#订单类型解析 Order types affect transaction execution and risk control. Common types include market orders, limit orders, stop-loss orders, etc. Market orders execute immediately at the current best price, quick but may have slippage, suitable for fast trading; limit orders set a target price and only execute when reached, allowing for cost or profit control but may not execute; stop-loss orders convert to market orders when the price hits the stop-loss level, protecting profits and limiting losses; stop-limit orders become limit orders after being triggered, avoiding slippage but may not execute. When choosing, market orders emphasize speed, limit orders emphasize price, and the appropriate order should be selected based on strategy and market conditions.
