概述
跟踪线策略是一种基于布林带指标和平均真实波动范围(ATR)的趋势跟踪策略。它会动态调整趋势判断线,在突破布林带上轨时向上调整,突破布林带下轨时向下调整,从而实现对趋势的判断和跟踪。
策略原理
该策略首先计算布林带的上下轨,以及平均真实波动范围。然后判断价格是否突破布林带上轨或者下轨。
当价格突破上轨时,如果开启ATR过滤,则将趋势判断线设置为最低价减去ATR;如果不开启ATR过滤,则直接设置为最低价。
当价格突破下轨时,如果开启ATR过滤,则将趋势判断线设置为最高价加上ATR;如果不开启ATR过滤,则直接设置为最高价。
这样,趋势判断线就可以根据价格突破布林带上下轨来动态调整,从而实现对趋势的判断。
当当前趋势判断线高于上一个趋势判断线时,表示目前处于上涨趋势;当当前趋势判断线低于上一个趋势判断线时,表示目前处于下跌趋势。
根据趋势判断,该策略可以进行做多做空操作。
优势分析
- 动态调整趋势判断线,能够灵活地捕捉价格趋势
- 结合布林带指标,能在价格突破时及时判断趋势转折
- ATR参数的引入,可以过滤部分假突破信号
风险分析
- 布林带参数选择不当,可能导致频繁的假突破
- ATR参数选择过大,可能导致错过趋势转折机会
- 需考虑止损,以防止极端行情带来的损失
可以通过参数调整、引入止损来规避部分风险。也可结合其它指标进行过滤,提高突破的有效性。
优化方向
- 优化布林带和ATR的参数,寻找最佳配置
- 添加其它指标判断来过滤假突破
- 针对特定交易品种选择布林带周期和ATR周期
总结
跟踪线策略致力于在波动行情下捕捉价格趋势,是一种有效的趋势跟踪策略。通过参数调整和优化,是可以获得不错的收益的。不过也需要考虑风控止损和防范假突破。建议将本策略与其它指标或策略组合使用,可以进一步提升收益率。
