公式

S-RoC = EMA(N)/EMA(N — K)*100, where


N – number of periods;

K – smoothing factor.

应用

S-RoC是技术分析中最简单的震荡指标。它很容易使用,擅长产生可用的交易价格反转的真实信号。从这一点来说,相比顺势交易,该指标更适合于逆势交易策略。因为当很强的价格走势存在时S-RoC指标能产生很多伪信号。

如果S-RoC指标加速,能指示价格上涨。相反地,如果指标下落,上涨的步伐也会变慢。当S-RoC指标反转,趋势或会改变。

因此,S-RoC有助于确定牛市或熊市中的主要趋势。就此而言,S-RoC能用于指示长期趋势的方向。

独立的信号行为如下:

  • 如果S-RoC跌至零水平线之下然后向上折返,买入信号产生。
  • 如果S-RoC上升至零水平线以上并且向下折返,卖出信号产生。
  • 背离/一致信号也能由S-RoC指标产生。这种信号不但十分强烈并且十分重要,所以应该被用于交易。
