# 限价

限价委托是按特定价格或更优价格买入或卖出的指示。与在 goodcryptoX 服务器上监控、直到触发条件满足的条件单（如止损单、跟踪单或止盈/止损组合单）不同，限价委托会立即发送到交易所并直接放入交易所的订单簿。

由于它存在于交易所而非我们的服务器上，限价委托的执行、成交行为或被拒完全由交易所决定。一旦提交，它将独立于 goodcryptoX 运作：即使我们的服务器出现停机，你的限价委托仍会保留在订单簿上并根据交易所的撮合引擎继续正常执行。

限价单可用于直接开仓或平仓，并且在由 goodcryptoX 触发的止损限价单和跟踪止损限价单中也作为执行环节。网格和定投（DCA）机器人也依赖于原生限价单。
