Spread

The spread, specifically the bid-ask spread, represents the fundamental difference between the highest price a buyer is willing to pay for an asset (the bid price) and the lowest price a seller is willing to accept (the ask price). This seemingly small gap is crucial in financial markets, as it inherently reflects the immediate profit margin for market makers or brokers who facilitate trades, buying at the bid and selling at the ask. It also acts as a real-time indicator of market liquidity and efficiency, with tighter spreads typically found in highly liquid markets with many buyers and sellers.
