Illiquid Strike Depth

Definition

Illiquid strike depth denotes the limited supply of contract interest available at specific price levels within an options order book, typically resulting in wider bid-ask spreads for derivatives tied to volatile underlying crypto assets. Traders often encounter this phenomenon when seeking execution at out-of-the-money or deep-in-the-money strikes where market maker activity remains sparse. A lack of volume at these nodes forces participants to accept significant slippage or manage execution through alternative routing strategies to mitigate adverse price impact.
