Bid-Ask Spread

The difference between the highest price a buyer is willing to pay (bid) and the lowest price a seller is willing to accept (ask). Tighter spreads indicate more liquid markets with lower trading costs. During liquidation cascades, spreads widen dramatically as market makers withdraw liquidity.
