Exchange supports two order types: Market and Limit orders. A Market Order is a type of order to buy or sell cryptocurrencies immediately. It ensures that the order will be executed, but does not guarantee the execution price. A Market Order generally will be executed at or near the current bid or ask price. However, the last-traded price is not necessarily the price at which a Market Order will be executed. A Limit Order is a type of order that you place on the order book with a specific limit price. This price is determined by you, meaning that the trade will only be executed if the market price reaches your limit price. Therefore, you may use Limit Orders to buy or sell at prices lower or higher than the current market price. Limit Orders are placed on the order book and are not executed immediately.
