●Call wall at $195 (2k contracts), 17% above spot — the upside strike the crowd is already parked on; often acts as near-term resistance.
●Put wall at $145 (956 contracts), 13% below spot — the hedge floor; often acts as support.
●30-day ATM implied volatility is 25% — calm pricing; option premium is cheap.
