In virtual trading, common order types include market orders, limit orders, and stop orders. Market orders are executed immediately at the current market price, suitable for urgent transactions, but in highly volatile markets, the execution price may deviate. Limit orders are placed at a specific limit price, allowing for better buying and selling prices, but they may not be executed. Stop orders are initiated when the price reaches a trigger price, based on the set quantity, execution price, and method. Additionally, there are Maker orders, which ensure the order remains on the order book and enjoy lower fees. Understanding these order types can help you operate more flexibly in virtual trading.
