# 威廉姆斯百分比范围

威廉姆斯百分比范围技术指标 (%R) 是一款动态技术指标，其判断行情是否处于超买/超卖。威廉 %R 与[随机振荡器](https://www.metatrader5.com/zh/mobile-trading/iphone/help/chart/indicators/oscillators/stochastic_oscillator)十分相似。唯一的区别在于 %R 的标尺自顶至下，而随机振荡器有内部平滑。

指标值若在 -80% 到 -100% 范围表示行情处于超卖。指标值若在 -0% 到 -20% 范围表示市场处于超买。为了按照自顶至下方式显示指标，在威廉姆斯百分比范围数值前加负号 (例如 -30%)。不过在进行分析的时候，应忽略负号。

如同所有的超买/超卖指标，您在下单前最好等待品种价格改变方向。例如，如果超买超卖指标显示超买条件，则在抛售资产之前等待价格回落是明智之举。

威廉姆斯百分比范围指标的一个有趣现象就是它具有预测基础证券价格逆转的神奇能力。指标几乎总会在证券价格到达峰值并回落的几天前就形成峰顶并反身回落。同样，威廉百分比范围通常会在证券价格回升的几天前形成一个波谷后反身回升。

## 计算

以下是 %R 指标的计算公式, 它与 [随机振荡器](https://www.metatrader5.com/zh/mobile-trading/iphone/help/chart/indicators/oscillators/stochastic_oscillator) 的计算公式十分相似:

%R = -(MAX (HIGH (i - n)) - CLOSE (i)) / (MAX (HIGH (i - n)) - MIN (LOW (i - n))) * 100

其中:

CLOSE (i) ― 本期收盘价;
MAX (HIGH (i - n)) ― 之前 n 周期最高价的最大值;
MIN (LOW (i - n)) ― 之前 n 周期最低价的最小值。
