Chapter 4  用KD随机指标判断中短期行情

KD指标,又称随机指标,英文名称是Stochastics oscillator,是一种对中短期行情研判比较准确的领先指标。

KD指标是根据统计学的原理,通过一个特定周期内出现的最高价、最低价,以及最后一个计算周期的收盘价及三者的关系,来计算最后一个计算周期的未成熟值RSV,然后根据平滑移动平均线的计算方法来计算K值和D值,并绘成曲线图来研判汇价走势。

使用KD指标确认市场趋势

KD线等于是移动平均线的延伸,因为移动平均线只以收盘价来计算,KD线则除了收盘价之外,还有最高价与最低价,对于短期测试市场趋势,KD线会更灵敏。如果行情是一个明显的涨势,会带动K线与D线向上走升。

KD值的区间也是从0到100,通常KD值在80以上被视为超买区,这时候投资者就要注意找卖点了(图4.4.1);当KD值在20以下则视为超卖区,这时候就要注意找买点(图4.4.2)。
