Bid ask意思

"Bid" and "ask" are terms used in financial markets, particularly in the context of trading assets such as stocks, bonds, commodities, or currencies. They refer to the prices at which buyers (market participants known as "bidders" or "buyers") are willing to buy and sellers (market participants known as "askers" or "sellers") are willing to sell.

The difference between the bid price and the ask price is known as the bid-ask spread. This spread represents the cost of trading the asset and is a reflection of the supply and demand for the asset in the market. When a trade occurs, the bidder buys at the ask price, and the asker sells at the bid price. The bid-ask spread is a key factor in determining the liquidity and efficiency of a market.
