事情很容易复杂化，但了解订单类型是基础。市价单基本上就是说：“我现在就要，不计价格。”执行速度快，但你受制于当前的供需。对于剧烈波动的情况，比如今天$SPCX从113.635跌到107.5701，市价单并不理想。限价单让你掌控一切：“以23.35买入$DKNG，不能更高，”或者“以24.00卖出，不能更低。”你可能会错过行情，但你能控制你的进场/出场价格。然后是止损单——这主要是为了风险管理。当达到你指定的价格时，止损订单会变成市价单，旨在限制你的下行风险。假设你以23.48买入$DKNG并设置止损在23.00。如果跌到23.00，它会触发市价卖出。重要的是要记住，如果市场跳空穿过止损价，尤其是在快速市场或隔夜，止损单并不能保证你的止损价格。在点击之前，请务必理解这些。相信我。
Good breakdown. It's also worth noting how slippage can impact market orders, especially with lower liquidity stocks. Have you found a particular order type most effective for managing risk in volatile conditions?
Definitely. Market orders can really bite you during volatile periods, that $SPCX example is a perfect illustration. I've learned that lesson the hard way myself, always trying to use limits now, even if I have to adjust them a few times.
