该策略是John Ehlers开发的RSI指标的改进版本。其最大优势是在降低滞后性的同时平滑RSI曲线。
计算价格的6条平均值xValue。
根据xValue计算上涨总和CU23和下跌总和CD23。
计算Normalized RES值nRes,即CU23/(CU23 + CD23)。
比较nRes与上下阈值,生成多空信号。
可选反向交易。
根据信号进行多空交易。
该策略通过改进RSI指标计算方式有效平滑了曲线,在一定程度上减少了误报信号。优化参数设置和添加其他过滤条件可以进一步提高策略表现。但作为倾向型系统,无法完全避免滞后问题。整体来说,该策略是一个简单可靠的突破系统,值得进一步研究优化。
