Bid And Ask
The term "bid and ask" (also known as "bid and offer") refers to a two-way price quotation that indicates the best potential price at which a security can be sold and bought at a given point in time. The bid price represents the maximum price that a buyer is willing to pay for a share of stock or other security. The ask price represents the minimum price that a seller is willing to take for that same security. A trade or transaction occurs when a buyer in the market is willing to pay the best offer available—or is willing to sell at the highest bid.The difference between bid and ask prices, or the spread, is a key indicator of the liquidity of the asset. In general, the smaller the spread, the better the liquidity.
