Limit orders can set the price, the transaction price does not exceed the price when buying, and not lower than the price when selling. The limit order is valid on the day, and the uncompleted part can be cancelled. Limit order is an order for foreign exchange contract purchases and sales at a price determined by the customer or the price at the time of contract performance. It is the second type of order frequently used in foreign exchange trading orders. It specifies the highest price at which buyers are willing to buy or the lowest price at which sellers are willing to sell.
