行情快速波动时，订单类型选择更重要：市价单重在成交，限价单设定价格边界，止损单触发后仍可能滑点。

Fast markets make order type selection more important: market orders prioritize fills, limit orders set price boundaries, and stop orders can still slip after triggering.

市价单看起来简单，但薄订单簿和快速行情可能导致成交价变差。交易者下单前应检查价差、深度、订单规模和平台保护规则。

Market orders feel simple, but thin books and fast markets can create poor fills. Traders should check spread, depth, order size and protection rules before execution.

OCO订单可以把止盈限价单和止损限价单组合在一起，但交易者必须理解触发价、限价和未成交风险。

An OCO order can pair a take-profit order with a stop-limit order, but traders still need to understand trigger price, limit price and partial-fill risk.
