Market orders and limit orders are two commonly used types of orders in financial trading. Market orders aim for quick execution, as they are executed immediately at the current best market price, providing high trading efficiency and the ability to seize market opportunities in a timely manner. However, the execution price may deviate from expectations due to market fluctuations, especially when liquidity is poor, leading to significant slippage risk.

Limit orders, on the other hand, focus on price control. Investors set a specific price, and trades only occur at that price or a better one. This can avoid unfavorable execution prices, but trades may not be executed if the market price does not reach the set price, resulting in longer wait times.
