Ask price is the lowest price that a seller is willing to accept to sell an asset in the market, such as a stock, bond, or currency. The ask price is also known as the selling price, and reflects the price at which the seller is willing to offload the asset.

In trading on the stock market or crypto market, the ask price indicates the price at which a seller is willing to sell an asset to a buyer. This price is always compared to the bid price, which is the price a buyer is willing to pay to purchase the asset. The difference between the ask price and the bid price is called the spread. This spread is an indicator of an asset's liquidity; the smaller the spread, the more liquid the market for that asset.

The ask price is determined by the seller based on various factors, including market conditions, the amount of the asset being traded, and their investment objectives. In the context of electronic trading, the ask price appears in the order book and is updated in real-time according to changes in demand and supply in the market.
