Spread

Spread

The spread, specifically the bid-ask spread, represents the difference between the highest price a buyer is willing to pay (the bid) and the lowest price a seller is willing to accept (the ask) for an asset. This difference constitutes a transaction cost for market participants and is a key indicator of market liquidity. A narrow spread signifies high liquidity and efficient price discovery, while a wide spread suggests illiquidity or high volatility. It reflects the cost of immediate execution.
