What the positioning says

●Call wall at $360 (3k contracts), 6% above spot — the upside strike the crowd is already parked on; often acts as near-term resistance.
●Put wall at $335 (2k contracts), 1% below spot — the hedge floor; often acts as support.
●30-day ATM implied volatility is 21% — calm pricing; option premium is cheap.
