概述
该策略结合了多种不同的移动平均线,实现了一个简单的趋势跟踪策略。策略同时具有过滤噪音的功能。
策略原理
该策略首先会对收盘价进行平滑,可以选择是否使用Heiken Ashi收盘价。然后会调用smoothMA函数,实现多次叠加平滑移动平均线。smoothMA函数首先调用variant函数,variant函数可以生成多种不同类型的移动平均线,如SMA、EMA、DEMA等。variant函数生成指定类型和长度的移动平均线之后,smoothMA会通过递归的方式多次叠加调用variant函数,从而实现多重平滑。最终形成平滑度很高的移动平均线。当平滑移动平均线上涨时产生买入信号,当下跌时产生卖出信号。
优势分析
- 多重叠加移动平均线,能够有效滤除市场噪音,识别趋势。
- 支持多种移动平均线类型,如SMA、EMA、DEMA等,可以灵活组合使用。
- 支持Heiken Ashi技术,可以过滤假突破。
- 策略简单易用,容易实施。
- 允许自定义移动平均线长度、类型和平滑次数,可以针对不同品种优化参数。
风险分析
- 多重叠加移动平均线会产生滞后,可能错过趋势最初的变化。
- 仅使用简单的移动平均线系统,在震荡行情中无法有效获利。
- 未考虑交易成本,实际交易中交易成本会降低盈利能力。
- 未设置止损,存在亏损扩大的风险。
可以考虑结合其他指标如MACD、KDJ等使用,识别趋势信号更加准确。优化移动平均线参数,降低滞后。设置合理的止损水平,控制单笔亏损。同时注意控制交易频率,降低交易成本。
优化方向
- 可以尝试不同长度和类型的移动平均线组合,找到最佳参数。
- 可以考虑在策略中加入其他技术指标,形成更系统的入市和出市规则。
- 可以设定交易时间,避免主要宏观事件对策略的影响。
- 可以根据品种特性调整参数,寻找最佳参数组合。
- 可以设定止损和止盈水平,控制交易风险。
总结
该策略通过多重叠加移动平均线实现趋势跟踪,可以有效滤除市场噪音。优点是简单易用,可以灵活调整参数。但仅使用移动平均线系统仍有盈利能力受限的问题。可以考虑与其他技术指标组合使用,同时注意控制交易风险,优化参数,提高策略效率。
