"WeightedMovingAverage"(金融指标) 有时缩写为 WMA. 是一个统计指标. 返回一个时间序列,它是前10个时间段的加权移动平均. 使用收盘价进行计算. FinancialIndicator["WeightedMovingAverage",n]使用前n个时间段. 时间序列中的初始值使用部分时间段计算.
The simple moving average (SMA) calculates the average price over a specific period, while the weighted moving average (WMA) gives more weight to present data. The exponential moving average (EMA) is also weighted toward the most recent prices, but the rate of decrease between one pr...

Further, some properties of WMA, such as the expected value, variance, and one-step ahead prediction variance, are also discussed. Keywords: moving average; weighed moving average; statistical process control; time-series forecast; sales demand...
WMA Weighted moving average.RemarksThe Line chart type is a convenient chart type to display the formula output.ExampleThe following example takes input from Series1's second Y value (Series1:Y2) and outputs a 20-day weighted moving average on Series2's first Y value (Series2:Y)....
