The ask price (or simply “ask”) is the price at which a trader is offering to sell an asset. In an order book, the lowest ask price is always higher than the highest bid price, and the difference between them is called the spread.
When you want to buy cryptocurrency, you should consider the ask price. Usually, the order in the order book with the lowest asking price is the first to be filled when a trader places a market buy order.
You can check the current ask price under the price chart on the Trade page of the CEX.IO website. It’s displayed in the Sell orders box.
