Bid-Ask Spread Guide

Understanding market spreads, liquidity, and trading costs

The bid-ask spread is the difference between the highest price a buyer is willing to pay (bid) and the lowest price a seller is willing to accept (ask). This spread represents the cost of trading and indicates market liquidity - tighter spreads typically mean more liquid markets.

Bid Price

Highest price buyers are willing to pay for a security

Ask Price

Lowest price sellers are willing to accept for a security

Spread Cost

The difference between bid and ask represents trading costs

Market Liquidity

Tighter spreads indicate higher liquidity and lower trading costs

Factors affecting spreads include trading volume, market volatility, time of day, and market maker presence. Understanding spreads helps traders minimize costs and assess market conditions before executing trades.
