Options Bid Ask Spreads

Definition

The options bid ask spread represents the numerical variance between the highest price a market participant is willing to pay to purchase an option and the lowest price a seller is prepared to accept for the same instrument. Within cryptocurrency derivatives, this differential functions as a primary indicator of market liquidity and transaction friction for traders. Narrower margins typically suggest higher trading activity and robust order book depth, while wider gaps often signal fragmented liquidity or periods of elevated market stress.
