Regime pinning · moves get faded back to the walls.
Each wall is the strike carrying the heaviest open interest within 15% of price, call above as resistance, put below as support, pooled across all listed expirations. It is a structural positioning level, not a single expiry pin. Max pain is tracked separately.
The Read
$BIIB is in long gamma at a calm heat 31, which means dealers are pinning moves and damping volatility. The $210 call wall is fresh today but has held 76% of tests previously, while the $180 put wall also holds strong at 78%, suggesting these levels act as reliable support and resistance. Spot stands 6.4% above its gamma flip at $181.05, so any pullback likely meets solid buying interest.
