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

$MUB is in short gamma at heat 39, meaning dealer hedging amplifies moves rather than dampening them. The $109 call wall has held 3 sessions running, while the $104 put wall remains untested yesterday. Spot sits 1.4% below the $108.1 flip, so any push higher could see further upside traction.
