What the positioning says

●Call wall at $60 (5k contracts), 8% above spot — the upside strike the crowd is already parked on; often acts as near-term resistance.
●Put wall at $25 (5k contracts), 55% below spot — the hedge floor; often acts as support.
●30-day ATM implied volatility is 20% — calm pricing; option premium is cheap.
