tails.
●30-day ATM implied volatility is 20% — calm pricing; option premium is cheap.
