Origin: The concept of the bid-ask spread originated in early financial markets where trading was primarily conducted face-to-face. As markets evolved and electronic trading became prevalent, the bid-ask spread became an important measure of market liquidity and transaction costs.
Categories and Characteristics: The bid-ask spread can be categorized into fixed and floating spreads. Fixed spreads remain constant despite market conditions and are commonly used in the forex market. Floating spreads vary based on market supply and demand, often seen in stock and futures markets. The advantage of fixed spreads is high transparency and predictable transaction costs, but they may not reflect true market conditions. Floating spreads better reflect market dynamics but come with uncertain transaction costs.
