本策略名称为“自适应ATR追踪止损策略”。该策略使用ATR指标设定止损点,并在入场后将止损从紧固转为宽松,目的是追踪趋势运行而又控制风险。
策略的具体逻辑如下:
计算一定周期内的最高价和最低价范围作为入场信号,当价格突破该范围时产生入场信号。
入场后,最初采用较紧的ATR止损,止损点固定为ATR值的1.5倍。这可以限制入场后的损失。
在持仓阶段,将止损转为更宽松的ATR值4倍。止损继续追踪价格运行,但有更大空间allows需势继续延伸。
最后止损点始终跟踪最低价(多单)或最高价(空单),随价格波动调整,实现追踪止损效果。
价格跌破止损点(多单)或上破止损点(空单)时止损出场。
该策略的优势在于,采用自适应的止损机制,既保证了风险控制,也avoids过早止损。但ATR参数和倍数需优化,并配合趋势判断使用止损策略。
总体来说,动态追踪止损是提高策略获利概率的重要手段。灵活运用止损,能更好地维持趋势获利和控制风险。
