Limit Order is an order to buy or sell a cryptocurrency with a price restriction.
If the order is executed, it will only be executed at the specified limit price or better. However, there is no guarantee of execution.
A Limit Order may be appropriate when you believe you can buy at a lower price or sell at a higher price than the current quote.
For an instant execution on a limit order, you must set a price that is already in the open order list.
