The bid-ask spread represents the difference between the best bid (highest price a buyer is willing to pay) and the best ask (lowest price a seller is willing to accept). Tracking the spread provides insights into market liquidity, trading costs, and potential slippage. A narrower spread typically signals higher liquidity and lower transaction costs, while a wider spread can indicate lower liquidity or heightened volatility.
