# 限价

限价单是以特定价格或更优价格买入或卖出的指令。与条件委托（例如止损单、跟踪委托或止盈/止损组合）不同——这些委托会在 goodcryptoX 服务器上监控直到触发条件满足——限价单会立即发送到交易所并直接放在交易所的订单簿上。

由于它驻留在交易所而非我们的服务器上，限价单的执行、成交行为或被拒完全由交易所决定。提交后，它独立于 goodcryptoX 运行：即使我们的服务器出现停机，你的限价单仍会保留在订单簿上并按照交易所的匹配引擎正常继续执行。

限价单可用于直接进出头寸，同时也作为由 goodcryptoX 触发的止损限价和跟踪止损限价订单中的执行部分。网格和定投（DCA）机器人也依赖原生限价单。
