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
$MRK is in long gamma at heat 38, which means dealer hedging damps price swings. The $125 call and $110 put walls are both untested yesterday; however, given their hold rates of 71% and 86%, respectively, these levels dealers typically defend. Spot sits 8.1% above the $110.29 gamma flip, so any move down faces a strong test at the $110 put.
