A market order is an order to immediately buy or sell cryptocurrency at the best available current price.
Unlike limit orders, you do not specify a price when you place a market order. When you place a market order, it is matched with an existing limit order with the best buy or sell price at the time of the request.
When to place a market order
Place market orders when you want your order to execute as soon as possible, regardless of the price.
