概述
该策略通过构建Price Channel,计算价格偏离中心线的距离,再结合均线过滤信号,实现对趋势的识别和跟踪。当价格突破Channel时产生交易信号。该策略同时具有趋势跟踪和突破两个特点。
策略原理
构建Price Channel
- 计算最近len周期内的最高价和最低价
- 中心线为最高价和最低价的平均值
- 距离为价格与中心线的绝对偏差
- 平滑距离求得上轨和下轨
判断趋势方向
- 当价格低于下轨,定义为跌趋势
- 当价格高于上轨,定义为涨趋势
产生交易信号
- 涨趋势下,价格低于开盘价或下破上轨时做多
- 跌趋势下,价格高于开盘价或上破下轨时做空
优势分析
- 能捕捉中长线趋势
- 结合突破信号,避免在震荡区间无效交易
- 可定制参数,适应不同品种
风险分析
- 震荡趋势下,可能出现较多小亏损
- 参数设置不当可能错过趋势反转
- 需关注交易频率,防止过度交易
优化方向
- 结合其他指标过滤信号
- 动态调整Price Channel参数
- 加入止损机制,优化资金管理
总结
该策略整体较为稳健,能有效跟踪中长线趋势,同时结合趋势突破产生交易信号。通过参数优化和信号过滤可进一步改进策略,使之能适应更多品种和市场环境。
